  The expected median grade for this course is between 2.7 and 2.9. So we were only slight below this mark (that means there may be a very slight "curve" at the end of the term, but you should not depend on this).

The link below will take you to an archive which contains old exams and some solutions for previous quarters. I will not post solutions for exams which do not already have posted solutions, however I will gladly discuss any questions you have during office hours or in class reviews.

Old Exam Archive

Math 120 materials website

A student expecting to get a good grade should work through several (5+) of these old exams before each midterm and before the final. You should treat these as practice tests. Take them yourself without looking up the answers first, and then see how well you did and see what you need to work on.
