How to manage time for tests
Answer the easy questions first.
A sound time-management strategy during tests is to answer the easy questions first. The idea is that you will quickly work through these questions, probably quicker than you had budgeted for, allowing you extra time to work on the more difficult sections.
The issue with this strategy, versus working through every section as budgeted, is that you might skip a question thinking that it's more difficult than it is. You also run the risk of not returning to questions that you've skipped.
