Last year's exam as a study technique.

The professor reviewed seven problems on Thursday from last year's exam in Thursday's lecture. I reviewed these solutions today. I then solved another 6 problems on my own this morning and had some difficulties with three problems. I think I will use her review structure also from Thursday's lecture to rewrite my own course summary today. I will also try to solve another 6 problems. But right now I am going to sleep having not slept since Friday morning.
