I seem to struggle with picking the right questions especially in RC passaes based on philosophy in general. They seem to be lengthy and as a result require an incredible amount of concentration to go through each and every idea put forward.

Another query regarding no of attempts one should aim at in the VA section. Obviously attempting all questions seems a foolish strategy. Any pointers or statistics which could be provided on the attempt/score/accuracy for this section ?
Previous CAT high percentiler's scores and no of questions attempted would be helpful.
