Query: A cheesy gimmick!

I borrowed these video tapes from a friend of mine who purchased them back when they first came out in the late 80's They should be called "Where there's a gimmick there's a sucker!"There's absolutley NOTHING in these videos that can "magically" help you get better grades! These videos help only slightly by showing you a few study procedures you probably already know (like I did) and currently use!! Bottom line, everybody has their own way of studying, but if you want to make better grades then:1. DO YOUR HOMEWORK!!!!2. Read and UNDERSTAND the textbook! Outline it if you have to. If you need to read it several times then DO SO!!3. Take good notes in class and study them in your spare time! A little less time goofing off and more time studying for a test could mean the difference between making an A instead of a B!!!There now, I told you what you need to do to make better grades and it didn't cost you a dime!
