Comments

Criterion A: Communication

A3—Too much detail in the tables detracts from conciseness and hinders easy reading. Appendices should have been used for some of this information.

Criterion B: Mathematical presentation

B3—This is appropriate throughout.

Criterion C: Personal engagement

C3—There is some evidence of this, for example, applying unfamiliar maths, creating his own example, but not the abundant evidence needed for level 4.

Criterion D: Reflection

D2—There is meaningful, but not critical, reflection.

SL Criterion E: Use of mathematics

E5—The mathematics used is beyond the syllabus, and good understanding is demonstrated.

HL Criterion E: Use of mathematics

E4—The work is sophisticated enough for a level 4.
