Exam , Grades, Future ..

got my grades for the Artificial Intelligence Planing course , I took this course on last semester and the exam was taken last Saturday when it was snowing heavily outside.  I am surprised at my capability of getting such a poor grade , so far this is the least grade I ever got for any course, hahaa , don't know what's on my future.  Seems like AI is not for me after all. Before working on artificial intelligence, I need to improve my own natural intelligence at the first place.
