Review tiers 1–10

  • Checklists are parent-judged.
  • Written items: verify against practice set patterns.
  • Standard text: Topological spaces: definition and examples (Euclidean, discrete, cofinite) Open and closed sets; interior, closure, and boundary Bases and subbases; subspace topology Continuous functions and homeomorphisms Product and quotient topologies (introduction)

Practice test scoring

| Tier | Pass guidance | | --- | --- | | 1–3 | Most oral tasks smooth; majority of written correct | | 4–6 | 7/10+ total with clear understanding | | 7–8 | 9/12+ with explanations | | 9–10 | Near-perfect; ready to move on |
