Which paper should I take along with P3?

Dear Sir or Madam,

Hope you are well.

I am going to take P3 for the following session but I am not sure which paper should I take along with P3.

My situation:
1. Due to heavy workload, I can only spare 2 hours per day for revision.
2. I believe I will be better in discursive questions as I have passed P1 without any revision before.

I am considering to select one paper from P4,P5 and P7. Could you please advise on this? I am feared to take P4 as I got exemption form F9. (I passed F5, F8 and P1.)

Also, I have heard that P2 should be taken stand alone if I don’r have sufficient time. Do you believe it’s true?

Thanks in advance for your help.

Regards,

Jasper
