Criteria Feedback
- You communicate a mathematically relevant comparison between deterministic and stochastic integration methods.
- You establish a clear general direction by linking convergence, stability, and local function behaviour.
- Your discussion shows some awareness of how the methods are supposed to work in theory.
- The research question shifts wording and scope, which weakens the sense of sustained focus.
- The topic is broad for the space available because it combines three different pathologies without equal depth.
- The method is not described with enough detail to show exactly how the numerical work was carried out.
- The comparison would be stronger if you defined one clear standard for judging the two methods.

Good
Criteria Feedback
- You use a good range of mathematical language accurately in many places, including terms related to integration, variance, and convergence.
- You demonstrate sound understanding of the Monte Carlo estimator and the basic theory behind numerical integration.
- Your treatment of the Dirichlet function and the improper integral of 1/sqrt(x) shows relevant mathematical knowledge.
- Some terminology is used imprecisely, especially when distinguishing ordinary Riemann integrability from improper integration.
- The explanation of variance and convergence sometimes blurs the difference between finite variance assumptions and almost-sure convergence.
- A few key claims need correction or tighter justification, particularly around the measure-zero argument and the classification of examples.
