Some last-minute revision tips for the IISER 2026 exam are provided here. Before you go into the exam hall, follow these tips:
Do not go on studying new things. It is time to revise what you already know.
Don't start learning new subjects now: Just revise what you already know. Opening a new chapter one day before the exam will only confuse you.
Go through your formula sheets: Keep them simple and short. Physics formulas, Chemistry reactions, and math formulas—just glance through them once in the morning and once at night.
Have your documents ready: All the admit card ID proofs should be in one place. Don't leave it for the morning.
Sleep well the night before: Seriously, this matters more than you think. A tired brain makes silly mistakes even on easy questions.
On exam day, read questions carefully: Sometimes, especially in Physics and Maths, the question looks similar to what you've practised, but there's a small change. That small change makes a big difference in the answer.
Start with your strong subject: Some students like to finish the tough part first, but if you're someone who needs confidence, start with the subject you're most comfortable with.
