5 questions on reading comprehension
5 questions on bar chart
rest were mathematical & logical reasoning.

I had attempted 88 in Ist section & 43 in 2nd section. I had cleared the written test and got a call for GD & interview on 9th july at PMI, Noida. the interview were going on since 1st june. I could not clear the interview round. But i will try next time.
