Do you need students to come in and take a test. I have often had large numbers of students who come in and need to make up an exam or to retest and during class I get so busy that I forget to remind them. What I do is print these out and fill in names and the make up test date. I will appoint a student to pass these out to the students they belong to. This way they all come in and retest and I don't forget anymore. It is also great for students to have a hard copy reminder that they need to come in instead of just a verbal reminder which, more often than not, just gets forgotten.
