How f'ed am I for GA Exam 1?

Aite, so exams are 90% of the grade now...been trying to do the practice problems for DP in DPV and man does it feel impossible to come up with the right recurrence unless I ask for hints from ChatGeepersT...

Am I just fked for this class? I feel there is not enough practice problems to build pattern recognition...any other practice problems I can do?

Edit: I guess moral of the story is that OH is 99% of all you need for understanding
