You should be well aware about your HSC syllabus and topics covered in the textbooks. Most of the questions asked in this exam are based on the theories, definitions and concepts based on HSC syllabus. So prepare well and cover all the topics related to that subject.

Solve papers to understand your strong & weak points and strategise accordingly.
Try to formulate tricks for particular type of questions which you find time-consuming because MHT-CET is a test of your speed as well.

Divide your time well among all the subjects. All the subjects all equally important and need full attention to score high in the exam.
