Every student can get certain benefits in case he adheres to the following five tips while preparing for the examination.
1) Read a chapter/lesson/topic thoroughly at least 3-4 times after it is discussed in the class. You may then refer to any notes/suggestion papers. Write down your doubts for help from tutor/teacher. Don't rush to any teacher with doubts before this activity.
2) Prepare your lessons/chapters/topics by writing the answers yourself to questions from the textbook/reference books/last few years examination questions/question bank.
3) Never start reading a new chapter a day before any examination. It will lead you more shaken and confused. Be patient and revise already prepared topics.
4)It is always helpful to read 3-4 hours every day for the entire year rather than 10-12 hours few days before the examination as the human brain is adaptive to absorbing new information and retaining it when it is gradual rather than abrupt.
5) Never inquire about what/how your friends have prepared their lessons on the eve of the examination.
It makes you more uneasy, nervous, add no value and instead impacts your mental balance.
