Preparing for the IIT-JEE exam can be a stressful experience, but managing stress during the actual exam is equally important. Here are some tips on how to manage stress during the IIT-JEE exam:

1. Practice mindfulness: Mindfulness can help you stay calm and focused during the exam. Take a few deep breaths and clear your mind before starting the exam.
2. Time management: Proper time management can help reduce stress. Make a schedule for the exam and stick to it. Do not spend too much time on one question. Move on if you get stuck and come back later.
3. Positive self-talk: Positive self-talk can help you stay motivated and focused during the exam. Tell yourself that you are capable of doing well and that you have prepared well for the exam.
4. Exercise: Exercise can help reduce stress and improve focus. Take a quick walk or do some stretches during the break.
5. Eat well: Eating healthy food can help you stay focused and energized during the exam. Avoid sugary and fatty foods that can cause a crash.
6. Stay hydrated: Drink plenty of water to stay hydrated. Dehydration can cause fatigue and affect your performance.
7. Take breaks: Take short breaks during the exam to rest your mind and reduce stress. Do not spend the entire time staring at the screen.
8. Stay positive: Finally, remember to stay positive throughout the exam. Even if you encounter a difficult question, do not panic. Stay calm and approach the question logically.
