Links to old Math 20D exams appear below. The following exams are provided "as is"—exactly as they appeared when administered and without answers. These are **NOT** practice exams. They may differ in form and content from the exams given this term. Working through these old exams may be helpful, but it is not a substitute for reviewing your notes, homework, and keeping up with the class on a daily basis. They are provided so that you can know what exams in this class will look like.

**Important Note:** These exams were given when we used a different book for this course, and the topics were covered in a different order. In particular, Questions 3 and 4 on Sample Midterm 2 are from topics that we will not see until after our second midterm this quarter. Only Questions 4 and 5 on the Sample Final Exam are from topics we will see after our second midterm.
