I will provide you with a one of a kind website concept not used by any existing education training site.
Very intuitive methods to progress in any subject and to move to other relevant ones, so users can get more details on subjects they dont understand or move on to other subjects.
By approving the concept of my website, you can easily get fresh ideas of the domain name you can use for your project.
Because you asked for a website mockup, I will provide you with a simple web page with basic graphics that displays the concept of the site, you can change it later.
I assume that you will provide the data used in this site or helping users to provide it.
note that the important thing is the interactivity my site concept will provide to different users, whether they are well educated, well trained that want to learn more, or people that are learning for the first time.
