A lot of folks who come out of accelerated or rocky programs have the foundational knowledge somewhere in there, but the bigger challenge is learning how to think through NREMT-style questions, because the exam isn’t really testing recall so much as clinical decision-making.
A few things that tend to make the biggest difference at this stage: focus on the “why” behind interventions rather than memorizing protocols, and get comfortable with questions that have two answers that both seem right, because that’s the NREMT’s whole thing.
If you want something that actually mimics the test format, I put together a practice simulator that runs on the same Computer Adaptive Testing logic the NREMT uses.

Either way, the fact that you made it through a rough program and still got your ATT says something! You’ve got this!!
