User Reviews
Khan Academy is the backbone of our homeschool curriculum. Math instruction from arithmetic through calculus is exceptional. The progress dashboard lets me see exactly where each of my children needs help. The fact that this is free is mind-blowing.
The SAT prep section is genuinely as good as expensive prep courses. I studied exclusively with Khan Academy and improved my score by 200 points. The practice questions are real College Board material. Saved my family thousands compared to a prep course.
