Lurk, what type of sections were the two that you bombed? Were they both the same type?
And more importantly, where were the questions that you missed within the section?
If you're finding that you're missing a handful of questions early in the section, then it may well be that you're simply not awake yet and that you need to do some warm up problems before the exam to prepare yourself.
However, if the questions you're missing are from the later part of the section, it might be a pacing and prioritizing issue. Rather than worrying about practice sets early in the morning, I would take a few minutes before your next preptest to run through your goals and pacing strategies. Go through each section and ask yourself:
1. How many questions am I trying to get right in this section?
2. Where am I most likely to find those questions?
3. How many questions can I afford to guess on?
4. How often will I allow myself to skip a question the first time through and return to it once I've answered all the easier ones?
These are questions that, in my experience, start occurring to people a section or two into the exam. By then, however, you might have already damaged your score. So instead, start with these.
That's just a general suggestion based on the assumption that the sections you're bombing vary and that you aren't just missing the first handful that you attempt. If you give me a little more information, I'd be happy to follow up with some more focused strategies that might help you out.
Either way, it sounds like you're getting some pretty impressive scores as it stands, so congrats on that!
Take care,
