Golden rules for good marks in VU Exams.

As per my experience, I have developed some golden rules for getting good marks in Virtual University Exams based on experience. I got 3.96 CGPA by following these rules. So here they are:

  1. Never miss your Quiz, Assignment, or GDB.
  2. Always try to do your Assignment on your own.
  3. Try your best to finish your video lectures 10 days before exams.
  4. Try your best to read your handouts twice before exams.
  5. Read forward attempt backward.
  6. Never schedule more than one paper on the same day.
  7. Your most difficult paper should have a gap of 1 or more days.
  8. Toughest paper must be scheduled first.
  9. Read questions forward and attempt backward.
