Drilling and PTs Early On

I'm wondering if anyone has advice on how often one should be doing drills and PTs when early on in their studies. I've been studying for about a month and about to take my second PT and have done one drill. I see some people doing drills every single day. I also hear from people that PTs are valuable later on in your studies rather than too early.

What does drill/PT frequency look like for you, earlier on vs closer to test date? I plan to study for about 6-8 months. Thanks for any input.
