@"Lil Broomstick" You can skip ahead and do PT84 as long as you still have plenty of other PTs. There's nothing special about 84, in the same way that there's nothing special about any particular PT.
Unfortunately those blind review sessions aren't recorded. I have no idea when the explanations for PT84 will be released, but my guess is before the September exam.
I must be a weirdo cuz I actually found PT 72 to be okay for me lol. My lowest score after finishing CC was from PT 60 (I went 6 points lower than my average), but I also feel PT84 (aka June 2018) had one of the hardest LR.
yeah my PT84 dropped too :| which makes me severely nervous about the real test haha; but just remember, we just need to learn from our mistakes! we can totally do it this saturday!
I just took PT84 as well and it turned out to be my worst too. I had the most trouble on its RC. I hope it was just an off day for us or the exam was hard in general!
