CSIR NET Physical Science Section-wise Analysis

Part A

Candidates largely agreed that Part A was easier than expected. Since this section contributes significantly to the overall score, many believe that students with strong General Aptitude preparation may gain an advantage in the final rankings.

Part B

Part B was considered moderately difficult. Students who had prepared consistently and practiced previous years' questions reported that this section was manageable.

Part C

Part C was viewed as the most challenging section because of its conceptual questions. Rather than testing direct formula application, many questions required candidates to apply multiple concepts together.
