Pls help me what to do at present. I have my bits on 20th. My preparation for bits is running weak. I have started panicking now. BITS is my last hope as there are no hopes i have in IIT& AIEEE.  I have not been able to revise many topics in all PCM. Logical reasoning & English are just away(Nothing done yet). And the main part i have not given a single test till now????!!!!

Pls tell me what shud i do in these 7 days take as many tests as possible or to revise topics??? 

One more thing-  I have heard that bits questions are mainly basic & simple logic based in physics & chemistry??? So, shud i do all the topics which i have read less till now at formulae and basic level?(mainly in chem& physics) I am not mentioning maths becaue i have almost read all maths topics atleast at rd level. PLS HELP. REPLY SOON. Pls experts also help if possible

Tell me one more thing how many tests minimum shud be taken before giving bitsat?????
