In MAKAUT semester exams, will I get marks if I write rubbish or just copy the question in the answer paper?

No, there isn't any university that accepts rubbish answers and neither does MAKAUT give marks if you write poor answers in your semester exams.

My friend also had the same notion and she gave her exams at MAKAUT ver carelessly filling the blank spaces with poor content almost irrelevant to the questions. She ended up failing in that particular subject which further confirmed that MAKAUT does not accept irrelevant answers. However, it's recommended to attempt all questions and write anything vaguely related to the question because sometimes the questions come to be wrong and you end up getting marks just for attempting. 

So you need to denounce the mindset that writing anything in the MAKAUT exams is acceptable and will get you marks nevertheless.
