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.

• Sample Midterm 1 (from Fall Quarter 2017)
• Sample Midterm 2 (from Fall Quarter 2017)
• Sample Final Exam (from Fall Quarter 2017)

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.
