TESU Computer Science (BA) Math Transfer

[kakasahib]

Hello Everyone, 
I am planning to complete the BA Computer Science Degree. I am NJ resident and live (will say 5 mins drive). 
I am more concern about the Discreet Math which i don't have in my current UMPI BLS Degree. Any suggestion that Study.com or cheaper other courses i can transfer?
I have completed UMPI BLS in IT and Project Management. 
I competed UMPI MAOL as well. 
The goal for me is to complete the Computer Science Degree. 
My all UMPI BLS Credits transferred from  Sophia which were around 121 where all the IT course (Intro ones)

Anyone has any suggestion? I can take Mercer county Discreet Math but its 4 month long and cost 192/Credit (almost $600) for 4 month. 

Thanks
