IAL Grade Boundaries October 2025

Edexcel International A Level (IAL) raw-mark grade boundaries for the October 2025 exam series, for every unit in Mathematics, Physics, Chemistry, Biology, Economics, Business and Accounting. The Full UMS column is the raw mark that already gets the unit's maximum UMS, so you don't need full marks to get full UMS.
