Edexcel International A Level (IAL) raw-mark grade boundaries for the January 2021 exam series, for every unit in Mathematics, Further Mathematics, Physics, Chemistry, Biology, Economics, Business, Accounting and Psychology. 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.
