TESU calculus I help

[Max13]

Okay for my computer science degree at tesu I have officially finished the introduction to programming from study.com. The only require classes missing are sos 110, capstone, and calculus I. I plan on taking the calculus clep but the test centers are closed and when I ask them more than likely will stay closed until sometime in June which puts me in a tough spot as I plan on enrolling by the end of May and enrolling in my classes in June. I know I can send the credit anytime but I would like to finish it off now while my job is closed and I have the free time to knock out classes. I can not use study.com anymore as I have maxed out my tests for the month and do not want to pay $200 for another month. Sadly Sophia or onlinedegree.com do not offer calculus so that leaves I assume: Taylor, StraighterLine, and ASU. 

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?
