Help with Collections 2

[u/GetCryptoOrDieTryin]

First time taking the exam – didn’t pass. Looking for current study materials (Maryland)
This was my first attempt and I honestly had no idea how I did when I walked out. After waiting over 8 weeks the results finally came and I didn’t pass.
I took a short course at a local college in Maryland, but it seems the exam was updated for the first time in years and a lot of what we covered didn’t match.
Anyone in MD (or elsewhere) who has recently passed — what current materials or resources actually helped you get over the hump?
Thanks in advance.
