Hi, i was exempted from taking F1 to F3, so I begin acca by taking F4, F5 and F9 and i managed to pass it all at the first attempt. The only difference from you is that I am a full time student, thus having more time to revise.
My advice would be to take 1 theory based paper ie. F4 and either F5 or F9 which is mainly on calculations. I would be inclined to believe a balance between theory and calculation paper will be a better option.
Perhaps you can look at the exam dates, and decide if you would have enough time to plan and study for all your papers before your exams 🙂
