hello there,hope you are doing well.let me tell you that you can prepare for CLAT even in 45 days .There is no issue.

But the thing is -try to utilise your time in a best possible way. For standard G.K, you can prefer ‘LUCENT’ and coming to CURRENT AFFAIRS section refer sites like bankers adda,affairs cloud,and some other best sites.Even, you can subscribe magazines like-’Pratiyogita Darpan’.

Well,coming to the most toughest part that most of the people is-REASONING.The books you must  prefer to crack reasoning are R.S.AGGARWAL’s ’ VERBAL AND NON-VERBAL’ and QUANT.

For L.A ,prefer A.P.BHARDWAJ’S LA&LR.
