Should I take another muay thai cl or jiu jitsu?

Okay, so I've been doing kickboxing for 6 months now. And started jiU jitsu 5 weeks ago. I currently go to my kickboxing cl at 4-5 PM, then go to jitsu at 6 PM. Well, there's a muay thai cl at 6 PM so I could change and go to the another stand up cl at 6 PM instead of jiu jitsu cl. The coach for the cl is Forrest Griffin's head coach so it's a good class. I like jiu jitsu, but I'm getting overwhelmed by all the techniques and stuff. What would you do?
