Is there a limit to Modern States?

Sorry if this it the wrong place to post this

I'm using Modern States to study/take advantage of their CLEP voucher program, and I'm wondering if there's a limit to the number of CLEP vouchers they'll provide free of charge. I'll probably use the site to study regardless, but if there's a limit I might choose some different paths to go about things.


Bonus Question: Is it worth getting a Sophia membership? Can I grind through courses in a day or two like I've been doing with Modern States?


Thanks for your help
