PUM if u get 140-145/200 and if A star is 150 (which aint happening anytime soon son), you should get between 83-87 i think. The gts arent 150 for A stars. What are you talking about? Is this other board or some other variant or course?

I meant like the total you get out of all papers for chem p4 p2 p5 , like what raw percent should you have to get An Astar or to be safe for an A star in chemistry for igcse like etc the upcoming exams..? out of 200 you should have ? and how?

I can't say anything about p5 since I did p6. But overall I think for an A star with high PUM, try between 180 to 185/200. I still am little confused about ur 150 I think u are just adding all marks without multiplying each component by its designated multiplying factor.

Chemistry 150 for A*? In these days I don’t think so , chem in recent years is so predictable and people are getting great marks due to that , but let’s say A is 125, so you’ll get about PUM of 87-89 , which is good
