Hello

Yes, you can of course leave the questions whose answers you don't or if you are not sure about the correct answer. There's no compulsion to attempt all the questions . It's just that in section A, one can attempt all the 35 questions , while for section B, there's internal choice i. e you have to attempt a maximum of only 10 questions out of the 15 questions.
In both section A and B, you should attempt only those questions whose answers you know, because for each wrong answer, your 1 mark will be deducted.
