CDP alone has landed many people with fine PAT scores. CDP is relatively unique in that it can save tests and track the time spent per Q. I'm going to list a few suggestions. I would go back thru your first three tests and figure out how your time per section is fluctuating compared to your score. I highly suggest watching the problem solving videos for TFE/PF/KH and any other problem you get wrong. Use this as an opportunity to work the problem again and compare it to what you thought the first time, then view the video, and just compare thought processes while hopefully integrating some new strategies. CDP has the option to work only on Pattern folding section and set the time to anything you want. Try beginning the test with different sections.
The way I maximized the software goes something like this: (1) simultaneously worked the generators and watched a tutorial vid or two the first two weeks (~2months prep for me) (2) Take PAT test and close the software (3) open up that first test 3-4 days later when just starting out but when you get to around tests 8-10 you can decrease the time to 1-3 days. The reasoning behind this is because your brain is on cooldown. Think DBZ, as a saiyan when you get beat up you will come back stronger. (4) Rev test but also use it as an opportunity to see if your problem solving approach changes - this process was long for me (2 hrs sometimes) and the girls voice is annoying. Use that as motivation to learn. (6) 5-6 days later I would pick a section that I did the worst on for the first test I did and only do that section timed (this was TFE until one day it just clicked and became my BEST section). (7) test 3 I realized time was killing me and I wasn't getting the opportunity to see if I actually could answer everything. So what I did was I just worked through till I answered everything ignoring time. CDP yaps at you but just pretend like the pop up boxes aren't there.
To summarize that, my suggested approach would be to go with what your gut is hinting at: make sure you can actually answer the problems, and THEN, budget your time effectively. Notice in my strat, I didn't care about time on test 3 because if I did, I wouldn't know if I had the ability to do certain problems or not. I wouldn't suggest doing all the tests this way, but its the why behind how you use the software that will matter. GL
Also, you may find some humor in this, but try assinging R/S to a dice problem and see if it will help you solve it faster.
edit: keep in mind that bootcamp and qvault both have a free PAT test available. I used those to my advantage about 2 weeks out from exam time
