Believe in YourselfThis is the foremost barrier to be crossed for scoring high marks in exams. One needs to believe in his / her

ability to learn, memorize and reproduce what has been learnt. Exams are nothing but the test of our faith, confidence and knowledge.

Follow a Time – TableA well set time table allotting specific durations for studying, sleeping, playing/surfing the net and eating

can help every student a lot. Every above quoted thing has to be done every day. A proper schedule can help a student beat examination stress.

Set Every Day GoalsPreparations should be done every day to excel at the day of exams without depending upon any miracle

capsule to bail you out at the last moment. By setting everyday targets and goals, one can achieve incredible results in terms of efficiency and performance.

Take care of your HealthHealth is wealth. This adage never fails. Only a sound body and sound mind can work effectively towards

achieving any objective. Thus to sum up, healthy body is a mandate for rigorous mental exercise that comes up during examinations.

Practice DailyWe eat daily, we sleep daily, so why not study daily?

Regular practice in every subject will keep students close to a subject. If one avoids any subject for more than three days in a go, he/she is bound to lose interest in it.

PresentationTill now we have discussed the pre-exam tips.

This is a crucial tip while writing the examinations. A systematic and neat display of answers can boost your chances of scoring high.

Time ManagementYou need to manage time not only during

exam preparations, but also at the time of solving the Question paper. Carrying a wrist watch during exams is an excellent way to manage time well. You should also try to save some time at the end of the paper to recheck the answers.

Sleep WellA sound sleep a night before exam helps us

relax and rejuvenates our mind. The tired brain needs and we need to understand the needs of our brain, only then we will be able to make the most out of it especially during examinations.

Relax YourselfThis is last but not the least. Relaxing is

like meditating. When we are relaxed we are the most efficient in reproducing what we have learnt.

These notes will not only facilitate better understanding of concepts, but will also ensure that each and every concept is taken up and every chapter is covered in totality. So go ahead and use these to your advantage... go get the OSWAAL ADVANTAGE!!
