All the negativity surrounding this makes it sound harder than it is.
Here is what I recommend:
Sitting 1 - Air law, ops procedures, Communications.
Air law and ops procedures used to be one exam with 40 questions, now it is two exams with 20 questions each. Just do them back to back. Throw in comms for good measure because it is really easy.
Sitting 2 - Aircraft General Knowledge, Principles of Flight
Related subjects, actually jolly interesting as a subject. Again, this used to be a single, 50 question exam, just do the two shorter ones back to back.
Sitting 3 - Navigation, Human Performance
Both rote learning rubbish, low point of all the exams...
Sitting 4 - Flight performance and planning, Met
Both benefit from being done in later stages of the training, when you have done the long nav briefing with your instructor, and had a fair bit of exposure to weather information in practice.
Now, if you don't feel up to it, you could split sitting 3 and 4 into two and max out your 6 sittings, but then you have nothing left if something goes wrong. Since a sitting can take 10 days, you could also do the two exams a week or so apart.
