As AIIMS exam is approaching nearer what should be my strategy to study for that...?

@ kranti 
aiims is focusing upon the concepts,, so, do as much ques as possible ..
do as much mock test as required , and atleast practice upon those area in which u are weak in ..
and at that time keep revising the known topics . 
target the cutoff only , and donot make blind guess as it also contains negative marking ...
