Reviewing calculus concepts, particularly limits, continuity, sequences, and series, is beneficial before self-studying basic real analysis. While techniques for calculating integrals and derivatives are less critical for this purpose, a solid understanding of foundational calculus is essential. Multivariable calculus is not necessary for elementary real analysis. Engaging with theoretical calculus texts like Spivak's or Apostol's is recommended, as they serve as effective reviews while also introducing key real analysis concepts. Working through these books can provide a comprehensive understanding of both calculus and analysis.
