I thank Mentor Merlin. It is a very good material if anybody planning to prepare for the CBT exam. Although, it was not an exact question from this particular app but indirectly related. The best thing I have to say about this app is the rationale below the question and also the important topics that are mentioned in the explanation. There were a few wrong answers but the positive things are they have mentioned where we get the exact references. I thank you once again….!
