It's a little dull looking. The site could use a little eye appeal, graphics, imagery, content, etc. I don't understand the purpose of the calender. I think you could "sell" yourself more on the main page, what your site is about. A little more dept that you help with math solutions, etc.
Will your idea work? Is your target college/high school? Can these customers pay and how? I can't answer these questions, but as long as you have solutions, that's fine.
One thing that got me was the I don't have all day statement. If I needed your help/services and was willing to pay I would want a little more attention/dedication than the statement makes.
I think mostly like personal daily or something like that. When I made this site, I just wanted to put some of my daily basics on it and didn't think of how my audiences feel about it.
Anyway, I still ned to think of how the site gonna be.
