Study resources for C/P?

I’m 5.5 months out from my exam (working full time so I need more study time) so I assume I shouldn’t start doing UWorld yet. I’ve been reading Kaplan for C/P and doing the problems in there, but unsure what else I can do to practice. There aren’t a lot of practice problems so I feel like I’m not studying thoroughly and mastering the material. Anki doesn’t seem as helpful since practice is required, not just memorization. Any resources people recommend? When do you think I can start UWorld? I’m worried about running out of practice questions
