💪 Practice Problems

DSC 10 at UC San Diego

This site contains practice problems taken from old DSC 10 exams. We’ve organized problems in a few ways:

  1. As extra practice problem sets. Each problem set contains problems about a particular topic. Come to extra practice sessions to work on these problem sets in groups, with the help of our course staff.
  2. As practice exams. Work through these in the weeks leading up to exams.
  3. As quizzes. Work through these to practice for quizzes.

In all cases, you should work on these problems on paper, since your exams will also be on paper. Even though you will see some multiple choice bubbles, you intentionally cannot select them.

🧮 Pretest

DSC 10’s only prerequisite is high school algebra. In order to gauge your preparedness for the type of math you’ll see in this class, you should work through these practice problems on your own. You will not submit it, and it will not be graded, but it will help you identify any gaps in your background knowledge and it will teach you some useful test-taking skills.

Starting in Fall 2023, quizzes are administered in discussion section. Below, you’ll find an archive of past quizzes. While you’ll find the answers to all quiz questions, you won’t find detailed explanations. For quizzes, you should try to figure out why the answers are what they are on your own, and come to us in office hours if you’re stuck. (Exam questions are harder, hence the detailed explanations.)
