First check whether your specific TestGorilla format allows you to move back to earlier questions. Do not build a skipping strategy around an interface assumption.

When review is allowed, spending too long on one item can be costly because the assessment is time constrained. A deliberate skip can preserve time for questions you can answer confidently.

When review is not allowed, you need a different rule: set a time limit for yourself, make the best supported choice you can, and move on.

Use the current invitation and practice interface to confirm navigation. Your time strategy should follow the actual test mechanics, not generic aptitude-test advice. When you practice, test a few pacing rules and choose one that prevents a single difficult item from consuming a disproportionate share of the total time.
