The three websites I would most like to use on the mid term are...
1) http://www.shmoop.com/economics/ because it does not focus on one topic but covers almost everything we learned throughout the class. Not only does it hit many key aspects we talked about but it does it in an organized manner.
2) http://www.amosweb.com/cgi-bin/awb_nav.pl?s=gls because it has a quick search. That makes it easier to find vocabulary with we learned a lot of throughout the class.
Again this is a very organized study tool. I like how everything is in alphabetical order because it's extremely easy to follow.
