Dear Sir/ Madam, Thank you for posting you query at healthcaremagic.com I advice you to study at relax mode. Do not take your study as a stress. Always study a subject with the fun. It is better to understand the topic well and correlate in practical. Exchange your thoughts and answers with your freind or colligue, this will boost your confidence. Proper sleep is also very important. Avoid continuous study at strech. Swim,talking to friend, stroll, recreational break in between will help. Vitamin E rich diet, protein rich, fish diet are advisable. if you have any further query please revert back to me. Your reply with thank you note will be very much appreciated!! With best wishes Tehzib Saiyed(PT)
