DocMarvin's four Degrees Accountability Thread

[docmarvin]

So I am signed up for the ENC-102 for March term. I went to the MBS Direct and when I search for the course, it says that there is "No Text Required For This Course".

***This is what I saw on the TESU website:

Do I have to purchase these books or not? I can't find a cheap one even for a used book. If it is not required, I won't buy it. Please assist. Thanks!
