    What Parents Are Saying. . .
    "Professor Burger breathes life and humor into the dreaded, dry subject of math! (It's so fun to hear my daughters actually giggle during their algebra studies.) We have finished both intermediate and college algebra and have been very pleased with the results; the girls understood and retained much more than they did with our Teaching Textbooks experience. We're looking forward to "American Government" this fall.”
    – Janine P
    "I've used the Thinkwell pre-algebra and algebra courses with my two boys. Since then, we've tried public school and a virtual charter school. All three of us are looking forward to going back to Thinkwell math courses once again! My boys like feeling in control of the content; they can skip over material they already know or go back and review. Professor Edward Burger is a fun speaker! It's not dull and dried out. The explanations are clear and the supporting text is well done. I certainly have told others about the courses."
    – Brighid W
    "Because I was able to visually see the concepts demonstrated, I gained a better understanding. The tests and immediate feedback were a definite plus. Immediately after answering I could go back and study the questions missed and retake the test.””
    – Terri J

    Frequently Asked Questions for Thinkwell's Intermediate Algebra

    How do Thinkwell courses work?

    Your student watches a 5-10 minute online video lesson and then completes the automatically graded exercises for the topic. You'll get instant correct-answer feedback. Then move 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 standard table of contents.

    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.

    What math courses should a student take?

    A typical sequence of secondary math courses completed by a college-bound student is: Grade 6 Math > Grade 7 Math > Grade 8 Math > Algebra 1 > Geometry > Algebra 2 > Precalculus. For students looking to include Calculus as part of their high school curriculum and are able to complete Grade 7 Math in 6th grade, the sequence can be: Grade 7 Math > Prealgebra > Algebra 1 > Geometry > Algebra 2 > Precalculus > Calculus.

    Is Thinkwell’s Intermediate Algebra a college course?

    Most 2-year colleges and some 4-year colleges teach Intermediate Algebra, but it is considered a developmental math course. Four year colleges will not award credit for a developmental math course; typically College Algebra is the lowest credit math course at a 4 -year college.

    Does my student get school credit for Thinkwell’s Intermediate Algebra?

    No, only schools are accredited and Thinkwell is not a school, though many accredited schools use Thinkwell.

    Does Thinkwell Intermediate Algebra meet state standards?

    Since it’s not taught in high school, the state standards don’t apply.

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

    You can extend your subscription for $19.95/month.

    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’s Intermediate Algebra course?

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

    Can I see my grade?

    Thinkwell’s course software tracks everything your student does. When logged in, your student can click "My Grades" to see their progress.

    How are grades calculated?

    The course grade is calculated this way: Chapter Tests 33.3%, Midterm: 33.3%, Final: 33.3%.

    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?

    Most of the exercises are multiple choice and they are graded automatically with correct answer solutions.

    Is Thinkwell's Intermediate Algebra Math built on "continuous review?"

    Thinkwell's Intermediate Algebra is carefully constructed to build on previous knowledge, reinforcing key concepts every step of the way. It is not only a reflection of empirically effective instruction, but also reflects Dr Burger’s philosophies learned over a career of teaching mathematics, emphasizing a solid foundation that addresses why students need to learn certain concepts. Finally, Thinkwell Intermediate Algebra is intentionally designed to work for a wide variety of learning styles.

    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.

    Do I get credits for a Thinkwell course?

    Generally, only schools can award credits, and Thinkwell is not a school. We can provide you with a certificate of completion and a grade report. However, if you’re pursuing credit with a particular school or institution, it might be helpful to know that Thinkwell math courses are accredited by the Western Association of Schools and Colleges (WASC) as a Supplementary Education Program. For California students, Thinkwell is also an approved A-G online publisher.
