Dilemma path after F9

Hi, just wanted to see if anyone has some input on my coming exams. I just finished F9 now in September (fingers crossed I passed).

Now I am considering which exams to choose next, also with the changes coming next year in September when P1 and P3 merge into one bigger exam.

I’m sitting for 1 exam per quarter.

these are my considered paths.

Path 1.

December 2017 P1
March 2018 P3 (now they will be converted to the new format
June 2018 P2
September 2018 Optional exam P4
December 2018 Optional exam P7

This path will give me time to finish P1 and P3 before the change and if I would fail one on them on the first try I could still give it another try in June 2018.

If I take path 2, the order of the P exams does not matter so well.

December 2017 P4 (should be an advantage since I just did F9)
March 2018 P2
June 2018 P7
September 2018 New exam P1+P3

I would be happy for any input.

Thanks
Fredrik
