Accuracy vs Percentile

You wont get accuracy by leaving questions, try to solve all problems initially and where you go wrong solve such questions more to make your weaknesses redundant, once you do that your confidence will boost miles away. Secondly, give maximum mock tests and make sure you dont repeat same mistakes again. once you're done with that you can then choose and select certain questions in final CAT exam to score great percentile wiyhin less amount of time for maximum accuracy. All the best for future endeavors.

Ensuring accuracy is of utmost importance in CAT. For a section like VARC, it is difficult to ensure a high accuracy since most of the answer options or questions can be tricky. So in case of RC, the more you read, better understanding you will get. While answering, follow your instincts in terms of the context. As far as the English Usage questions are concerned, the accuracy will be dependent on the practice. More you practice, more perfect you will get. Also consult with your mentors to realize where exactly you are going wrong and find out the correct methods. All the best!
