example score

9/16

Thermodynamics Knowledge (TK)

Measures how well you understand and can apply core thermodynamics laws, properties, and process relationships across conceptual and calculation-based questions.

Foundations to reinforce

Developing command

Strong command

0 – 6: Foundations to reinforce | 7 – 12: Developing command | 13 – 16: Strong command

A score of 9 falls in the Developing command range, indicating solid understanding of many principles with some remaining gaps in applying them across scenarios and calculations.
