The course typically begins not with a review, but with an escalation. Students revisit probability measures, sigma-algebras, and the axiomatic foundations laid out by Kolmogorov. This is where many students realize the leap in difficulty; expectations and convergence (almost sure, in probability, in distribution) are treated with rigorous measure-theoretic tools.

Here is honest feedback from past students (anonymized from Reddit and internal course evaluations): The course typically begins not with a review,
The difficulty comes from two places:
Beware: STAT 201A is a course to “catch up” in real analysis. You need to already have the maturity. Many PhD students from engineering or computer science background retake real analysis (e.g., MATH 202A) concurrently—often successfully, but painfully.
