Struggling to pick up fast choreography.. any tips?

Okay, so I’ve been getting really emotional over this. I just came back from a dance class and I am about to have a quick cry session. lol I am pretty new to dance. I feel like I struggle so much with fast choreography, and I don’t know if it’s just my memory or what. Slow routines? No problem. I can focus on textures and details, and it sticks. But when it’s fast, it’s like my brain can’t keep up, and if I forget one part, I just blank on everything. I try to do different styles like Jazz funk, Hiphop, Afrobeats every week.

Also, I usually do a class after working out, so I don’t know if the exhaustion is affecting my memory too.. Any tips??? Anything I can do to improve my memory and just follow along?? I just want to be 1% better each time
