Avoid Doubtful Questions :
If you get stuck in any particular question, then don’t waste your time trying to solve, leave it and move to the other question. If you attempt a doubtful question and by chance the answer is not correct then you get a negative mark.
Avoid Stress :
If you get stressed then you will mistakes even in the easy questions. Stress can spoil everything and this will reduce the marks.
Some of you get overexcited after reading the question paper and generally do silly mistakes because of the over confidence. Avoid it.
Practice Sample Papers :
Keep practicing the previous year question papers and mock test papers. If you practice mock test daily, then the chances of negative marking in examination will decrease.
Analyse Your Mock Tests Performance :
Analyse the paper after every test, and see that in which topic you are doing mistakes. Again read the topic and try to improve in next mock test.
Be Focused :
While you are solving one question don’t think about any other question which you might have left or want to attempt later.
Avoid answering questions in last few minutes :
Last minute hustle may increase the chances of mistakes and negative marking.
Make a note of your mistakes :
Make a notebook containing your silly mistakes, what went wrong, unnecessary calculations, time spent on solving the question, etc. Revise this notebook every time before a problem solving session or next mock test.
Follow this and your score will definitely improve.
