I was thinking of starting p level with APM on the September section. I just wrote PM exam this June, but i am confident i’ll pass. I decided to go for APM because i won’t have to revise PM again.
You said there is a brought forward knowledge from SBL, so do you really think it’s a good idea? is SBL brought forward knowledge adjustable?
Starting APM as early as possible is a good idea given that the pass rates are not that high. However in my opinon it is better taking SBL first to adapt to complexities of P level paper. There are not that many things that need to be revised from PM after all.
For me there were several years between those exams and I did not revise PM.
