Retake related advice

Thanks a lot GMATNinja, it has kinda cleared my dilemma regarding going for a retake..

You're not giving me any good reason to worry about your quant, Heseraj! The MGMAT quant tests are a wonderful challenge, but the quant questions contain about twice as many words -- and probably 50% more steps -- than official questions of comparable difficulty. So if you're struggling to understand what those questions are even asking, you're not alone, and it makes sense that you'd underperform on them.

But you said the magic words:
So I'm not too worried about you. On those MGMAT tests, just make sure that you're developing good habits: don't let yourself get TOO stuck on any one question, and make sure you're not making silly errors on the stuff you understand. But if you can sustain that ~48 on your GMATPreps, that's what really matters.

Everybody is different in terms of which tests they find useful, but I tend to steer people away from non-official verbal tests, just because it's so impossibly difficult for test-prep companies to make them realistic. The quant sections might not be realistic, either, but they're still good practice. It sound like you've held onto lots of good, official material for verbal, so you might not really need to do any non-official CATs for verbal.

I hope this helps, and please tag me whenever you do your debrief in September! You're clearly working your butt off, and I'm excited to see where you end up.
