Yes, examiners will expect you to plan a flight within an hour. So practice doing just that. The perfectly legal way to get a leg up is to get the weather and NOTAMS before leaving for the field, maybe even run through a few possible flights. Of course you get the Wx and NOTAMS again at the field, principally to catch any changes.
And yes, it's quite a feat to be away from flying for 3 months, then get yourself back to the level required for a flight test in a 7-9 day period while also dealing with work responsibilities.
The previous suggestion to book a couple weeks off is a good one.
