Where marks go in AA SL Unit 2
From the IB subject reports we summarise on AA SL Examiner Insights, in our own words:
- Answer in the wrong form: asymptotes not as equations, coordinates vs values, unfinished answers. Lines are equations: write y = … or x = …. Give exactly what the question names (a value, a point, an interval). Finish the arithmetic: integers as integers, fractions with integer numerators and denominators in lowest terms.
- Transformations and inverses: incomplete descriptions and f⁻¹ notation. Name each transformation with its type and value ("vertical stretch, scale factor 3"; "translation by the vector (2, 0)"), in a valid order. Rewrite logs with the laws first. f⁻¹(a) means solve f(x) = a.
The questions here are original, written in the style of IB papers with IB-style mark schemes; for real papers see the IB Maths AA SL past papers page.
