10.1 One-Hour Written Exam Pacing
Key Takeaways
- The ACI Field Testing Grade I written exam is closed book, one hour, and contains 55 multiple-choice questions.
- A 55-question exam in 60 minutes gives about 65 seconds per question before review time is reserved.
- Pacing should protect easy points first, then return to calculations and wording traps.
- Because each method or practice has its own minimum score, candidates must avoid abandoning any category.
Use the First Pass to Collect the Points You Already Own
The written exam is closed book, one hour, and 55 multiple-choice questions. That format leaves about 65 seconds per question if the time is divided evenly. In practice, candidates should not spend the same time on every item. Some questions are direct definitions, method-scope facts, or simple sequence checks. Others require calculations, correction factors, or careful reading of an invalid-test scenario.
A strong first pass collects the reliable points. Read the stem, identify the method or practice, answer direct questions, and mark anything that requires extended math or uncertain wording. Do not let one density calculation consume the time needed for five easier questions. The written exam does not give credit for effort spent on a single problem if the clock prevents you from seeing the rest of the test.
| Exam fact | Strategy effect | Candidate action |
|---|---|---|
| 55 questions | Every question matters | Avoid leaving blanks |
| One hour | Time is tight | Use rounds, not one slow pass |
| Closed book | Recall must be built before test day | Memorize high-yield values and method logic |
| Multiple choice | Elimination is useful | Remove impossible units, signs, or method mismatches |
| Category minimums | Weak methods can fail the exam | Track practice by method, not only total score |
A useful time plan has three rounds. In round one, answer direct questions and mark longer ones. In round two, work calculations and method scenarios that need more focus. In round three, review marked questions, check answer-sheet completeness, and inspect numerical entries for unit mistakes. If the testing format allows review, use it deliberately instead of rereading every question from the start.
The exam questions are spread across the required ASTM methods and practices, with between five and ten questions on each. That means the exam is not safe for a candidate who knows slump very well but ignores density, air, sampling, or specimen practice. One category can be small enough that a few missed questions create a category failure. Pacing must therefore protect coverage across the whole test.
Closed-book preparation should make common facts automatic. You should not need to reason from scratch that the exam has 55 questions, lasts one hour, uses multiple choice, or requires both per-category and overall passing. You should also be able to recognize which standard is about sampling, temperature, slump, density, pressure air, volumetric air, and making and curing specimens.
Use this test-time routine:
- Write down no unauthorized notes unless the testing rules provide an allowed scratch area.
- Move through the first pass quickly and answer direct recall items.
- Mark calculations, long scenarios, and questions with two plausible answers.
- Return to marked questions with method identity and units in mind.
- Use elimination when an answer belongs to a different ASTM method.
- Check that every question has an answer before the one-hour limit ends.
- After practice tests, score by method category as well as by total score.
The best pacing plan is boring and repeatable. It prevents panic, protects easy points, and keeps one difficult method from stealing the whole exam. Practice it before test day with 55-question mixed sets so the one-hour format feels familiar.
