RCIS Exam Coming Up

To start, I have looked through a bunch of older posts here ranging from 4-5 months ago all the way to about 5 or 6 years. I have the RCIS coming up was told (and also saw here) that Glowacki and Sommers was one of the best review materials. I ordered it, went through it quite a few times, took some notes and researched some stuff outside of the review book that I felt I maybe needed a further explanation to.

So, with that being said I have about 3 years CCL experience, very minimal EP experience, but I tend to scrub as much as possible as well as monitor. We do high risk PCI, CTO (occasionally), and quite a few different structural heart procedures in our lab. Aside from Glowacki and general knowledge from working in the lab would there be any other materials that I should really study? I'm not an RN so I took a good portion of our drugs in the lab and made sure to know those pretty well. The limited equations in the review book are understood and I feel comfortable with them. Is there anything that I may be missing or not covering with just using this review material?

Thanks for any new info on yet another RCIS question!

EDIT: Officially passed the RCIS! Anyone with the test upcoming or looking to schedule please feel free to reach out. between the answers and discussion here as well as other posts it seems mostly everyone was all on the same page regarding material!
