Grading correspondences are based on the Ecole Polytechnique implementation of ECTS at masters level. Grades A, B and C are clear passes, whilst Grades D and E can be accepted if compensated by sufficient higher grades elsewhere. Warwick marks map readily into this as follows.

ECTS grade used by Ecole Polytechnique, and being adopted by Swedish Universities	Warwick marks
A clear pass ++	70% and higher
B clear pass +	60-69%
C clear pass	50-59%
D compensatable	45-49%
E compensatable	40-44%
F fail	Below 40%
