Do the swims in the fins you dive in.

I would but I don't really have access to a pool prior to the test, so I just walk, run and bike to try to get in adequate shape.
Definately go with the lightweight split fins, to reduce fatigue!
+1 for fins without booties. Also, I thought it was against standards to wear anything other than a swim suit. Although, I could be wrong if you are doing it in open water.
I'd go for full foot fins, make sure you eat your bananas and stretch before you start. No booties means less bouyancy, that is, if the fins are negative. I also noticed that having your arms in front with a bit of angle upwards drove my feet down. If you can, try out some combinations before you do your test.
If memory serves, you are allowed to wear exposure protection but must be weighted to be neutrally buoyant.
To be honest, most people at or approaching the Pro level don't use full foot fins: they are "unitaskers" that don't allow you any flexibility in foot protection or strap configuration.
Perhaps you might consider typing this with "...most people I see at or approaching Pro level...." Certainly at the Pro level on Maui there are a significant number of full foot fins. My nearly zero to hero training at Ocean Divers in Key Largo included no shore diving and no cold water. Full foot probably would be fine for the vast majority of DM candidates, who are in warm water with beach shore entries (if any).
