How many hours in total (reading frame structures etc) + practice is recommended to get good at case studies?
I ask this because even though I have time-someone at my college practiced too much and was burnt out by the time he had interviews. I dont want this to ruin my passion for problem solving and cases (which I seem to enjoy from what I have seen-not practiced)
Also, when practicing case studies by yourself how long does it take to do one case? Should I try to do one over full 30 minutes or just quickly go over it?
