PE recruiting courses?

Anyone here bought a PE recruiting course or done a program like WSO mentors or OfficeHours?

I’m looking to do something because my group doesn’t model much and I need some help in learning it all. Not the best bank group so don’t want to have any weak points if I do get an interview. I have a collection of old materials from other analysts (ie some old modeling tests, a few guides, etc) but find it hard to study without a structured program and would love some instructional videos or someone to talk me through it.

A couple hundred bucks is worth it to me, I’m making plenty now and would rather spend a few hundred now to make a few hundred k later, so not looking for anyone to tell me they’re all a waste, just if anyone can recommend specific programs/courses that worked well for you. I’ve considered WSO, Wall Street prep, and a few others, so really just looking for any thoughts/experiences on any of them.
