ALEKS

Overview
ALEKS (Assessment and LEarning in Knowledge Spaces) is an online, adaptive artificial intelligence engine that can teach you math from K-12 and through college algebra, trigonometry, precalculus, and statistics. It works by the following method:
 * 1) Asks you a type of problem, e.g. "solving quadratics by factoring."
 * 2) If you get the problem wrong, it thoroughly explains that specific problem and the strategies used to solve it, and then asks you another problem of the same type.
 * 3) Once you get several right in a row, it adds that problem as a "learned topic" to your progress chart and then asks you another question, e.g. "solving quadratics by completing the square."
 * 4) Repeat until complete.

Why is ALEKS important?

 * 1) It is accepted as direct credit for math coursework by all of the Big 3. For Thomas Edison, ALEKS trigonometry fulfills your precalculus requirement for a business degree.
 * 2) You only need to reach 70% to pass -- you don't need to take a whole course, just reach 70% on a periodic assessment test and you are done.
 * 3) It only costs $20 per month -- much cheaper than even a CLEP test.
