Unit Exam Errors

Bonus! I will pay you one extra unit exam point if you find an error in one of the unit exams. This means an error in the answer to one of the problems on either a practice or proctored exam. However, I will only pay the first person who finds the error (more precisely, anyone who finds an error before it is posted here).

Of course, even if you are not the first to report an error, I will certainly give you back the point if you did the problem correctly on a proctored exam or online homework assignment. I will correct all affected exams, and also all affected homeworks where a correction would make a difference in the grade.

However, I will not check all homeworks. Thus, you should check your old exams and online homeworks against the list of errors below. The reason is that you may have been under the impression that you missed a problem which was actually done correctly after all, and that could affect your understanding of the material.

Errors that have been discovered are listed below on this page (updated Feb. 15).
