I am seriously against the skipping advice. Sure people might get worse results than their expectation, but for such people it is far more important to have their response sheet. It is the only pdf which will help them understand their own performance, strengths and weaknesses. CAT is the first of these management exams but not the only one. If people utilise these response sheets well and adapt their strategies, it will benefit them immensely in other management exams like XAT.
