CSIR Dec 2019 Question Paper Analysis & Expected Cut-off

CSIR NET Dec 2019 NTA Exam was conducted successfully on 15th Dec 2019. Over 2 lakh people for the first time attempted the CSIR NET Dec 2019 online exam conducted by NTA in subjects like Life science, Chemical science & others. While hard copy question paper was not provided this time, based on a survey by students who attempted the exam – Biotecnika brings you a complete analysis of the CSIR NET Dec 2019 exam in Life sciences.

  • Since the CSIR NET Exam was online this time, those who have given the GATE examination before found it similar to that.
  • The Question and marks distribution was the same as the previous CSIR NET examinations.
  • One can select any of the 3 parts A, B & C and start answering.
  • For each part, the question numbers are provided in the right column, so one can go through all the questions of that part by selecting the question number, Or one can go through the entire paper from the start – there is a different option for that, where the entire question paper is available in a word file.
  • The number of questions attempted, answered, marked for review and answered but marked for review will be shown.
  • One can also check on the instruction page during the examination, if required and can also change their preferred language.
  • The best part about online examination is you can change your answer any time you like before the final submission.
  • There is a warning note if you cross the maximum number of questions needed to be answered for that particular part.
  • So in that case, if suppose you want to amend the previous questions you can easily do so.
  • The system of examination is student-friendly. But you have to get accustomed to the digital countdown because watches are not allowed in the exam hall.

After an in-depth analysis of the question pattern based on the survey – the expected cut-off seems to be in the same range as before i.e., 50% for LS and 55% for JRF in the general category. Relaxation would be as per government rule.

Overall, the difficulty level has significantly gone up and new experiment based analytical questions seem to be dominant in this session’s questionnaire.

CSIR NET Dec 2019 Question Paper Review – Unit wise:

NET has maintained its high standards this time well. With a mixture of direct and analytical questions, Part C was challenging. Part B had direct questions, not much of a twist. The weightage of the units and also the topics varied this time, with more focus on a few units. The below analysis is a memory-based analysis & also from data received via the online survey.

Unit 1 – Questions from the features of different types of DNA were asked, Match the following was asked on various types of vitamins, questions from lipids were also there, numerical from thermodynamics & amino acid-based question was asked. Ramachandran plot was not their this time. Overall Difficulty level- 30%

Unit 2 – From this unit, most of the questions came from parts A, B, C. There were questions based on electric potential, membrane channels, the cytoskeleton, function of each type. There were a number of questions from structure of chromatin. The questions were almost direct. The cell cycle also made it to the list but microbial physiology was dropped out from the question paper this time. Overall Difficulty level- 30%

Unit 3 – There were questions on replication, transcription, and recombination concepts. So far there had been no questions from the promoters of RNA polymerase I and III. For the first time, they asked questions from the promoter recognition complex of RNA Pol III. Overall Difficulty level- 60%

Unit 4 – There were ‘match the column’ questions from host-pathogen interaction of both plant and animal. Questions had also come from cell signaling and their examples and cell communication. The questions were direct and scoring. Overall Difficulty level- 30%

Unit 5 – As per CSIR Dec 2019 Question Paper – questions from this unit were both direct types and complex. Plant developmental biology question was there which was directly from bisporic example. There were in-depth questions from fertilization and amphibian gastrulation. In fact, if we analyze then the question pattern of unit 5 – it has changed as compared to the previous exams. Now the questions are not only asked from the basics but also from the gene pathways and functions. Overall Difficulty level- 70%

Unit 6 – As expected a good number of questions were there from unit-6 this time also. Graphs based analysis from C3 and C4 plants were asked. Match the following from hormone portion and secondary metabolites was asked. Mostly the questions were asked from basics. Overall Difficulty level- 60%

Unit 8 – This time unit 8 questions were not all direct. In fact, the pattern was very different from the general type of questions. The questions were mainly set from sub-topics D, E, H, I, J. Questions had come from the basics of maternal and nuclear inheritance from tetrad types, quantitative and qualitative traits, mutation types. Even this year there was a question from LOD score analysis. Overall Difficulty level- 80%

Unit 9 – There were very few questions from this unit, mostly based on cladistics and animal body plan (characteristics of the phyla). Overall Difficulty level- 30%

Unit 10 – As per CSIR Dec 2019 Question Paper – Unit 10 was more or less scoring with questions from adaptation in birds, niche features, population graphs, species interaction, and diversity. Students should be able to score their net marks from this unit. Overall Difficulty level- 20%

Unit 11 – There were not many questions from unit 11 this time. Hardly 3-4 questions combining parts B and C. Mainly the questions had come from paleontological time, Hardy-Wienberg equation and mating system in animals. Overall Difficulty level- 50%

Unit 12 – Experimental based question on Agrobacterium was there. Question on fermentation procedure was asked in Part B. Question from plant breeding, biodiversity and transgenic animals were also asked. Overall Difficulty level- 20%

Unit 13 – Questions were of mixed type from Unit-13. There were quite scoring questions from Restriction enzymes, FACS, RFLP, Statistical analysis, Electron microscopy. Some tricky questions from ECG and protein gels. Overall Difficulty level – 30%

Overall the CSIR Dec 2019 Question Paper pattern was quite interesting. But also there were some tricky questions. The analytical questions were not of a very standard type. If someone follows the reference books & Study materials of Biotecnika then he/she will be able to answer it properly. The format or the question pattern has changed a lot from the previous year. Question-based on examples, types are there more as compared to analytical or experimental types. Part A questions are also relatively easier as compared to the previous year.

CSIR NET Mission 2020 Batch starts 6th Jan 2020

Suggestion for upcoming CSIR NET June 2020 exam aspirants:

  • It is advised not to go through the whole set of question paper at the start of the exam. Instead, go part by part.
  • 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.

CSIR NET Mission 2020 Batch starts 6th January and here are a few reasons why you must enroll early:

  1. Dec life science net question paper was moderate but NTA set question paper maximum on 2 units that’s ecology and mol bio which is not fare..and question hasn’t that much weightage like Csir …

  2. Very difficult and distant to get to the examination center as NTA chooses those who have computer facilities. Then exam was really tough, for those who have prepared well they should have felt moderate. Upto the CSIR UGC NET standards.
