- How is the WKB approximation applied to physical situations? When is the approximation good? Discuss this in the context of the harmonic oscillator. (Murayama)
- What is quantization? (Aganagic) [Note: there followed an extended discussion.]
- Say some words about the Euclidean path integral over the circle, as applied to the harmonic oscillator. (Aganagic) [Note: I had no idea what this was about. It seems that the faculty sometimes end with a question totally not on the syllabus, as an early chance to say "you passed".]
