while doing RCs in CAT i attempt 3 RCs in which i manage 10 questions and 7-8 correct, is it correct or need to improve??

Hi Swaroop, 80% accuracy is good. It would be great if you can increase the number of attempts. Ideally, if you can attempt all the RCs with 80% accuracy, that should be a very good score.

what is an ideal time for attempting all RCs ,actually i solve 3 rcs in 40-45 minutes..
