I relate. I've only taken one full test so far. My TS was 16 🙁 (I plan to take another full test two weeks from now).
I have also taken 3 timed Achiever PAT tests and oooh boy did I get my ass whooped on that. on CDP I've been getting 20's fairly consistently. Well, on Achiever PAT I can't seem to get above 17 🙁
