Stay calm and cool, eat and drink a lot water. Sleep well. Study and read the book before exam to refresh memory...Think positive!
First of all you have to fully concentrate on your studies. Leave all activities including computer. Leave the bed early in the morning. Make a time table for different subjects for studies. Less eat and less sleep. I am also student and I hope, these tips would be helpful for every student.
Stop reading atleast 10 minutes before the exam , it does more harm than good for what you all remember.
staying calm is the best tip before any exam, stress will just create more problems and you will end up not achieving as well as you would have with a cool head.
don't ever cram, bad experiences.....but if you absolutely know nothing...talk to teacher, if thats no use definately cram
Don't get too nervous, refresh your memory on the subject the night before. Don't waste too much time on a question you don't understand, move on the next one. Sometimes I find clues to remind myself about the answer to previous questions from other questions.
learn each and every thing before one day of your exam.. get up early in the morning and do some mental exercises and get relaxed before actually appearing for the exams..
Read more and more and understand it. if you have any query , slow with teachers or your friend circle. best of luck.
Get a good night's sleep before you take the exam. Cramming all night will not help you if you are too tire to concentrate!
