My percentile was 99.95
I joined TIME Aimcat series and that was not very useful. I took very few of the tests. Most of my preparation was passive. I would read The Hindu editorial and the Time.com website. Did not prepare at all for DI or QA. Just went and took the exam with a clear mind is all. So if you need hardcore preparation then I probably am utterly useless for advice on that. I will just say this the Time classes are mostly not very useful, at least what I heard from people. I can't say about the rest as I did not attend them or hear much about them, but I am guessing they are pretty similar too.
I also joined the Time classes for GD PI prep. They gave some good funda on eco and current affairs and you get a decent idea of how a GD goes. But again I went for only 30% of the whole program as I wanted to do my own preparation, my way. At the end of the day, the preparation has to be your own.
You could look at Arun Sharma's books for DI and QA. One of my friends, an IIML passout, prepared using that and he says they are pretty good.
Also thanks everyone and I will come over to Bangy once before I join. So your treat will have to be then I guess.
