Remember this for future: you NEVER want to go faster than usual / comfortable on the things that you do know how to do / are good at answering.
You may be faster at SC than the average person - that's fine. But you don't want to make yourself go even faster than appropriate for you, because now you're just giving yourself a chance to make careless mistakes on the things that you do know how to do.
If you find that CR is slower / tougher, then the better strategy is to pick 2-3 CR questions for immediate guesses (particulary in sub-categories that are tougher for you - eg, if you're worst at Evaluate or Role questions, guess quickly on those). Then that gives you a little extra time to spend on other CRs.
In other words, you save time on your
worst question types, not your best ones. :)
Next, the stamina issue - It does sound like you might have tired yourself out leading up to the test. Now you know not to do that next time.
Is flipping all the way to the other end (8am) the best choice for you though? That's fine if you are a morning person, but I'm wondering because you picked the extreme opposite time the first time around. It might be better to look for an 11a or 12p appointment.
(Note: they tend to release 8am appointments first and then add appointments in the later morning / early afternoon timeframe as they see how the site books up. They're just trying to maximize the usage of their facility. So, if you like the idea of a later-morning appointment, you might want to keep checking the site until you find one that opens up, and then you can switch your appointment. Note that they charge $50 to change the existing appointment.)
it sounds like you might have also had some anxiety issues on top of that, too, so you might want to look into this:

As I mentioned last time, you may also want to analyze your most recent MGMAT CATs in order to see whether there are any more detailed weaknesses that you need to address. If so, let me know.
I'm curious about one thing. You said you got "9 out of 12" on IR. The IR scores run from 1 to 8, and unless they've changed something VERY recently, the scores don't correspond exactly to a certain number of questions correct (that is, if you earn a 6 on IR, that doesn't tell you exactly how many you got right). Can you let me know where the "9 out of 12" figure came from? Thanks.
