Mihir,
with me, the company I work for had arranged a training course for all our AI candidates.
I suggest you read NBIC, and ASME sections I, IV, V, VIII div1 and IX.
Try a lot of math problems and get used to using the Code (flipping back and forward). If you know what to find where (esp. in what section to look), you are a big step forward (it is an open-book exam).
