Problems are usually solved quickly when you speak to the marker directly.
Only if you fail to reach an agreement with the marker should you contact me about your mark. In that case, you must make a written request detailing why you believe that you should get marks back, including the specific part of the assignment. Bring it and the entire assignment or midterm to me. For each assignment and test, there is a deadline (listed below) after which remark requests will not be accepted.
If you are just concerned about how you are doing in the course, please drop by and talk to me.
