    Hello Friends,  I took RIL written test on 6th April 2008 at Sri Baghwan Mahaveer Jain College , Bangalore

    It comprised of 2 tests:
    1. Mental Ability Test MAT - 75 question in 30 mins
    2. Subject test related to one's engineering. In my case it was Electrical & Electronics - 50 questions in 30 mins

    MAT comprised of very simple question, english and simple maths. Does not need any preparation. All the questions were Multiple Choice Questions except a few in which we had to write the answer.

    All Mental Ability Test was given from previous papers only.
