Hey! Kind of in the same boat, and I PM'd a few people on here that had scored 177+. I heard from many people that they had seen score variations before the actual test. So I wouldn't worry too much about it.
Same, hoping for 178+ with 175-177 PTs as of late. Almost identical, but my LR is -0 to -3 and RC -2 to -5. Need to figure out how to address my weak points ASAP
I got my first 170+ last week and thought it was a fluke. I took another PT today and got a 173. You probably won't score a 177 every time, but scores like that don't happen by chance.
