When I was studying for college, I was constantly on the search for a guide on how to study more effectively, and I found it for free at Gutenberg.
Type in "study" in their online search and find all the products you can on effective study habits.
Normally I would tell you to create a hard copy product out of this content, but what I was going to do is create a membership site out of all the content.
Students don't have hundreds of dollars to spend on information guides, but they do have $9.95 or $19.95 to learn how to get their studying done quicker, so they can have more fun.
And this is how you should market the membership site. Don't make it sound boring, make it sound like it will help them have more fun in college, spend less time studying while still getting better grades.
The membership site doesn't have to be anything fancy, you can buy membership scripts for under $100.
