As per students reactions, the CSIR NET 2024 Mathematics paper's overall difficulty level is moderate. Candidates did not face any technical glitches.

Topics asked in the exam 

As per students, topics asked:

Part B same as usual

Q:   Is the CSIR NET exam lengthy?
A:
The length of the CSIR NET exam can vary depending on the subject and the paper you are appearing for. The CSIR NET exam consists of multiple-choice questions (MCQs) and is conducted in two sessions: Part A and Part B/C. Part A is common for all subjects and contains questions related to general Science, aptitude, and reasoning. Part A consists of 20 questions, and the candidates have to attempt 15 questions. Each question carries two marks, and there is negative marking for incorrect answers. Part B contains subject-specific multiple-choice questions, and the number of questions may vary from subject to subject. Part B carries two marks for each correct answer, and there is negative marking for incorrect responses. Part C consists of higher-value questions that test the candidate's knowledge in a particular subject. The questions in Part C are designed to assess the analytical skills and problem-solving ability of the candidates. The total duration of the exam is three hours, and the length of the exam can be considered moderate to lengthy, especially for subjects with a large syllabus. It requires a good amount of preparation and time management to answer all the questions within the given time frame.
Q:   Is there any set pattern of distribution of questions in the CSIR NET exam?
A:

Yes, there is a set pattern of distribution of questions in the CSIR NET exam. The exam pattern may vary slightly depending on the subject, but generally, the distribution of questions is as follows: 1. Part A: This section is common for all subjects and consists of multiple-choice questions (MCQs). It contains 20 questions, and candidates are required to attempt 15 questions. Each question carries two marks, and there is negative marking for incorrect answers. 2. Part B: This section consists of subject-specific multiple-choice questions. The number of questions in Part B may vary depending on the subject. Each question carries two marks, and there is negative marking for incorrect responses. 3. Part C: This section contains higher-value questions that assess the candidate's analytical and problem-solving skills. The number of questions in Part C may vary depending on the subject, but it generally has a lower number of questions compared to Parts A and B. Each question in Part C carries four or five marks. The total duration of the exam is three hours, and candidates must complete all the sections within this timeframe. It is important for candidates to be familiar with the exam pattern and distribution of questions in their chosen subject to plan their time and preparation effectively.

Q:   How many questions are there in each part of the CSIR NET exam?
A:

The number of questions in each part of the CSIR NET (Council of Scientific and Industrial Research National Eligibility Test) exam varies depending on the subject. For subjects such as Life Sciences, Chemical Sciences, Earth Sciences, and Mathematical Sciences, Part A comprises 20 questions, Part B comprises 40 questions, and Part C comprises 60 questions. For subjects such as Physical Sciences, Part A comprises 20 questions, Part B comprises 25 questions, and Part C comprises 30 questions. It's important to note that each question carries a specific weightage, which is mentioned in the question paper. Part A carries 20 marks (each question carrying 1 mark), Part B carries 40 marks (each question carrying 2 marks), and Part C carries 120 marks (each question carrying 2 or 4 marks). Therefore, it's essential to attempt all the questions carefully, as each question carries a certain weightage, and a wrong answer can lead to negative marking.

Part A is easy as compared to the previous year

  • Uniform conversion
  • Complex integration
  • Linear Algebra
  • Analytic function
  • Complex analysis a bit hard

Questions asked:

  • Complex Analysis (9 to 8 Questions asked)
  • Linear Algebra (10-15 Questions asked)
  • Real Analysis (15 to 16 Questions asked)
  • Ordinary Differential Equation (5 to 6 Question asked)
  • Modern Algebra (7 to 8 Questions asked), etc.
