CSIR NET June 2021 Question Paper Review – Unit wise

General Aptitude: 

Most questions are from the previous year’s CSIR Question Papers from all disciplines. Quite easy and straightforward questions, which can be answered with just a little bit of preparation.

Overall Difficulty Level – 30-40%

Unit 1 –

Breakdown of Questions – 14 questions (5 Part B + 9 Part C)

  • All types of questions(concept-based, numerical, graph/plot based) from all topics of enzymes(kinetics, inhibition) were in abundance this time. 
  • 2nd most asked topic was amino acids, proteins, starting from properties, secondary structure, denaturation, techniques to study (like chromatographic separation, CD spectra etc). 
  • Questions from otherwise common topics like stabilizing interactions in macromolecules, pH buffer, thermodynamics, carbohydrates, Nucleic acids, and entire metabolism were completely missing this time.

Overall Difficulty Level – 50%

Unit 2 –

Breakdown of Questions – 10 questions (3 Part B and 7 Part C)

  • Easy and direct questions came in Part B
  • However, Part C was unexpectedly tough this time except for 1 question.
  • Normally inhibitor related questions are easy and direct but this time, the reality was different. Actin inhibitors related question came which requires a detailed study about all the inhibitors.
  • Cell cycle related questions were asked which were tough to answer, confusing statements especially related to RhoGTPases and cohesin.

Overall Difficulty Level – 70 %

Unit 3 –

Breakdown of Questions – 9 questions (5 Part B and 4 Part C )

  • As expected to be in the approximate range of 8 – 12, 9 questions were asked from unit 3, 5 part B questions and 4 part C questions. 
  • The difficulty level was moderate as most of the questions were direct questions like those based on DNA repair mechanisms, Rho-dependent and independent transcription termination in bacteria or initiation of replication whereas only a few were indirect. 
  • This time an ample number of questions appeared from DNA replication alone both in part B and part C.
  • 2 questions were framed from the fusion of unit 3 and unit 2 concept, cell cycle as always expected.
  • Lytic and lysogenic cycle, RNA i were the other topics from where questions had appeared. 
  • Surprisingly translation and Operons had been ignored 

Overall Difficulty Level – 50 %

Unit 4 –

Breakdown of Questions – 11 questions (5 Part B and 6 Part C)

  • Easy and direct questions from Cell signalling, cancer. 
  • As expected always match the following from cellular communication(medium).

  • As always one question came related to the causative agent.

Overall Difficulty Level – 50 % 

Unit 5

Breakdown of Questions – 10 questions ( 5 Part B + 5 Part C)

  • Questions from this unit were both direct(straightforward) and conceptual (transplantation experiment-based questions). As expected, questions were asked from early development, gastrulation, and axis formation of Sea Urchins, Amphibians, and Drosophila.

Overall Difficulty Level – 60%

Unit 7 – 

Breakdown of Questions – 8 questions- (3 Part B + 5 Part C)

  • Among the 5 part C questions asked, 3 were from respiration and others from endocrinology. 
  • This time most questions were asked from endocrinology, respiration and excretory systems. 
  • To our surprise, no questions were asked from the cardiovascular system, ECG, probably because in the last exam questions from this topic were asked. Even none of the questions were asked from the Nervous system, so in the next exam, we must expect questions from these topics. 
  • The questions asked are graph-based, statement-based, many questions were easy and can be solved with good preparation, except 2-3 which were difficult.

Overall Difficulty Level – 50%.

Unit 8 – 

Breakdown of Questions – 8 (4 Part B + 4 Part C)

  • 4 part B questions were there which were quite direct. It tested the concept of quantitative trait and qualitative trait, the principle of gene mapping by transformation, imprinting and the concept of penetrance and expressivity. 
  • There was 1 question that was linked with statistics under unit 13.
  • 4 part C questions from concepts like linkage and marker, Pedigree and marker, quantitative trait and complementation group. 
  • The questions were not direct and difficult.
  • All 8 questions were time-consuming and tested for the candidate’s IQ.

CSIR June 2021 Cutoff Expected 

According to the general consensus of the Biotecnika CSIR NET Experts – the CSIR June 2021 Cutoff will be high with 55.8%, 98.99 percentile for JRF(UR), 51.1%, 97.68 percentile for Lectureship (UR)


Overall the CSIR June 2021 Question Paper pattern was analytical and skill-based and needed a lot of in-depth knowledge of the subject. The analytical or logical questions needed a thorough understanding of the concepts, some questions did seem difficult and time-consuming. The format or the types of questions asked from units has gone through some changes. General Aptitude questions were easy and straightforward.

Suggestion for upcoming CSIR NET June 2021 exam aspirants:

  • It is advised not to go through the whole set of question papers at the start of the exam. Instead, go part by part.
  • Make the time distribution as(30 min for part A,1 Hr for part B, and 1.5 Hr for part C
  • Even when you have selected a part, do not sit, and first, select the questions and then start answering. This was a common trend when it was an offline examination. But in this pattern, this approach will only kill time.
  • Instead, start answering those questions which you are confident about. Since you can change the answer anytime there is no tension of marking the wrong one.
  • So select your Part – advisable to start from Part C as it requires more time.
