On the first Linear Algebra exam, I lost two points for an arithmetic error on one problem, and five points for completely misreading another problem. I read the problem as involving the sum of two matrices being equal to a third matrix, while it was actually about the determinants of the matrices. The notation is similar enough to be easily mistaken, with square brackets used around matrices, and vertical bars around the matrix elements (with no brackets) representing the determinant. My score was 93%.
In American Government, I missed four questions out of fifty, but got four of the five bonus questions right, for a score of 50 out of 50. However, the instructor decided that one question didn’t have a correct answer anong the choices, and is dropping that question. I convinced him that there were two valid answers on another question, so he is giving credit for that one. As a result, my actual percentage is over 100%, though I’m not sure that it will count as such in the averaging.
I really need to find time to work on written papers for American Government.
