Do them. There are great courses offered by very good teachers. And it's free. Certification is based on pass/fail structure. If you get over x% (dependent on the course what x is), you get a certificate saying you completed the class. If you don't get the mark, well you don't get anything...
By sit in do you mean audit? If yes, then it doesn't matter if the session is full, go there first and grab a seat :P
As for your options anything Linear Algebra helps you in physics. I don't know the whole Calc I and II shebang; I thought Calc II was multivariable calculus? :S Well that's...
The deeper hue in the title is because it portrays the night sky! If you squint hard enough, you'll see little stars twinkling in the background :)
Quotes look awesome too!
Love it!

If your end goal is to understand the field of cosmology and 'higher level abstractions' as you put it, I'd say you ought to take the route of Classical Mechanics --> Thermodynamics --> Quantum Mechanics --> Relativity. Maybe do QFT after all that and graduate level particle physics. I don't...
I was on the same boat few years ago. I opted to do a double major in Theoretical Physics and Pure Mathematics. Since there were a lot of overlapping courses, (i.e. some math courses required to fulfill both degree requirements) I was able to pick up a few courses in other departments as well! I...
I'm with Marne on this one. Solution manuals just tend to make one lazy. Sure you can use the solution manual and follow how the proof was derived or the problem was solved. Then you proceed to generalize the methods and use them in the future to tackle other problems. But mathematics is a very...
Ohh yes. I always sit down with a highlighter, pencil and an eraser. The more I love a book, the messier it looks. My copy of Feynman Lectures of Physics gives an impression of a 2 year old's coloring book. =)

Hydrostatic Equilibrium for stellar processes; maybe some particle physics? Lagrangian mechanics?
Is this a generic astrophysics course for non-science majors or a core course required for a major? Undergrad or Grad?

To OP:
Although I'm not that good at physics yet(I'm a mathematician!), one thing that helped me tackle advanced mathematics and gauge my skills at particular area of interest (in your case this might be string theory, QFT etc) was to attempt to read articles from arxiv pertaining to my topic...
Whoa! That's quite the accomplishment. Congratulations! Which textbook are you using? How did you cover all the mathematical machinery and underlying physics required to tackle QFT in mere two years?!
