| 2026-11-02 | Secure → Secure | 2 Nov, non-calc: P = 6r^3 typed p/6 = r3, v(p/6) = r: first line right, root unclear, lower-case p. After one prompt, on paper: cube root(P/6) = r, root over the whole fraction, capital P. Wording said 'write r = on your last line'; subject still on the right. Value right, required form not met. | session 138 |
| 2026-10-22 | Secure → Secure | 22 Oct, cold, non-calc, back to back: M = 4t^3 -> M/4 = t^3, t = cube root(M/4), root over the whole fraction, 2/2 lines; A = 9r^2 -> A/9 = r^2, then square root(A)/3 simplified unprompted, 'r =' missing from the final line. 2/2 unaided, no bridge needed (19 Oct needed 3x3x3). | session 130 |
| 2026-10-20 | Secure → Secure | homework #11 Q5 set 21 Oct, due 25 Oct: y=2x^3 and y=5x^2 back to back, cube root vs square root covering the whole fraction. | standalone |
| 2026-10-20 | Secure → Secure | 19 Oct: V=2r^3 needed a 3x3x3=27 bridge to reach the cube root (first attempt used a square root); A=5r^2 then done unaided; root not bracketed over the fraction. | session 119 |
| 2026-10-07 | Secure → Secure | Exam practice 7 Oct (test #7, attempt #15, timed) Q6, the stretch item: make t the subject where t appears twice, in a fraction: 'skip', 0 min on focus. Set, not answered; 0/3. Marking only: no status change. Retrieval outcome: incorrect (not attempted). | standalone |
| 2026-09-07 | Secure → Secure | 4 Sep starter: V = kr³ made r the subject, cube root taken correctly. Three weeks after the 19 Aug exit check where she divided by r twice. Loose end closed. | session 6 |
| 2026-09-03 | Secure → Secure | 2 Sep starter: made x the subject of 5x + 2y = 20, writing the subtraction step before dividing. Linear rearrangement only, so the cube-root loose end is untouched. | session 2 |
