So, my first law school exam is behind me. If I had to guess, I'd guess it merited a B+. Given the nature of my graduating class, and the limited number of A's allowed by the curve, I would consider that reasonable, and a success.
Key lesson for next quarter: the Examples and Explanations books are the only study aid worth using - commercial outlines may conflict with what is presented in class, and even the civil procedure BarBri lectures were less useful than I hoped.
Law schools during final exams are an interesting environment: at the risk of over-dramatizing you can almost smell the fear, which is saying a lot given that I don't even have a sense of smell :)
