I would not care too much about the coding part. It was very basic. Try and work on the logical reasoning part. Questions based on English alphabets like A:B::C:? etc. Also, keep a piece of paper handy which has all the numbers for each alphabet. Helps a lot. Secondly, work on those long paragraph inference and deduction questions. Example: A is sitting across the table to B, B besides D....who is opposite C? Or something on similar lines. You get the gist I hope.
