TESU calculus I help

[dfrecore]

I like the cost of saylor $25 exam but I have a lot of negative things about their exams. 
Straighterline seems good but the cost of the course seems to be the most expensive: $170 for the class minus the typical $50 coupon is still $120 and only one month to finish the class
ASU is new but overall I kinda like what they are offering. $99 self-pace calculus class where it comes from a 4-year institution and is free upfront. So from my understanding, i can enroll in the class and study as much as I want, and technically if the test centers open up just take the calculus clep instead. Then if they do not open up in time, I can still convert the class to credit for only $99 which is still cheaper than StraighterLine. Any thoughts? Also, is the asu calculus for engineers the right class to transfer if needed for tesu calculus I?

I would do ASU.  Not sure which one, maybe do both and pay for the Calc for Engineers only if you do both, or Brief Calc if you can only complete that one.  My guess is that TESU will give you calc credit for it, but nobody has reported here what TESU brings them in as.
