2. Exam Overview for IIT JAM Biotechnology
2.1 Exam Format & Sections
The IIT JAM Biotechnology exam spans three hours (180 minutes) and is conducted online. Typically, the paper includes three sections:
- Section A: Multiple Choice Questions (MCQs) – four or five options, single correct.
- Section B: Multiple Select Questions (MSQs) – more than one correct answer.
- Section C: Numerical Answer Type (NAT) – direct numeric response.
Total questions usually number around 60, carrying a total of 100 marks. The structure remains consistent across recent years, although small shifts can happen. Understanding this layout helps you manage time and approach each question-type strategically.
2.2 Marking Scheme & Duration
- MCQs: +1 for correct, −⅓ for wrong
- MSQs: +2 for all correct, 0 for partial/wrong responses
- NAT: +1 for correct, no negative marking
Chandu Biology Classes consistently train students to maximize scores, especially in Sections B and C with zero negative marking zones.

- Translation: Ribosome structure, tRNA, initiation and elongation factors, post-translational modifications.
- Gene Regulation: Operons (lac and trp), chromatin regulation, transcriptional silencers/enhancers.
Students are taught to master these topics through pathway illustrations and sequence-based MCQs, a trademark strategy of Chandu Biology Classes that brings clarity and pattern recognition during exams.
4.5 Microbiology: Microbes, Growth, Control
Microbiology has increased in importance in recent JAM exams. Chandu Biology Classes addresses this with a clinical and experimental approach.
