GATE Chemistry 2025- Theoretical and Numerical: There will be some differences when a candidate knows about the types of theoretical and numerical questions. According to the previous years, approximately 60-65% of the paper in GATE Chemistry will comprise the theoretical questions while the rest will be comprised of all numerical problems.
The difference between the theory and the numerical problems will be the fact that generally in the theoretical problems, concepts of clarity and recalling are all prominent, while the numerical questions will judge a candidate for his analytical skill and whether he is capable of rapid calculations. Data insights reveal that students, who devote nearly half of their study time to numeric problem-solving, would ensure higher scores in the order of 10-15% as compared to theory-based candidates.
In that manner, a proper balance of study material ensures adequate preparations for both types of questions, and the candidate better prepares to attempt the paper.
