How to get into mma as a beginner?

i started mma a couple weeks ago to try and improve my grappling and ground work etc, but i'm finding it a bit hard to keep up with the class. the instructor demonstrates a series of moves (a reverse guillotine for example) and then we pair up and have to do it. i find it pretty hard to remember what to do because its all pretty new to me and the instructor is usually too busy to help me out. i assume i'll get it in the end but is there any way i can practice the moves outside the class so i'm a bit more prepared when it comes to it? i'm up for trying anything really i just want to learn the specific movements.
