Hello Aspirant,

If you want to get good score around 300,I suggest you to try to attempt every question.But negative marking will cost you 5 marks so if you want good score you have to attempt 80 to 90 questions.So if your 4 to 5 questions goes wrong your score s till will be near 300.And don't attempt the question thet you don't know the answer 'cause if it goes wrong you'll loose your marks.

I hope that'll help you.
