Does auditing a class and taking it later for credit look bad on my transcript? I am currently a freshman and I'm thinking of taking 3 upper division math courses next semester: Linear Algebra, Abstract Algebra 2, and Topology. However, I think that 3 math courses for credit would overwhelm me. I still would like to learn all 3 of them. 

I was considering auditing Topology instead. I do plan to take the course again in my sophomore or Junior year for credit. Will this hurt my graduation school admissions?
I thought auditing was just sitting in on a class that you aren't taking?  It's not on your transcript.  So how the heck can anyone tell, that you audited before taking something?  

Source: I audited classes and took classes for credit.  Audits not on my records.  Go check yours to be sure.

P.s.  I personally don't see the point.  If you are going to take a course (audit or paid), you should do best effort in it and take it once, unless you fail. If you know you're not doing it right, than don't audit.  If you do it right, than no need to take it for credit--you mastered it, previously when auditing.  So move on to the next battle.
