Hard work will get you where you want to go! I started at a 139diagnostic and just scored a 150 on only my third PT with a 165 blind review. It's a slow process, but keep working at it!
Started with a 139diagnostic. 143 first PT after the CC. 169 on my last PT. Just takes time. Took me 14 months to get to this point. Put in the work and it'll come.
