[Disclaimer: I'm absolutely not your target audience, and am not familiar with US testing] My immediate feedback would be that nothing on your website makes sense to me. I don't understand the concept of a cube. I don't understand why in your difficulty/concept/process diagram, Q2 of 6 appears to be the most difficult? I don't understand how your users are inventing knowledge. I also don't understand what I'd get if I signed up - you'd give me test questions that vary in difficulty, concept and process (whatever the latter 2 mean)? I don't know what cuves are, although I did find some cube shaped things on Google images. Okay, I clicked try for free and was surprised I got a working demo. My feedback feels harsh now, and the product seems great, so I guess the most actionable feedback would be to make it clearer you're offering an instant demo. I suspect if I knew what CUVES is (your target audience do?) it'd make more sense, so take that all with a pinch of salt - but I hope there's something useful in there. :) Also sorry I don't have the experience to answer your original question!
