What Parents Are Saying. . .
"My eldest daughter, now a college freshman, used Thinkwell's Precalculus and AP Calculus. With the help of Professor Ed Burger, she scored a perfect 5 on her AP exam and received full college credit! Ed Burger is humorous and organized. The course is very comprehensive."
– Barbara H
“We ordered a subscription of the Calculus for my son who was to retake the AP Calculus B/C exam after scoring a 3 the first time around. He watched the videos at his leisure, focusing on content that he needed to review. He ended up with a 5 on the AP exam thanks to Thinkwell. We highly recommend them!”
– Rebecca O
“Thinkwell Math is the best product out there for students headed into a math or science field in college. My son used Thinkwell Calculus, took the AP Calculus BC test, and scored a 5, allowing him to go directly into Calculus III in college. He loved Dr. Burger and learned so much from the course! My other children will be using it as well.”
– Linda
”We have used Thinkwell Math for YEARS for the upper level maths and now use it from 6th grade to Calculus BC. Prof. Burger is hilarious and able to clearly teach concepts from the very simple to the absurdly complex. He adds little songs, funny demonstrations, and all kinds of interesting examples to make math fun. My kids who have taken the AP math tests have scored 5's, and Thinkwell has been excellent at preparing them for the tests. We are die-hard Thinkwell Math fans and have been happy to tell anyone looking for a math program to look no further!”
– Diane S.

Frequently Asked Questions for Thinkwell's Prealculus CLEP® Prep

How do Thinkwell courses work?

Your student watches a 5-10 minute online video lesson, completes the automatically graded exercises for the topic with instant correct-answer feedback, then moves on to the next lesson! The courses are self-paced, or you can use the daily lesson plans. Just like a textbook, you can choose where to start and end, or follow the entire course.

When does my 12-month online subscription start?

It starts when you're ready. You can have instant access to your online subscription when you purchase online, or you can purchase now and start later.

Is Thinkwell Precalculus CLEP Prep certified by the College Board®?

The College Board® doesn't certify textbooks or learning materials for CLEP exams. Their website suggests consulting college calculus textbooks for preparation. Thinkwell's Calculus by Dr. Burger has been in use at colleges for years.

Does my student get school credit for Thinkwell Precalculus CLEP Prep®?

No, this course is specifically to prepare for the CLEP exam.

What’s the difference between the Thinkwell Precalculus course and the Precalculus CLEP Prep® version?

Thinkwell's Precalculus CLEP Prep® covers only the material required for the CLEP exam.

What if my student needs access to the course for more than 12 months?

You can purchase extra time in one-month, three-month, and six-month increments.

Can I share access with more than one student?

The courses are designed and licensed to accommodate one student per username and password; additional students need to purchase online access. This allows parents to keep track of each student's progress and grades.

How long does it take to complete Thinkwell Precalculus CLEP Prep®?

The pace of your course is up to you, but most students will schedule one semester.

Can I see my grade?

Thinkwell courses track everything your student does. When logged in, your student can click "My Grades" to see their progress.

How are grades calculated?

Because the course is specifically to prepare for the Precalculus CLEP exam, a final grade is not calculated. Results for all assessments are tracked, however.

What is acceptable performance on the exams?

As a homeschool parent, you decide the level of performance you want your student to achieve; the course does not limit access to topics based on performance on prior topics.

Can I get a transcript?

Yes, there's a final grade report print option in the My Grades section. Contact with any questions.

What if I change my mind and want to do a different math course, can I change?

If you discover that you should be in a different course, contact within one week of purchase and we will move you to the appropriate course.

Can I print the exercises?

Yes, but completing the exercises online provides immediate correct answer feedback and automatic scoring, so we recommend answering the exercises online.

Are exercises multiple choice?

The exercises are multiple choice and they are graded automatically with correct answer solutions.

What is Thinkwell's Refund Policy?

We offer a full refund of 12-month subscription purchases within 14 days of purchase, no questions asked. For Essential Review courses, the refund period is 3 days. Optional printed materials are printed on demand and the sales are final.

How does my school review this course?

Should your school need to review a Thinkwell course for any reason, have the school contact and we can provide them access to a demo site.
