PT plateau - help!

Hello! I took the June 2023 LSAT and got a score I'm really happy with, but I am looking to retake in August so I can score a few points higher, which will hopefully put me above the median LSAT for a few of my top schools. I've been taking PTs (both timed and untimed) and reviewing them, however I can't seem to get a score above the mid-160s. Any advice on how to break out of this plateau? I'm not really sure what my next move should be.
