Research-Based Approach

90%+

Pass Rate

Proven Results from Multi-Year Research

The topics covered in these videos were identified through a comprehensive multi-year research study of students enrolled in college algebra and students being tutored for post-secondary high-stakes math tests.

The study found that straightforward explanations of these concepts, along with concrete examples, resulted in a greater than 90% pass rate. Additionally, some students went on to be successful in majors that required several college-level math classes.
