The only thing I can think of would be to GTG on push ups, not suck on sit ups and run as much as the knee can take. Rest for maybe 2 or 3 days prior to the test with active recovery and hope for the best.
Don't expect to overhaul any bench mark numbers.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
