I am returning to school, and I want to take a course in real analysis and abstract algebra this fall. I have been out of school for a year due to health reasons. The only math class I have credit for is Calc III, which I took first semester of my freshman year. I was enrolled in linear algebra and diff eq., but I had to withdraw from school early in the spring semester so I never got credit for them. I plan on taking a proficiency test to place out of diff eq., which I already know, and the introductory math proof writing course. I'm probably going to take the Linear Algebra again, because I feel I need a thorough review of it. My school doesn't list any prerequisites for the Analysis or abstract algebra sequence. You can only get into it by filling out a form at the mathematics department and receiving approval from the professor of the course.
