I have personally experienced and also heard from many that the checking pattern in AKTU of semester exams is quite lenient. All you need to do is
Attempt all answers
Write as lengthy answers as you can
These two strategies will help you score good marks. If you come across a question you don’t know the answer to, simply write anything remotely related to the question and you will score some marks. The general idea is the length of the answers over the content. So fill as many sheets as you can and you are good to go.
