It sounds as though you are doing pretty well in practice, db8. If you are aiming for a 700-level score, you should target at least 90 percent accuracy on Easy questions, 80 percent on Medium questions, and, believe it or not, roughly two-thirds on Hard questions. In short, the exam punishes mistakes on lower-level questions more severely than it rewards correct responses to difficult questions, so your goal is to make sure you are diminishing the chances of answering incorrectly on anything other than a 700-level question. If you are at 70 percent accuracy right now on Medium questions, then you seem to be all right, nothing a little fine-tuning could not fix. If you are clueless as to what went wrong, though, then you need to address the issue and figure out how to disprove incorrect answers. Look up the questions in the forum and pay attention to responses that Experts and community members provide on the wrong answer choices. If you simply look to justify the correct answer, you will not really learn much from the question; if you take the time to disqualify other answer choices, though, you will start to figure out different patterns to watch for in other questions, and your accuracy will rise accordingly.

I would stick to Medium-level questions if I were you. Do not be afraid to consult the Manhattan guide again on a topic you miss in some question you may come across. A guidebook is not something that most people can internalize on the first read-through, but if you can make the points stick by applying them to actual questions, especially those you have missed, then you will get everything you can out of both the guide and yourself.

Good luck.
