I'm a bit confused after looking at the grade boundaries document, I'm planning to do P1,P3,M1 and S1 which leads to the full A Level. What percent do you need to get overall across 4 papers to get and A*,A,B and so on...? Some help would be greatly appreciated!
It varies. Thresholds are set for each exam period that reflect the variation in difficulty that occurs from one to another and whether the staged or composite examination route was taken. For the same reasons, they also vary depending on the exact combination of regional variant exams taken and whether the staged or composite examination route was taken https://help.cambridgeinternational.org/hc/en-gb/articles/115005937829-How-are-grade-thresholds-calculated-
