How to study for ASCP/AMT exam in 4 months?

Hii I'm back. From my previous post I explained that I've been out of lab work for a while, but I want to return back. I do not have my certification (I'm shooting myself in the foot for that, but can't go back in time).

I got an interview for hematology at a hospital, but at my previous lab I worked at post grad, they didn't require ASCP or any other credentials besides successfully graduating with CLS. I worked in micro strictly. I took the ASCP a year after graduation and bombed it (I passed micro well), but I took it without studying. Anyways- I have about 3 months to take this exam because idk how else to get back into this.

Does ANYONE know of any good tips to cram for this? I have my old study books but I'm like...screaming inside. As well as my old powerpoints, however I'm like what even is this? Any encouragement, advice, resources would be awesome!
