Time management during NEW exam — how fast are you supposed to go?

Did a full timed practice test today and ran out of time with 15 questions left. Definitely have a time management problem.

The New Zealand Car Driving Test exam has 132 questions and the time limit is 105 minutes by my understanding. That works out to roughly 63 seconds per question — which should be doable except I keep stopping on "NEW exam" type questions.

My bad habit: I over-analyze questions I'm unsure about rather than making a best guess and moving on.

Any strategies that worked for you? Specifically:
- Do you go through once and skip hard questions to come back to?
- How many questions on "NEW" should I expect — is it worth the time investment?
- Is the real exam usually easier to pace than practice tests, or harder?

I'm good enough on the content, I think — it's purely pacing that's failing me.
