Author note — to cover (Higher)

Higher on this course, as scaffolding for the braced G25 proof work: the vector to a midpoint or to a point dividing a segment in a given ratio, built as a fraction of the whole vector inside route expressions such as a plus two thirds of b minus a. (G25)

• Fluency — direct questions on fractions of a vector, limited to this lesson's stated scope (4 questions).
• Application — use the same skill in unfamiliar or contextual questions without introducing a later method (4 questions).
• Check — questions built around the exclusions and likely misconceptions named in the lesson brief (4 questions).
