Hello! 

I am working throught the Kahn MCAT course and am noticing that for my review I am requiring a lot of Khan material that is outside of the MCAT course content. For example: the MCAT seems to cover multiple types of aromatic heterocycles, where we would need to know both "aromatic heterocycles I" and "aromatic heterocycles II" content, yet only I is in the mcat course and II is in organic chemistry section of Khan. 

Would be super helpful to continue to add relevant material as many students expect this course to encompass all relevant khan academy material.
