Im a volunteer FF/Rescue Tech myself...Others may disagree but you need to work up your endurance...Push ups...pull ups, sit ups and running...that is all...
Also as big as the academy down there is, they should work out sesions run by them that you could go to...and from reading your test, there is nothing in there that you cant do, all very achievable...
Up here in Montgomery County, the has this...
Stair climb,
Hose drag,
Equipment carry,
Ladder raise and extension,
Forcible entry;
Search, Rescue drag and
Ceiling breach and pull.
