After exam some hours is needed to prepare for study of next exam. They also need some rest after exam.
So it is essential to get break between exams.
Honesty is the best policy.
But in some courses it is observed that gap is very high. There are instances of 5 days gap between exam to exam. It is not advisable. The period will become very high and students will loose the concentration also.
So, it is better to have a reasonable gap between exam and exam, not too short or too long.
The gap can be helpful to just brush and polish and fine tune what we studied . It does not go to help those who have not studied but wasted their academic time on other matters and entertainments.
Breaks also help them in developing concentration.Concentration is needed for study.Breaks help in completing the study.Break is essential .Students enrich their knowledge in break.
Service to mankind is service to God.
