OK, I get what you're trying to achieve. But I went through your prototype and felt that I was being talked down to. Not sure if I'm just not your target market or whether this is a real problem.

You need to go find people in your target market who will give you a few minutes and sit behind them while they go through your prototype. Ideally you could monitor their outcomes and see if the education actually helped them, but simply seeing if they "get it" might be enough to get you started.

Distribution is going to be a challenge too. How do people find out about codecademy and Khan Academy? Will that same strategy work for you?

I'd note that Khan also has some finance related videos which are quite good.
