Begin on time:
Start your work on time and do not waste time on unnecessary things.
Self-assessment: Study-time should be genuinely effective. See if you really studing or frittering away time.
Time-Management:
See that proper time is allotted to each subject and to each part of all the subjects. Do the difficult quesxtions first when more fresh.
Regular Breaks:
Divide and plan the work and allow time for recreation. Rest relieves fatigue, not boredom, so a difficult task may be even more difficult after a break. Time your breaks properly.
