After Khan Academy announced that they were taking down their MCAT course, we decided it would be useful to provide an organized method through our own course structure for access to the Khan Academy psychology and science videos, even though we have our own video course. We like Khan Academy! The Khan Academy science videos can help you get your footing in any subject. In our opinion, they are most helpful in the areas of physics, general chemistry, and human physiology. Your mileage may vary, but we think they are not as strong in organic chemistry, biochemisry, and molecular biology. The Khan Academy approach is very different than our approach. Khan Academy videos are short and independent. Integrated MCAT Course videos are long and interconnected by a structured curriculum. They are different. Khan Academy videos are very good for what they are trying to do. They are useful. Having them accessible through our site makes our course better. They are here for extra help whenever you need them.
