The difference is all in how much you study and how you study. A little bit of time management along with organized and structured studying can go a long way in boosting your confidence to face the exams. Here are some useful guidelines and tips that could help you prepare better for your exams.
Do's
Structure a realistic revision timetable - start with the last exam and work backward
Try and assess how much time you need for each subject - depending on the extent of the subject as well as degree of difficulty - before drawing up a study schedule
After each lesson - note down the important points like dates, names etc that'll help you take a quick glance and refresh your memory during your final revision
Use memory tricks like as acronyms and illustrations to associate to the key words and facts you have to remember
Have a ready-reckoner of formulae, definitions, and key points for essays at a single place for a quick reference just before the examination. This could affect your alertness and concentration levels
Studying in groups could help you exchange notes and clarify doubts
Don'ts
Say 'no' to last minute cramming. Rushing though the lessons won't help in any way!
