Grade Boundaries
Edexcel International AS/A Level
October 2021
Understanding our Edexcel International AS and A level grade boundaries
This document shows the grade boundaries for our modular Edexcel International AS and A level
qualifications. For each set of grade boundaries, the maximum number of available marks is also shown.
For individual units, maximum marks and boundaries are shown for both the raw and uniform (UMS) mark
scales. Maximum marks and grade boundaries for the overall qualification (the ‘cash-in’) are only shown
in UMS marks.
International AS units and overall qualifications (cash-ins) are graded A to E. International A2 units are
graded A to E but we publish the theoretical A* boundary. Overall International A level qualifications
(cash-ins) are graded A* to E.
Where grade boundaries are greyed out for a particular unit, there are no grade boundaries available.
This may be because:
●
●
the unit was not available in this exam session
no-one took the unit in this exam session
Definition of terms
A grade boundary is the minimum mark at which a letter grade can be achieved. For example, if the
grade boundary for a B is 60 marks, then 60 is the minimum mark at which a B can be achieved. A mark
of 59 would therefore be a C grade.
For modular qualifications, assessments can be taken in various exam sessions throughout the duration
of the course.
For linear qualifications, all assessments must be taken in the same exam session.
A raw mark is the actual mark awarded by the teacher or examiner for an assessment. Raw mark scores
can be downloaded by Exams Officers from Edexcel Online.
Raw marks are converted to UMS marks for all modular qualifications. This is because raw mark grade
boundaries may change from exam session to exam session to take into account variations in the
difficulty of assessments. A Certifying Statement of Provisional Results (results slip) will always show the
UMS mark for modular qualifications.
