Test will be simple they have given the pattern on the Web site
english, math ,analytical GAT general by Doggers is enough
for other things like current affairs, and general knowledge you have to consult WHO is who, 1 paper book (Carvan), although for these two portion you need to do more by reading news papers, television and other such kind of things because these things change every passing day,,

for the IQ portion ISSB books are enough...

Good luck
