How to use this IIT JAM solved paper

IIT JAM gives you three hours for 60 questions in three formats — MCQ, MSQ and NAT. Spend the first pass on the 1-mark questions, keep MSQs for when you are sure of every option (there is no partial credit), and leave NAT questions for a calm second pass since they carry no negative marking.

1. Set a timer for the full paper duration and attempt it before opening the solutions.
2. Mark the questions you guessed or skipped, not only the ones you got wrong.
3. Read the solution and the concept behind each marked question, then redo it without looking.
4. Note the topics that repeat. They are the ones worth revising first.
