Methods of Proof in Mathematics

[Giantzebra]

Hello! I don't know if anyone will be able to help me, but hey - may as well give it a shot! At the very least, maybe someone here can direct me somewhere that may help me.

I need a last upper level math course for my ba. I would like it to be four credits, because that will save me from needing to take an extra class. 
Question 1: Does anyone know anywhere that I can get a four credit upper level math class?

Question 2: 
There is a website called westcott courses. They give credit through Brandman University and are accepted by TESU. They offer an Abstract Algebra course which is 300 level and for four credits. Listed as pre-requisites are linear algebra and Discrete math/Methods of Proof in Mathematics. I have taken discrete math and am planning on taking linear algebra, so I didn't think I would have a problem. However, I found out that they won't take my discrete math as a pre-req because it is more focused on computers. They suggested I take their Methods of Proof course first. The problem is that I don't want to pay for this course that I don't need. So, my question is - does anyone know of a free methods of proof or discrete math course that will cover the material in the syllabus that I'm pasting below?

Thank you so much!

I doubt you'll find a free course that gives you any credit, so I doubt they'd accept a non-credit course for meeting the prerequisite

if you live in new york state the SUNY system (State University of New York -- a group of public universities) has a bunch of upper level math courses that can be done online -- probably too expensive if you're out of state though
$1412 for 4 credits
$353 per credit for online out-of-state residents

they even have

I think they might accept a non-credit option. Their logic is that students were failing without the pre-req.
