I would recommend practicing P & E by doing practice exams. It is much easier to learn and remember the rules in context rather than just trying to memorize rules that you aren't familiar with. I did not go to law school in TX either so I can feel your pain. I've done roughly 4-5 past exams in full and plan to do at least one more before exam day. The first two I looked if I didn't remember/know the rule and now I try to force myself to come up with something to write down. You can print exact copies of old exams, complete w/ the 5 lines you will be required to write on, from the TXBLE website. Good luck!
