Hi there,
So I've taken 5 CAT exams so far, and I've found that I generally have difficulty with my timing on the Quant section. However, my problem is not that I spend too much time on problems that I don't know how to solve, but rather, that I spend too much time on questions that I do know how to solve.
On questions that involve lots of algebra or arithmetic (700+ level), I sometimes make minor errors early on in my calculations, so that the answer that I finally arrive at does not match any of the answer choices. By that point, I've already spent ~2 minutes working on the problem, and I'm left with a dilemma: either to go back and find the error in my work, or to guess an answer and move on. I usually opt for the first option, not only because I know how to solve the problem and want to get it right, but also because I've already spent ~2 minutes on the problem and feel that the time would have been wasted if I just end up guessing. Unfortunately, I sometimes end up spending up to 4 minutes on such problems - and even though I usually get them right, I run out of time on the last 7-8 problems and have to guess strategically. As a result, my Quant percentile score drops by ~10 points (i.e. from high-90s to high-80s) right at the end of the section!
So my question is: what should I do when I find myself in a so-called "silly mistake" situation? Should I go back and find the error and get the question right, or just accept that I've wasted 2 minutes of the test, guess an answer, and move on? (If there is a third, better option, please let me know!)
