It’s time to make a different plan to study a part of your everyday school routine and don't be limited to 'cramming' for exams and tests.
I. Establish a routine
Fix a particular time each day to study a particular portion and stick to it
II. Create a suitable environment
An environment which suits you to study rather than an environment which is standard but not as per your style. Always study with full concentration and do not bother if it reaches to only one or two hours.
III. Set a timetable
To be punctual, a timetable is required so that you can plan to cover all your subjects in an organized way,
IV. Look after yourself
Drink plenty of fluids, especially water, and eat healthy foods. Keep sugary foods to a minimum. Make sure you get enough sleep each night.Regular physical exercise makes you feel great, boosts your energy and helps you relax. So try to keep up regular sporting activities or at least fit in some regular exercise as often as you can.
V. Reward yourself for studying
Do the other things apart from study like talk to your friends, watch movies, play your games etc but try to recall the things what you had studied
VI. Have variety in your study program
Study different subjects each day and do different types of work and revision in each study session.
VII. Don’t lose concentration
Have all the appropriate materials with you before you start a session of study to minimize distractions.
VIII. Recall the things to test yourself
Ask your parents or family members to quiz you on what you have learnt, use draft questions from books, past assessments or major exam papers.
IX. Don't get frustrate at exam time
If you have followed a study routine and have been revising your class work, there should be no need to worry. Try to keep yourself calm, positive and confident.
X. Be in contact with your teachers for guidance
Especially if you're having doubts in the concepts or facing problems while solving the questions or facing trouble in grasping a new concept. They will be happy to help.
Deep breathing exercises at the start and end of each session will also rejuvenate your energy levels. You should also involve yourself in outdoor activity of half an hour or an hour as it always helps.
