My guess is that the code won't give any free exams.  That's just a guess.  That's why I paid the $200 for another month.  I am pretty much at the point of just taking exams.  But it did seem to move me through the weird pro-rated no exams subscription twilight zone.

I am thinking that it is because I did the guardian scholarship because it dose specifically say it is a college accelerator trial. If they wanted no tests they have other plans that include the coursework just no tests. Still an awesome deal for those who need it!
