exam results

Just got the results from my Macro final, the one that I knew I did not do well on, and the grade reflects that fact. The problem was that I was under the impression that one specific model would be theoretical, but he asked a completely mathematical question about the model instead, which I did not review. So basically it is my own damn fault. My friend also suffered the same fate.
But all is not lost! My friend and I will both take the exam for the class again next year and improve our grades. Now that I have learned my lesson that you have to cover all topics from all angles, and you can't play Russian Roulette with what is going to be on the final.
