Is it possible to update final aggregate marks in graduate details ??
If you have confirmed with pre-final and taken the test earlier then it is not possible to update from your profile.
Call or send an email to elitmus and ask them the procedure to update marks for those who have taken the test with pre- final marks and want to update final marks.
If you are going to take the test now, then take the final mark sheet and during verification ask the eLitmus staff to update it.
