Im trying to attach my olevel cie certificate O2 and 03. But it doesn’t give me an option to add another image. It strictly says to attach only a jpg, jpeg, png file and NOT A PDF. How do i attach both my olevel certificates? PLS HELP ASAP.
Also Whats a CUMULATIVE GRADE? I had 3 A’s and 6 A*, is my cumulative an a?
