What strategy should I follow to crack AFCAT 2013?

Hello sir, i am ashish singh, final year student of nit durgapur. I applied for afcat 2013(indian air force) whose exam is scheduled to be on 24 feb. 2013. I also applied for the same in previous year under ues-2013 but didn't qualified in that exam.this time i am very much desperate to crack the afcat but lacks the proper guidance to get through it. I am good in aptitude and reasoning as i got the job through campus placement in wipro technologies but not interested to join it.
Plaese give your valuable suggestion and guide me to get successful in afcat 2013 and trick for the exam.last year the cut-off was 143 out of 300, that i heard.
I am left with one month, what strategy should i follow in order to come out with flying colours at the end.
