You should all follow what works for your OWN SELF here. I wrote only 8 IMS SIMCATS, spent a lot of time analysing them, even writing down each of the mistakes I made, and classifying them into silly or conceptual/logical error, and rechecked all previous ones after each test so as not to repeat them. This worked for me and I got a 99.9%le finally.. However if you are a person who would be somewhat worried you have not done enough, then this approach is not for you.. What's important is to take on only how much you can bite, analyse EVERY single test you take, and also gain an inner confidence that you have done enough to deserve a seat in the best institutes of management in the country. All three of these are equally important...
