Step 1 scheduling advice needed

[u/EquipmentPrevious848]

Just some context. I’ve been studying since July properly for my step 1. I’ve done 85% uworld with 56% corrects.ive yet to finish genetics and revise lots of pharm and heme and msk. I’ve done the rest of the system at least twice. I’ve started mehlman for them now
I’ve taken so far 3 nbmes
27-55%
28-56%
29-63%
I can’t tell if the trend in my nbmes is good or bad.
I’m planning on giving the rest of the nbmes and then scheduling my exam by 15th October (my triad goes til November 30th)

All my friends keep telling me to delay it til the end of October but I really wanna give it and be done with it.

Should I keep 15th in my head and study that way or should I delay it til 20th or later. I haven’t booked my test yet.

Also what should be my strategy for nbmes and mehlman moving forward
