Wikipedia  Very Informative  but not at all 100% correct ... Do not take the cited as absolute truths. They may seem right. Remember however a person who has signed up for an account can ruin a good article  by editing it. If you do know what has been written as being a 100% true comment  and other remarks as not so. It may be a users way to rewrite history in the article you are reading ... believing the fskse info may cause course failure. While that major couse depended on your final grade. The better your final mark when applying to graduate school is very real!
