If you read my blog and never take away anything but this, I will be happy that my efforts have not gone to waste:
Use the MIT Open Courses.‚ http://ocw.mit.edu/OcwWeb/web/courses/courses/index.htm
MIT (one of the most prestigious universities in the world) has made their entire course selection available to read and work through online.‚ I personally am using it to refresh and grow my business knowledge, using their Sloan School of Management courses.
If I was someone who was 15 years old again, I would eat this up.‚ Most of your classes in high school are BS, but these courses are genuinely amazingly useful.‚ I recommend you guys look into any of the courses that interest you and take them on your own time, as quickly or slowly as you wish.‚ Though the faster, the better :).
