Go all out in the skills test, but not to failure. If you feel like you are good for a PB, go for it. If you are about to fail, I would bail out of the lift rather than fight it too hard.
The skills test is timed to give you a CNS hit and just enough time to supercompensate for a full hitout.
32 can seem long and drawn out but it depends on what precedes it. When I ran 37 once, 32 was definitely too long - I only did weeks 1, 2 and 4. When I ran two prep cycles consecutively, 32 was actually hard and I only began to feel stronger in the last week and a half when the deload started.
