Setting a comprehensive study Plan will aid to achieve their goals without any hitch. The plan must be quite realistic and must be in accordance with the schedule as well as daily needs.
One can divide their study sessions and try to cover the difficult portions before they attempt the simpler ones. Creating a familiarity with the study material will help the students in their studies to a very great extend.
Work on your strong and weak areas quite efficiently by practising mocks and tests.

Good luck!
