NEET-NET Crisis
Tags: GS – 2- Governance-Issues relating to development and management of Social Sector- Education
Why in the news?
- Recently, issues such as paper leaks, incorrect results prompting aspirant suicides, and inconsistent grace marks allocation have severely undermined public confidence in the National Testing Agency (NTA).
Recent Paper Leaks and Their Impact
- Recent incidents surrounding NEET have exposed serious flaws in its administration.
- Instances of leaked examination papers and the dissemination of incorrect results have not only shattered trust but have also been linked to tragic suicides among aspirants.
- In a concerning development, an unprecedented 67 students scored perfect marks, raising suspicions of systemic manipulation.
- Moreover, over 1,560 students received grace marks without transparent justification, exacerbating doubts about the fairness of assessments conducted by the National Testing Agency (NTA).
- The government’s decision to cancel the National Eligibility Test (NET) due to similar issues further compounds concerns about the integrity of these examinations.
Origin of NEET Policy, its Objectives and Implementation Challenges:
- Standardising Educational Competence:
- The implementation of NEET was primarily driven by the necessity to standardise the educational competence of students entering medical colleges.
- Before NEET, there was a noticeable disparity in foundational knowledge of basic sciences like Chemistry, Physics, and Biology among students from different educational backgrounds.
- This variation often resulted in significant differences in the quality of medical graduates, with some students lacking adequate understanding of these critical subjects.
- NEET aimed to establish a minimum standard of competence in the basic sciences for all medical aspirants, regardless of their educational origins.
- Reducing the Number of Entrance Examinations:
- Prior to NEET, India’s medical aspirants had to contend with multiple entrance examinations—approximately 46 exams administered by various medical colleges and institutions, each with its unique syllabus, format, and evaluation criteria.
- This proliferation of exams caused considerable stress and confusion for students, who were required to prepare for and appear in numerous tests within a short timeframe.
- NEET sought to consolidate these disparate exams into a single, standardised test, simplifying the admission process, reducing financial and logistical burdens, and ensuring a more straightforward and equitable selection process.
- The government aimed to streamline admissions by implementing a unified entrance examination that would be efficient and less cumbersome for all stakeholders involved.
- Eliminating Capitation Fees:
- NEET also aimed to tackle the widespread practice of capitation fees in private medical colleges.
- Capitation fees are payments made by students to secure admission, often bypassing merit-based selection criteria.
- This practice compromised the quality of medical education and created barriers for economically disadvantaged students seeking admission.
- By basing admissions solely on NEET scores, the policy aimed to curb the discretion of private medical colleges in student selection.
- This merit-based approach was intended to ensure that admissions were granted solely to the most qualified candidates, irrespective of their financial background.
- The elimination of capitation fees was viewed as a crucial step towards promoting transparency and fairness in the admission process, thereby enhancing the credibility of medical education in India.
Challenges in Implementation:
- Initially, in 2013, the Supreme Court suspended the scheme following challenges from private colleges, which argued that NEET’s centralised process encroached upon their autonomy.
- However, in 2016, a five-judge bench reinstated NEET, underscoring the necessity of a unified examination system.
- A persistent challenge was the lack of a uniform standard for school education across India.
- Central government schools followed the CBSE syllabus, known for its rigour, while state boards and private schools, including those offering International Baccalaureate (IB) programs, had different curricula.
- This disparity sparked accusations of bias, with NEET’s standards perceived to favour students from CBSE backgrounds.
| Case study: The Opposition of NEET in Tamil Nadu: Tamil Nadu has consistently opposed NEET, advocating for its state policy of linking medical college admissions to high school performance. The state’s Expert Committee, led by Justice A.K. Rajan, revealed that rural students and those from Tamil medium schools were disproportionately disadvantaged by NEET. Between 2017 and 2021, admissions of Tamil medium students plummeted from 15% to as low as 1.6%, and rural student admissions dropped from 62% to 50%. This decline has significant implications for Tamil Nadu’s public health system, which relies on rural students to work in primary health centres. |
Necessary Key Reforms to Address the Crisis of NEET:
- Extending the MBBS Degree:
- Consider extending the MBBS degree to six years, including a pre-medical year to standardise knowledge in Zoology, Chemistry, and Physics.
- This approach has historical precedent in India’s medical education system, ensuring all students meet essential foundational requirements.
- Decentralising Examinations:
- Implement decentralisation of the examination process, allowing states and universities to conduct their own entrance exams.
- Centralisation under NEET has caused disparities, especially for students from non-CBSE backgrounds.
- State and university-level exams can better align with local curricula, enhancing relevance and fairness.
- Constituting Regional Boards:
- Introduce regional examination boards to standardise exams within specific geographic areas.
- These boards can operate under central guidance while adapting to local educational standards.
- This approach balances national standardisation with local relevance, ensuring comprehensive and equitable assessments.
- Improving School Education:
- Focus on improving the quality of school education nationwide through governance, curriculum reform, and infrastructure enhancement.
- Transition from rote learning to inquiry-based and critical thinking-oriented education.
- Regular curriculum updates should reflect the latest scientific and educational advancements.
Conclusion:
The NEET crisis exposes systemic failures in India’s school education system. To resolve this, reforms should focus on improving schools, decentralising exams, and strengthening oversight. These efforts are crucial to restoring confidence, fairness, and integrity in the examination process for all students.

Tamil Nadu hooch tragedy
GS-3 , Science & technology- Health — Impact of methanol poisoning from illicit alcohol
Why in the news?
- Recently, in Tamil Nadu’s Kallakurichi, at least 38 people have died and around 100 others are in the hospital after drinking spurious liquor, also known as hooch.
What is the science of Creating Alcohol?
- Alcohol production relies on two main processes: fermentation and distillation.
- Fermentation:
- Fermentation involves the chemical reaction where yeast or bacteria act on sugars derived from grains, fruits, or sugarcane to produce ethanol, the alcohol found in beverages.
- Alcohol Content Variation: Alcoholic beverages vary in alcohol content:
- Beer typically contains around 5% alcohol by volume.
- Wine ranges from approximately 12% alcohol by volume.
- Distilled spirits, such as whiskey and vodka, have alcohol contents typically around 40% or higher.
- Fermentation involves the chemical reaction where yeast or bacteria act on sugars derived from grains, fruits, or sugarcane to produce ethanol, the alcohol found in beverages.
- Role of Distillation:
- Distillation is crucial, particularly for beverages with higher alcohol content.
- As more sugars are converted into alcohol during fermentation, the environment can become toxic for the fermenting microorganisms.
- Distillation Process:
- Distillation separates alcohol from the fermented mixture by:
- Evaporating the liquid to create alcohol vapour.
- Condensing the vapour back into liquid form.
- This process concentrates the alcohol, ensuring a more potent final product compared to the original fermented mixture.
- Distillation separates alcohol from the fermented mixture by:
Adverse effect of Ethanol on Human Health:
- Ethanol Metabolism:
- Ethanol (C2H5OH) is metabolised in the liver and stomach by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH).
- Acetaldehyde Effects:
- The harmful effects of alcohol consumption, including hangovers and cancer risks, stem largely from acetaldehyde.
- WHO’s Alcohol Warning:
- Contrary to common belief, the World Health Organization (WHO) asserts that no level of alcohol consumption is safe for health.
What is Hooch/Spurious Liquor?
- About Hooch:
- Hooch, derived from the Hoochinoo tribe of Alaska known for strong liquor, refers to poor quality alcohol lacking rigorous quality control, often produced in crude, homemade settings.
- Production Process:
- Hooch, like all alcohol, is made through fermentation and distillation. It involves distilling a fermented mixture of local yeast, sugar, or fruit waste.
- Risks of Methanol:
- During distillation, both ethanol (boiling point 78.37 °C) and highly toxic methanol (boiling point 64.7 °C) can concentrate. Improper distillation can result in high methanol levels in the final product.
- Health Hazards:
- High methanol concentrations in hooch can cause severe toxicity, including cerebral edema, haemorrhage, and death. Differentiating safe hooch from toxic variants is challenging prior to consumption
Regulation of Methanol in India:
- Inclusion in Hazardous Chemical Rules:
- Methanol is listed in Schedule I of the Manufacture, Storage, and Import of Hazardous Chemical Rules 1989, indicating its regulatory control due to its hazardous nature.
- Food Safety Regulations:
- Under the Food Safety and Standards (Alcoholic Beverages) Regulations 2018, specific limits for methanol content in various liquors are stipulated.
- For example, coconut feni must have methanol “absent,” while country liquor can contain up to 50 grams per 100 litres.
- Quality Standards:
- Indian Standard (IS 517) dictates the methods for assessing methanol quality.
- The Tamil Nadu Denatured Spirit, Methyl Alcohol, and Varnish (French Polish) Rules 1959 govern how methanol packaging and signage should be handled to ensure safety and compliance.
How can Methanol Poisoning be Treated?
- Administration of Ethanol:
- Ethanol, administered in pharmaceutical grade under medical supervision, competes with methanol for the alcohol dehydrogenase (ADH) enzymes in the body.
- By doing so, ethanol prevents methanol from being metabolised into toxic formaldehyde and subsequently into formic acid, which is responsible for the severe effects of methanol poisoning.
- This competition prevents methanol from being metabolised into toxic formaldehyde, thereby reducing its harmful effects.
- Use of Fomepizole:
- An alternative treatment is the administration of fomepizole, an antidote that inhibits the action of ADH enzymes.
- By slowing down ADH activity, fomepizole helps the body metabolise methanol into formaldehyde at a slower rate.
- This allows the body more time to excrete formaldehyde safely, thereby preventing severe complications such as cerebral edema and death.

GM Crops Promise Food Security
Tags: GS- 3- Ecology & environment- Biodiversity– GM crop in India- Food Security
Why in the News?
- A new “gene revolution” is being promoted as a solution to increasing global food demand and the impact of climate change on agriculture.
What does the World Economic Forum (WEF) say?
- The World Economic Forum (WEF) advocates for genetically modified (GM) technology, viewing it as crucial for ensuring food security for a global population projected to reach 10 billion by 2050.
- Research efforts are focused on developing new strains of staple crops such as rice, maize, wheat, potato, and cassava, aiming to enhance their resilience to extreme weather conditions and emerging climate-induced diseases.
- The latest advancements in bioengineering technologies can help plants and soils capture and store atmospheric carbon, contributing to the reduction of planet-heating carbon levels.
- Additionally, projects are underway to optimise photosynthesis in crops like maize and rice, with the goal of improving yields and reducing atmospheric carbon.
Industrial-Scale GMOs Perpetuate Climate Change:
- Critics argue that GM crops maintain an “agro-industrial system” responsible for significant greenhouse gas emissions.
- Current food systems contribute to about one-third of global greenhouse gas emissions.
- GMOs often involve large-scale monocultures that require substantial amounts of artificial fertilisers, pesticides, and irrigation.
- This system is criticised for being energy-intensive and unsustainable, primarily benefiting large agro-industrial companies that dominate the seed, food, pesticide, and fertiliser markets.
Present Scenario:
- Over half of harvested cropland in the US uses genetically modified seeds.
- Despite the widespread adoption of GM crops, food insecurity remains prevalent, with 250 million people in nearly 60 countries facing crisis-level food insecurity.
- Successful campaigns, such as those in the Philippines, have led to production moratoriums on certain GM crops due to health and ecological concerns.
Are Non-GM Ecological Crops Also a Food Security Solution?
- Resistance to GMOs persists due to concerns about their safety and ecological impact.
- Non-GM ecological approaches face challenges, primarily because most research funding originates from large agri-biotech companies.
- Ecological, non-GM crops aim to produce toxic-free food and nurture biodiverse ecosystems capable of resisting and mitigating climate change.
- Ongoing development of ecological, non-GM seed, food, and nutrition systems is underway to address food security in a warming world.
Note: India has approved the commercial cultivation of only one GM crop, Bt cotton. No GM food crop has been approved for commercial cultivation in the country.
Way forward:
- Enhanced Regulatory Oversight and Support for Ecological Practices:
- Strengthen regulations to ensure the safe development, testing, and deployment of GM crops while simultaneously supporting research and development of non-GM ecological farming practices.
- Public Awareness and Inclusive Research Funding:
- Launch comprehensive public education campaigns to inform communities about the benefits and risks of GM and non-GM crops, promoting informed decision-making.

‘Blood Money’ in Islamic Law
Tags: GS-2 , Polity & Governance- Transparency & Accountability – Citizens Charters
Why in the news?
- The Indian Government has authorised the transfer of $40,000 for initial discussions on securing Nimisha Priya’s release from a Yemeni prison.
- Priya’s mother is currently in Yemen, seeking to commute her death sentence by offering “blood money” to the family of the deceased.
About Nimisha Priya’s Case:
- Priya, a nurse who relocated to Yemen in 2008, married Tomy Thomas in 2011, and later returned to Yemen, where she encountered abuse and exploitation from Talal Abdo Mahdi.
- This situation culminated in Mahdi’s death and Priya’s subsequent arrest. The $40,000 payment is intended to start negotiations for Priya’s release.
- To commute the death penalty, Priya’s family may need to gather between $300,000 to $400,000.
- The ‘Save Nimisha Priya International Action Council’ is actively fundraising to meet this financial requirement.
What is Blood Money?
- According to Islamic law, victims of crimes, particularly in cases of murder, have the authority to decide on the punishment of the criminals.
- This principle applies specifically to the families of the victims.
- While murder typically incurs the death penalty, the victim’s family, known as heirs, have the option to “forgive” the perpetrator in exchange for monetary compensation.
- This compensation is known as Diyya or “blood money” and finds its basis in the Holy Quran.
- The concept of blood money is applicable in cases of unintentional homicide (Qatl Khata) or accidental death, as well as in situations involving bodily injury or harm caused by negligence or unintentional actions.
The implications of blood money in Islamic law:
- Encouragement of Forgiveness:
- It allows the victim’s family to choose to forgive the perpetrator in exchange for compensation, reflecting mercy and the importance of reconciliation.
- Flexible Compensation:
- Unlike rigidly defined amounts, Islamic scriptures do not specify a fixed sum for blood money.
- Instead, the compensation is typically determined through negotiations between the families involved or their representatives.
- Negotiation Process:
- This negotiation involves discussions between the perpetrator’s family and the victim’s family, seeking a resolution that both parties find acceptable.
- Minimum Compensation in Some Countries:
- While the Quran does not prescribe specific amounts, certain Islamic countries have established minimum compensation thresholds.
- These standards aim to ensure fairness and consistency in resolving cases involving blood money.
The significance of blood money in Islamic law:
- Encouragement of Forgiveness:
- Forgiveness from the victim’s family is deeply valued and praised in Islam.
- By accepting blood money, the family of the victim demonstrates mercy and compassion towards the perpetrator or their family.
- Prevention of Retaliation:
- Blood money serves as a mechanism to prevent cycles of vengeance or retaliation (known as Qisas).
- Instead of seeking revenge through retributive justice, accepting blood money allows for the resolution of disputes in a peaceful and reconciliatory manner.
- Promotion of Reconciliation:
- The concept of blood money promotes reconciliation between conflicting parties.
- By negotiating and agreeing on a compensation amount, both the victim’s family and the perpetrator’s family can reach a mutual understanding and closure.

Striped caecilian
Tags: GS-3 , Ecology & Environment – Biodiversity- Species
Why in the News?
- A limbless amphibian, the striped caecilian (Ichthyophis spp), was newly discovered in Kaziranga National Park and Tiger Reserve (1,307.49 sq. km) during a recent herpetofauna survey conducted by Assam’s wildlife officials.
| Herpetofauna: Herpetofauna encompass reptiles and amphibians collectively, derived from “herpeto-” meaning “creeping animal” in Greek, combined with “fauna” denoting animal species in a specific area or period. They fulfil crucial ecological roles: regulating insect populations, serving as indicators of environmental health, and functioning as both predators and prey in ecosystems. |
About Striped Caecilian:
- The Striped Caecilian (Ichthyophis spp.) is a limbless amphibian from the family Ichthyophiidae.
- Due to their elongated, cylindrical bodies and lack of limbs, caecilians are frequently confused with snakes or worms.
- They inhabit primarily tropical regions across Africa, Asia, and the Americas.
- Their habitats typically include underground burrows or moist soil environments.
Key features of the Striped Caecilian include:
- They possess smooth, cylindrical bodies adorned with a ringed or striped pattern, earning them the name “striped.”
- Caecilians are primarily fossorial (burrowing), spending much of their lives underground or in leaf litter, which makes them elusive and challenging to observe.
- They are carnivorous, feeding on small invertebrates found in soil and leaf litter.
- Caecilians typically have poor eyesight and rely heavily on chemoreception to detect chemicals in their environment, aiding in prey location.
- Caecilians exhibit unique reproductive strategies, including both live births and egg laying. Some species display parental care, with adults guarding eggs or young offspring
