First of all Bill, if what you've posted is true, that you're 74 years young, following the routine you've outlined, and on track to pass that test -- then you're just straight badass in my opinion. That's seriously awesome.
My only thought is that, if I was in your place I'd probably do a trial run of the test and use that to figure out what I need to work on. Some of that stuff may be really easy for you, other parts may be more challenging. Run a mock test and see where your weaknesses are, then focus on making them your strengths.
I'd probably drop most exercises that didn't help me improve my weaknesses. For example, let's say you can already easily do the 50 push-ups in one minute, then why bother with all the chest/tri training (DB bench, pushups, tri extensions)? For that matter, why are you doing tri extensions at all? If you do compound chest stuff (pushups, dips, whatever) hard enough then that should engage your triceps plenty.
Anyway, let the forum know which areas of the test you're confident in and which parts you're worried about. That's really the key info that anyone is going to need to give you truly useful advice.
