What should I do to get 80 % in 1st semester MAIT examination?

Firstly, and foremost, you should try and maintain good attendance records as it is one of the criteria according to which the internal marks are allotted.

Do not skip or bunk classes as you will be marked for attendance. Due to the shortage of attendance, one of my friends scored 67 in one of her subjects and she regretted it later.

Don’t leave any questions in the examinations and tests. Always try and attempt all the questions, even if you don't have any clue, write something about the topic. There have been many instances wherein students score more than what they attempted and expected to score.

Prepare a good presentation during the end-term examinations. Try to follow some of the presentations that you create and you can surely score well over 80 percent for your scorecard.
