Tips for studying for multiple divisions at the same time

During last Sunday’s workshop, there was a discussion about recommendations on simultaneous studying for multiple exams, in this case Practice Management and Project Management. Since there is some overlap, it might make sense to tackle them together.

Here is an approach:
Start studying for 1 month for both, then 1 month for dedicated division study. Then take that division. After passing, do one month of dedicated study for the next division before testing.

Another approach would be:
People who have studied for two exams in tandem have reported success with spending a bit more time prepping for the first exam, scheduling their second division soon thereafter (with a week or two delay).

I would be curious to see what others say to this. Please chime in.
