Every page carries the running header 2025 TJC H2 Math (9758) JC2 MSM: DIFFERENTIAL EQUATIONS. The question document prints pages 68–76 (9 pages), opening with DIFFERENTIAL EQUATIONS. Question pages 8–9 (printed 75–76) contain the heading Answers and the short answer key, now expressed in each question’s Printed answer key section. The solution document prints pages 1–33. All attribution brackets and marks remain in native questions. The erroneous “6 (iii)” row label on solution p.4 is retained and explained in Q5.
