This illustrative example uses synthetic work, but shows the same question, mark, feedback, and progress structure as a real analysis.
Q1(a) x² − x − 6 ≥ 0
(x - 3)(x + 2) ≥ 0
therefore x ≤ -2 or x ≥ 3
therefore x ≤ -2 or x ≥ 3

Why this earned full marks
The quadratic was factorised correctly and both valid intervals were stated.
Example lost-mark feedback
On a later trigonometry part, the method was correct but one solution outside the required interval was included. Check the domain before the final line.
