Preparing for CSIR NET Life Sciences to secure Junior Research Fellowship or Assistant Professor eligibility? Chandu Biology Classes offers dedicated Life Sciences coaching, available online to students anywhere in India and offline at our Hyderabad center, built specifically around the exam’s actual pattern by faculty who specialize exclusively in this subject.
This is the most important update for any CSIR NET Life Sciences aspirant right now, and we want every visitor to this page to see it clearly before anything else.
On 13 January 2026, CSIR-HRDG issued official notice number AB-CSIR0HRDG(OT)/11/2024-Admin-HRDG confirming that CSIR-NET (Life Sciences) and DBT-BET (Biotechnology) are being merged into a single, unified national-level examination: the Joint CSIR-UGC-DBT JRF-NET. This takes effect from the December 2026 cycle onward. The June 2026 cycle was still conducted under the previous, separate CSIR NET format.
According to the official notice, the primary objective is to streamline the national examination framework, eliminate redundancy between two exams that tested substantially overlapping concepts, and create a single, cohesive assessment system that better reflects how interdisciplinary modern Life Sciences and Biotechnology research has become. Previously, a student interested in both research pathways often had to prepare for and sit two separate national exams covering significant common ground. The merger removes that duplication.
If your target cycle is June 2026 or earlier, none of this affects you, your preparation follows the current, well-established format described later on this page.
If you are targeting December 2026 or later, here is the practical reality: your core Life Sciences subject knowledge, the 13-unit syllabus that has always formed the backbone of CSIR NET Life Sciences, carries forward directly into the merged exam. The new syllabus builds on this existing foundation rather than replacing it, adding Biotechnology-specific depth alongside it. This means there is no reason to delay starting your preparation while waiting for the final pattern announcement. Strong fundamentals in molecular biology, genetics, cell biology, biochemistry, and the rest of the core syllabus remain exactly as valuable under the new exam as they were under the old one. What’s genuinely new is that building working familiarity with core Biotechnology application areas, things like recombinant DNA technology, bioprocess engineering, and genetic engineering applications, is now a smart addition to your preparation, since these appear more heavily in DBT-BET’s traditional syllabus and are expected to carry into the merged paper.
We are updating our own coaching structure in step with each official clarification from CSIR-HRDG and NTA, and if you enroll with us targeting the December 2026 cycle or later, we will guide you through exactly how to adapt your preparation as the final details are released, rather than leaving you to interpret notifications on your own.
The CSIR NET (Council of Scientific and Industrial Research, National Eligibility Test), conducted jointly with UGC by the National Testing Agency (NTA) on behalf of CSIR-HRDG, determines eligibility for Junior Research Fellowship (JRF) and Assistant Professor or Lectureship positions in Life Sciences. It is conducted twice a year, generally in June and December, and Life Sciences typically draws the largest applicant pool among CSIR NET’s five subjects (Life Sciences, Chemical Sciences, Physical Sciences, Mathematical Sciences, and Earth Sciences), making it one of India’s most competitive national-level science eligibility exams. This is a genuinely national exam, with candidates and exam centers across every state, not a regional one, and our coaching is built to serve aspirants wherever they are in India, not just students who can travel to Hyderabad.
This is the pattern for the current, pre-merger format, applicable through the June 2026 cycle. As detailed above, this is expected to evolve for the December 2026 cycle once the new joint exam’s official pattern is fully confirmed.
A Master’s degree in Life Sciences or a related discipline (or equivalent), with a minimum of 55% marks for General and EWS candidates, and 50% for OBC-NCL, SC, ST, and PwD candidates. Candidates in their final year of Master’s are also eligible to apply provisionally. For the JRF award specifically, the upper age limit is 30 years as of the first day of the month in which the exam concludes, with a 5-year relaxation for OBC-NCL, SC, ST, PwD, and women candidates. There is no upper age limit for the Lectureship-only eligibility category.
Qualifying for JRF currently carries a monthly stipend of 37,000 rupees for the first two years, which increases to 42,000 rupees per month as Senior Research Fellow (SRF) from the third year onward, in addition to house rent allowance based on the city of posting. These figures were revised upward in recent years, so if you see older, lower figures cited elsewhere, confirm against the current official notification.
CSIR NET Life Sciences cutoffs are reported differently from most other CSIR NET subjects. Because Life Sciences draws by far the largest applicant pool among the five subjects, and the exam runs across multiple shifts, NTA applies an Equipercentile normalization method, which produces cutoffs expressed as high percentile-style figures rather than a simple percentage of the 200 total marks. As a verified reference point, the June 2024 JRF cutoff was 99.08% for Unreserved candidates, 96.52% for EWS, 96.45% for OBC-NCL, 91.79% for SC, 87.82% for ST, and 69.14% for PwD. Lectureship cutoffs are somewhat lower than JRF within each category.
These figures look unusually high compared to other CSIR NET subjects because of the normalization method, not because Life Sciences requires near-perfect raw scores. A cutoff of 99% reflects your normalized percentile standing relative to other Life Sciences candidates that session, not the percentage of questions you personally need to answer correctly. Always check csirnet.nta.ac.in for the current cycle’s exact figures.
Life Sciences is typically the most heavily subscribed of CSIR NET’s five subjects, drawing applicants from a wide range of undergraduate and postgraduate backgrounds including Botany, Zoology, Biotechnology, Microbiology, Biochemistry, and general Life Sciences. This larger applicant pool is part of why Part C, the highest-weightage and most application-focused section, matters disproportionately for a competitive outcome, since it is the section where genuine preparation quality shows most clearly under negative marking.
We specialize exclusively in Life Sciences, which means our faculty, study material, and test series are built specifically around CSIR NET’s actual pattern and syllabus, not adapted from generic multi-subject coaching content. Our faculty bring PhD qualifications and research backgrounds from institutions including IISc, TIFR, and CCMB, with direct experience in how CSIR NET’s Part C application-based questions are actually structured, not just theoretical familiarity with the syllabus.
We put real emphasis on Part A as well, since general aptitude is common across all CSIR NET subjects and is often under-prepared by Life Sciences aspirants who focus disproportionately on Part B and C. And with the December 2026 merger, we are actively building Biotechnology-specific supplementary content into our coaching for aspirants targeting that cycle, so you are not left to figure out the new syllabus additions alone.
Because we teach entirely online in addition to our Hyderabad classroom, students from anywhere in India, not just Telangana or South India, get the same faculty, same study material, and same test series as our in-person students.

Is CSIR NET Life Sciences really merging with DBT BET? Yes. CSIR-HRDG officially confirmed this in notice AB-CSIR0HRDG(OT)/11/2024-Admin-HRDG, dated 13 January 2026. From the December 2026 cycle, CSIR-NET (Life Sciences) and DBT-BET (Biotechnology) are replaced by a single Joint CSIR-UGC-DBT JRF-NET examination. The June 2026 cycle was still conducted under the previous, separate format.
Why are CSIR NET and DBT BET merging? According to the official notice, the goal is to streamline the examination framework, remove redundancy between two exams testing substantially overlapping concepts, and create an assessment system better aligned with how interdisciplinary Life Sciences and Biotechnology research has become.
Will there be fewer JRF seats after the merger? No. CSIR-HRDG has officially clarified that the merger does not reduce the number of available fellowship positions; selection will simply happen through the single combined exam going forward.
Do I need to learn a completely new syllabus for December 2026? No. Your core Life Sciences preparation, the same 13-unit syllabus that has always underpinned CSIR NET, carries forward directly. The merged syllabus adds Biotechnology-specific depth on top of this existing foundation rather than replacing it.
How does the merger affect Biotechnology background candidates specifically? Positively. Under the previous DBT-BET system, Biotechnology candidates had more limited eligibility categories. Under the merged exam, qualifying Biotechnology candidates become eligible for all three categories, JRF and Assistant Professor, Assistant Professor and PhD admission, or PhD admission only, the same breadth previously available only to Life Sciences candidates.
Who conducts CSIR NET? CSIR NET is conducted by the National Testing Agency, on behalf of CSIR-HRDG, jointly with UGC.
What is the current CSIR NET Life Sciences exam pattern? 145 questions across three parts, of which candidates attempt 75, for a total of 200 marks in 3 hours. Part A and B award 2 marks per correct answer with 0.5 negative marking, and Part C awards 4 marks per correct answer with 1 mark negative marking. This applies through the June 2026 cycle; the merged exam’s final pattern is still being confirmed for December 2026.
What is the eligibility for CSIR NET Life Sciences? A Master’s degree in Life Sciences or a related discipline with at least 55% marks for General and EWS candidates, or 50% for OBC-NCL, SC, ST, and PwD candidates. Final year Master’s students can apply provisionally.
What is the current JRF stipend? 37,000 rupees per month for the first two years, rising to 42,000 rupees per month as Senior Research Fellow from the third year, plus house rent allowance based on city of posting.
Is there an age limit for CSIR NET? For JRF eligibility, the upper age limit is 30 years as of the first day of the month the exam concludes, with a 5-year relaxation for OBC-NCL, SC, ST, PwD, and women candidates. There is no upper age limit if you are applying only for Lectureship eligibility.
Do you offer coaching to students outside Hyderabad or South India? Yes. Our online programme is built specifically to serve students anywhere in India with the same live classes, faculty access, study material, and test series as our Hyderabad classroom students.
Do you offer both online and offline coaching for CSIR NET Life Sciences? Yes, offline classroom coaching in Hyderabad at 30,000 rupees, and online coaching at 25,000 rupees, both covering the full syllabus and test series.
How often is CSIR NET conducted? Twice a year, generally in June and December, though exact dates are confirmed in each cycle’s official notification. From December 2026, this becomes the Joint CSIR-UGC-DBT JRF-NET cycle.
