Review every question from your first two exams in detail, and understand how to do each of the problems, and how you could solve it (after reviewing the answer) without re-looking at the answer. You will then get a feel for how you need to tackle the problems
Check the forums for (i think) my super wicked sick pat tutorial. Read through a few pages.
You can google for a site predds, which also has some PAT material.
Between your practice exams, 10 CDP's, that forum and the site above you have more than enough. As you do them, you get faster and will generate a consistent method that works for you. Id strongly recommend reading through the forums to see different strategies for each, and see which of these (or a variant of) works the best for you, and then master it.
Angles - no method or me
Holepunching - used a drawn out box grid and putting my fingers on holes, visualizing the axis and where it would fold, eventually didnt need this anymore
Keyhole - compared heights of different edges, and would look for which edges to compare based on the answer choices. Eliminate obvious wrong ones
TFE- Read the Sick PAT tutorial thread, usually would glance at the sides given in the problem, then glance at the answers, and look for shapes/ edges/ planes i could identify. If i see the font view of the answers contained a hole going through the center, i would look @ the problem top view to analyze for a dotted line through the center running from top to bottom where the hole would be. Then you pick up the nuances like different planes, overlapping edges, etc etc. The more you do, the better youll get.
Folding - compared adjacent sides alot, came with alot of practice
