Homework comes in as a photograph.
Marked work goes back the same way.

Your student photographs the page in Telegram. It lands in your Homework tab as an ordinary submission. Nothing for them to install, no password, no scanner — and the rest of the practice runs here too.

Built and run by one maths tutor.

Predicted grade 18 / 20
An ambitious, largely correct exploration — Newton's Law derived from first principles, an original temperature-adjusted ODE model via integrating factor and cyclic integration by parts. For the full 6 in Criterion E: acknowledge the ambient-temperature drift and show the GDC setup behind the ideal drinking time t = 12.4 min.
✓ StrengthsOriginal ODE model beyond the HL syllabus · real kitchen-thermometer + room-temperature data · six Desmos graphs · 14-source bibliography.
→ ImprovementsFlag the k = −0.05 vs k = 0.0932 conflation · consistent rounding of b · sensitivity analysis on the phase shift.
