SAT Prep Plan site

[kyleiq]

I created a new SAT Test Prep website, www.satprepplan.com, and would like to get feedback on the site from an ESL perspective. The site is fully functional; the most interesting bit about it is the custom study plan creation tool. Students take the SAT practice test and then a custom prep plan is created for them based on their strengths, weaknesses, times to study, and time until the test. SAT Prep Plan also includes a bunch of practice problems, problem solving videos, SAT vocabulary, tips and other prep materials.
Please check it out and let me know what you think, I'm especially interested if there are any UI issues or bugs.
