Tax professionals, how much time did you put into studying for TCP?

I’m essentially losing all of my PTO in June, so figured now would be the time to use up a week or two cram for an exam. I’m trying to see if I can speed run this one and targeting to sit first week of June (4 weeks from now). I’ve worked in tax for 7+ years, now just do c-corps and ASC 740 stuff, but earlier in my career did some 1040s and flow throughs. How well does work experience translate to the material?

I got an 82 on REG in December, which was my first crack at re-learning how to study since I’ve been out of school, but I gave myself 6 weeks and it was much slower at work, so I could study quite a bit during the days + thanksgiving week. The pass rates seem significantly higher than REG, so just trying to gauge if this is realistic at all.
