Fastest platform for three courses

[warriorlawyer]

Hi guys,

I work full time and it is really hard to study in a library for CLEP exams. I have tried but it killed my desire to get these credits done .

I need credits for calculus, statistics and microeconomics. Which platform would be the fastest and widely accepted? 

I want to use to those credits in order to get admitted into Finance/Economics masters. I am currently missing those courses from my undergrad as I finished law school.

Any help and recommendation is appreciated!
