the best combination to take

Hi,

I get 50% off a 2nd course if I attend 2 classes.
I was wondering if anyone had done either P3,P4 or P7 together and could recommend the best combination to pick e.g P3 & P7 or P3 & P4 etc.

Keep in mind I plan on sitting one p paper in june and the other in september. so i can give myself more time to revise whichever paper i think i need more time on.

Also would the textbook and content i get for the june sitting still be relevant for the september sitting? only asking as they review each paper once a year.will the review be before or after the september sitting?
