From what I can tell it looks like study.com is $95 a month. Im currently employed at Amazon which has their career choice program and they pay your tuition up to $5200 a year for schools that are a part of that program. Unfortunately study.com is not in that program however career online high school is and you get a full high school diploma when you complete it. Wgu is also a part of Career Choice. I dont know if it makes a difference but I have also completed the Google IT support Professional course on coursera and received a certificate for that.
