I have no hard facts and figures, just some anecdotal evidence, but this reads like pure politics to me as well.

I have never struggled with mathematics, in fact I pursued it to college, then got infatuated with computer science - but my areas of focus (optimization and algorithm design) tend to overlap - and I find myself reading quite a lot of graduate level texts.

My girlfriend on the other hand has always struggled with mathematics, but wishes to pursue a career in computer science also. I watched her for several weeks struggling and worry about a college entrance exam, reading the obscurely written criteria and trying to read through the suggested resources.

It was only when someone else mentioned Khan Academy that we both went to look at it - I found the content accessible, very well presented (for the most part - a couple of the older videos could have done with an update!) and the accompanied exercises were excellent in reenforcing content - the added gamificaiton really adds to it as well.

My girlfriend passed her exam (> 90%) and was even told she should think about taking the extra level exam later on if she wished to skip a few pre courses.

To see her go from "I have no idea what to do" to "I know I can do this" was a joy - so thank you Khan Academy.
