Student FAQ
Q: Will WebAssign be required in my Calculus section?
A: Whether WebAssign is required depends on your section. Check your syllabus or contact your instructor for confirmation.
Q: Can I use WebAssign if it is not required in my Calculus section?
A: Yes, you can use WebAssign for practice, but this will not be counted towards the assessment portion of your course.
Note: If WebAssign is required for your section, your instructor will provide a specific class key. Do not use the bootcamp class key or a class key from another section.
Q: I have a copy of the book, but not a WebAssign access code. What do I do?
A: You can enroll in WebAssign without a code during the two-week grace period. After that, you’ll need to purchase an access code to continue. If you plan to take multiple calculus courses, consider Cengage Unlimited, which provides multi-term access for all your Columbia Calculus courses.
Q: How much does WebAssign cost?
A: Up to date prices can be found here. If you’re taking more than one course, the best option is Cengage Unlimited. It includes:
- Multi-term WebAssign access
- All Cengage textbooks (some used in other Columbia courses)
This one-time purchase covers all your Columbia Calculus courses.
Note: Purchase your access code only after enrolling in a WebAssign class (the first two weeks are free).
Keep in mind the following:
- Calculus Bootcamp is free during the access period (see above).
- If purchasing access, select “Buy Cengage Unlimited” for multi-term use, even if not explicitly mentioned on the registration page.
- The department does not offer financial aid for WebAssign.
