The examinations of the present era are becoming tough nuts to crack with the rise of every Sun on the academic horizon of the world. The tests related to General Mental Ability have also received greater attention of paper-setters. Thus, these tests would be more difficult in test session commencing from 2002 AD. We, at RPH, decided to give an edge to the candidates such examinations. We worked hard for more than a year on the manuscript of this volume. What finally turned out to be, was a systematic and neatly planned compendium, exclusively dedicated to general mental ability tests. Students preparing of entrance test and competitive examination of MBA, CDS, NDA, CAT, MAT, CMAT, RRB, SCRA, SBI-PO, SSC EXAMS, UPSC, GMAT, G-INDOMAT, IBPS-CWE, B.Ed. etc., would find it to be a boon for themselves. This systematic study and practice will help them succeed I their examinations. On behalf of publishers, we wish you all the best for your forth-coming examinations.
