Low cost ACE reviewed history courses from Shmoop.com

Then it would seem worth taking the 'risk' at failing the Unit 1 Test (as they can be taken twice) for the two courses I don't get to properly start before the 26th, to ensure I'm locked in (enrolled) at the current rate for the History credit courses. I don't see what I would have to loose, in my case I only need one 3 credit US History course for my degree requirement - the other two are just a good option for low cost liberal arts course credits. Does this seem reasonable to you?

That's exactly what I've done for the other two courses, I'm using them as general education electives.
I'm going through the quizzes as quickly as possible to get a hang of what's there. Here's the info I copied on their site on grading:

Grading Policy
In order to pass the course, you will need to receive a 70% or higher final grade. Your final grade will include the following:

Unit Tests. You'll see these at the end of each unit, except for the final unit.
Navigate to the unit tests via the Syllabus feature to the left of the content area.
Final. You'll see this at the end of the course.
Navigate to the final via the Syllabus feature to the left of the content area; it will be the last item in the final unit.
Each question is valued at 3 points each. Thus, unit tests are worth 60 points each, and the final is worth 150 points. The grade breakdown is as follows:

Each unit test = 8% of your grade (total of 80% of your grade for all unit tests combined)
Final = 20% of your grade

Please note: quizzes, which appear as activities, are optional and will not be counted as part of your grade. They are intended as comprehension checks to be sure you feel comfortable with the material at a base level.
