Not doing well in training for BB at all, am I fucked on the desk?

Hey guys just looking to calm my anxiety I guess. I have never interned in IB and did not major in finance, and our instructor/professor goes wicked fast and doesn't really stop for questions. I am having a lot of trouble grasping the material, and I performed pretty horribly on every exam we have gotten, accounting, valuation, modeling, etc. Does this directly translate to me probably being fucked on the desk once I start? I know it varies per group/bank, but if I am in coverage will I get thrown into a bunch of complex technical work as soon as I start?  I am trying my best after training to learn stuff on my own and study on my own, but tbh for me it is a LOT of content and am feeling very pressured. This is for FT BB if it matters. 

Thank you guys
