Don't know actually how to implement the time management strategy. i have read that these many questions to be completed by this much time in any section to complete that section, but while doing so if i am stuck in one or two and simply mark and move then those two will also get wrong. what to do with this?
Yes, mistakes aren't good for your score, so what you pointed out is definitely a problem. But getting a bunch of questions wrong in a row at the end is usually a bigger problem.
You should also think about how deep you want to go in any one specific question. For example, let's say that we go over 2 min on a CR question, maybe 3-5 minutes. At that point, we still don't know whether we're going to mark the right answer, so maybe the extra time spent on that question could have helped us on some other (easier) question.
