1. Maintain a POSITIVE ATTITUDE towards your study and exams so that you can develop interest in your books.
2. Be prepared always by studying on daily and weekly basis
3. Make a schedule of rest and relaxation periods in between the study hours to refresh your mind because too much over loading will harm your memory.
4. Get rid of all sorts of problems before you start studying so that you can focus on your syllabus only for example finish your visits to the tailor, parlor, friends etc.5. Give balanced time to all subjects.Do not spend too much time on one neglecting others.
6. Preparation for exam is like preparation for a marathon. You have to prepare and practice it long before time . an athlete cannot win the race if he has not run a mile frequently. similarly one who has not studied regularly can not get good grades by studying in the last moments.
7. Take a lot of care for your health. eat balanced diet. take meals in time, fresh juices for refreshments avoid all sorts of junk foods if you want to stay healthy and fresh throughout your exams.
GOOD LUCK
