MF stands for Multiplying Factor assigned on the basis of Random assignment Test(RAT) for each phase to the eCM assignments. Wherever RAT is not conducted, it is de facto taken as 1.

Weightage on an eCM assignment varies from 1 (CBSE Beginner) to 5 (JEE Advanced Scholar). Similarly Chap Test, Phase test etc are also assigned weightage that can be seen on details page. If Weightage is shown Null, it indicates that this particular Assignment / Test is not Considered for the calculation of CGPA.
