Anmol, the text highlighted in red signals a panic alarm to me. You lost the performance then and there with that time investment. Had you guessed and moved on from that question you would have solved 6-7 other easier questions and also not faced so much anxiety. Not to mention the baggage that you carried forward to the verbal section.anmolsharma wrote: But I got stuck on the 25 question, I took 12 mins for it. and ended up with just 12 mins to complete the test.
You must respect time on the GMAT and let your ego subside. It is not as important to get each and every problem correct as it is to pace well in the exam in order to get towards a competitive score.
Going forward, you must allocate a upper time limit to each question type on your practice tests/drills and strictly adhere to that.
Knowing the content itself is not enough to get a good score. Having said that good concepts of course help improve your timing. So, whenever you are building concepts devote more time to see what different channels exist to solve every problem. But when you practice always have the per question time in mind and respect it.
