What helped me the most was trying to up my pace on the early part of the LR section. Once I learned that the early half of LR was typically far easier, I gained a degree of confidence that translated to decisiveness which helped me avoid dwelling on Qs or waffling between ACs. The ability to put in a second round of review usually saves me from about 2 incorrect ACs per section. Watching the real-time videos JY posts for PTs >~75 is a perfect exhibition of this technique.

If you're still pressed for time at the backend, there's usually a PF Q that will certainly demand ~2 mins, so I'd avoid skipping that altogether and finishing the remainder before attacking that one. The key, imo, is to know when to cut losses while also sequestering any confusion or indecision from Q to Q; don't linger and don't carry any indecision into the next Qs, especially if you skip around. It doesn't hurt if you can average 35-45 seconds for the early layups either!
