Hopefully I'm not off base here, but if you neeeeed a 174 I would push it off until November. I got a 174 two times, and my highest PT was a 175 and my lower ones were 168 - 171, I think. Basically, the range of your PT scores are pretty indicative of what your true score is going to be. Since your PT scores are so good already, I think the extra month of studying could get you to 174. I would just blind review and find the concepts that you need to dial in on to close the gap.

It's also a mind game, so going in feeling super prepared can go a long way. I pushed my tests back a month for each so that I could feel confident, and I think it paid off. Good luck!!!
