Thinkwell's Chemistry is a two-semester college-level course that's accessible enough for introductory college chemistry courses, but rigorous enough for science majors. It is an excellent college prep course but requires a solid foundation in math; Algebra 2 or College Algebra are recommended as a prerequisite.

Calculus is advanced math for the high school student, but it's the starting point for math in the most selective colleges and universities. Thinkwell's Calculus course covers both Calculus I and Calculus II, each of which is a one-semester course in college. If you plan to take the AP Calculus AB or BC exam, you should consider our Calculus for AP courses, which have assessments targeted to the AP exam.Thinkwell's award-winning math professor, Edward Burger, has a gift for explaining and demonstrating the underlying structure of calculus, so that your students will retain what they've learned. It's a great head start for the college-bound math, science, or engineering student.

College Algebra includes hundreds of multimedia video tutorials that provide dozens of hours of instruction from Edward Burger, the best math teacher in the country. His videos give you a more engaging, more effective way to learn.Instead of reading page after page from a printed book, you can watch videos filled with illustrations, examples, and lots of Professor Burger's humor. Students report learning more easily with Thinkwell than with traditional textbooks. In addition to the videos, there more than a thousand exercises with fully worked-out solutions and explanations. Each video topic has corresponding exercises to test your understanding.
