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

Did a full timed practice test today and ran out of time with 14 questions left. Definitely have a time management problem.

The (Alabama Boaters) Alabama Boaters Certification exam has 136 questions and the time limit is 139 minutes by my understanding. That works out to roughly 70 seconds per question — which should be doable except I keep stopping on "Alabama Boaters 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 "Alabama Boaters" 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.
