Pearson Edexcel IAL AS Chemistry grade boundaries

Rows include current WCH11/WCH12/WCH13 papers and older WCH01/WCH02/WCH03 papers where they appear in the official Pearson International A Level PDFs. The newest available official series in the scraped Pearson page is January 2026. The table uses a short Variant column so the repeated unit titles do not crowd every row.

WCH11 / Unit 1: Structure, Bonding and Introduction to Organic Chemistry
WCH12 / Unit 2: Energetics, Group Chemistry, Halogenoalkanes and Alcohols
WCH13 / Unit 3: Practical Skills in Chemistry I
WCH01-03: older AS Chemistry unit codes in legacy PDFs
A / R suffix: alternate or regional paper variant where Pearson publishes a separate boundary
