Cracking this exam will be cakewalk if your static gk is good. If not then purchase BHU UET Social science guide ( Arihant publication) and finish it as soon as possible. Download previous year question papers and solve it , many question repeat. Apart from these prepare history ( modern and medieval ) and miscellaneous section from Lucent Gk. If you are good enough in mugging up facts then one month is more than enough time for doing all these things. Static Gk is key of this exam so remember as much as possible. Some question from philosophy and sociology also asked but for that Arihant guide is enough. It's easy and you can crack it with good rank in just 15-20 day preparation (max. 1 month), If either your GK is awesome or you are pretty good in memorizing. Some question from math and 30 question from Language (Hindi or English) has also been asked but they are of basic levels. With a score of 170+ you can get a decent rank (General) . Hope it helps.
