hi,

for general knowledge I suggest you to read bankers adda and any good gk book of banking exam, also you may brush up your knowledge of science subjects of 10th course for static gk problems. see only two or three week preparation you can not crack any exam with good score and ranking, since covid 19 many of the exams is delayed and it left quite a good time for preparation. I suggest you to follow iim ipmat exam books which has good number of questions,

IIM IPMAT Preparation Guide by Stalwart Career Institute

also you may follow disha experts books on quantitative, reasoning test.
