QUICK TIPS TO EXCEL IN TESTS
Study in small chunks of focused (concentrated) learning with adequate relaxation.
Avoid feeling of fear about test and feel excited about it.
If you feel nervous, try a "deep breath" exercise by keeping your hand on your belly and breathing for 90 mins to feel relaxed.
Try an MCQ on the topic before the exam.
Think of an alternate career so that you will not feel stressed about the particular exam.
During the test - try a hard problem first and switch to easier when you are stuck / before you really try another hard one.
Blink, shift attention when you get stuck at a question.
Cross check you answers, preferably from back to front, and also your equations, proofs etc.
