- Then go back to your bookmarks and work them out.

Study Tips
On technical questions, don't get bogged down in unfamiliar terminology. If you don't recognize a term, you're unlikely to figure it out on the spot—acknowledge it quickly and move on. Use the surrounding context, answer choices, and familiar terms to guide your reasoning, but don't linger on any single difficult question.
Practicing against a ticking clock is the best way to beat exam-clock anxiety. Use these timed tests to build your pacing, so you learn to move steadily and never burn too long on a single question. By test day, the format feels routine.
If you're stuck on a problem, don't waste time—move on. Before you do, however, quickly eliminate any obviously wrong answer choices. Even ruling out one or two options significantly improves your odds of guessing correctly. Eliminate what you can, make your best guess, then move on.
You're given plenty of time, so use as much of it as you need. Don't get rattled when other people finish early — finishing first isn't a prize. Work at your own steady pace and review your answers before you submit.

IFGC 305.4 requires appliances in public garages, repair garages and similar areas to be installed not less than 8 feet above the floor; however, where motor vehicles can pass under the appliance, it must be installed at the manufacturer's required clearances and not less than 1 foot higher than the tallest vehicle garage door opening — 12 ft + 1 ft = 13 feet. The 6-foot figure applies to private garages (305.5).
