Paper F8 with P1 or P3

Hi,

I am hoping to sit the F8 paper in June along with either P1 or P3. Can anyone advise me which one out of the two will be better suited to be sat alongside F8. F8 is the only foundation paper I have left.

The plan is to get two of the 6 exams I have left out the way with this June, another two in December and then the final two in June 2016. I was initially thinking of sitting F8 and P2, then P1 and P3. However, I’ve been advised P2 is one of the more difficult papers and also requires has a lot of assumed knowledge from F7 which I am a little rusty on therefore I am hoping to use the time after the June sitting to sharpen up on my weak areas.

Therefore taking that into consideration as well, which combination of papers will it be easier for me to pursue?

Thank you in advance.
