I need a little help with real analysis.

I followed a course on set theory in my third year of studying mathematics. The formal logic language, though useful and very important for lying the foundation of mathematics is also hard to intuitively get, and I would recommend it as a place to start learning mathematics.

Instead I would start with calculus and some basic set theory, like the intro course rsadhvika recommended. Play around with some of the rigorous but more intuitive definitions there. If you want to understand real analysis topology might also be very worth your while after getting to grips with calculus.

Logic and axiomatic set theory, though a very interesting mathematical subject are not necessary to understand real analysis, so you can skip those altogether if you want. Personally I would revisit them after some time, though doing some propositional logic first might help with understanding the axiom systems.
