I noticed the igcse final grades the one they show at the report card. lets say this is a subject like chem where the weighing is x1.25, x1.5 and x1. And the final marks is out of 200 so etc I get 58/80 x1.25 + 32/40 x1.5 and plus 33 for paper 6 which is 154 in total and out of 200 the percentage is 77% that is an B where above 80 is an A and so on. So how do the thresholds really apply to this like in the threshold it says to get an A for paper 4 eg you need 62 and so on. So my question really is how does the final grade relate to the threshold ik this sounds confusing so if u have any questions ask me
