## MATH1190.03, Winter 2000Introduction to Sets and Logic

The midterm grades were high. I thought about why, and decided that I still feel the midterm was a fair test of peoples' knowledge of the material covered - to do well, you needed to know the material. In other words, I think people deserved the grades they got, and I have no intention of adjusting them down.

At the same time, there is a danger in having such high midterm grades, namely that people will get a distorted view of their likely final grades, and by the time reality sinks in, it'll be too late to do anything about it. In particular, the rest of the course is much less about learning new language (as the basic objects are already familiar), and involves more sophisticated manipulations of those objects than we have seen already. Put another way, people will likely find the remainder of the course harder. I'll be going more quickly too.

Based on past experience, I do not expect the final grades to be as high as the midterm grades were. If you want to try to predict your final letter grade, a rough way to do so would be to drop 5 points from the midterm grades before converting to percentages. If your midterm was a borderline pass, be warned that you will have to work harder in order to still be passing at the end of the course.

To give an idea of the grade distribution, you may consult the following plot.
