A score is the beginning of the review
A full-length result tells you how many questions you answered correctly. It does not by itself distinguish a concept gap from a reference-navigation problem, an incorrect governing model, a unit error, or a pacing decision. Capture those signals while they are still observable.
Run the attempt deliberately
- Use current authorized references and a quiet environment.
- Rehearse the eight hours of exam time and scheduled break within the broader appointment structure.
- Record confidence before seeing the answer so hindsight does not erase uncertainty.
- Flag questions for a defined reason, not as a substitute for making a first-pass decision.
- After submission, classify each error and assign a specific review or verification action.
ReasonSpan™ diagnostic boundaries
The 80-question ReasonSpan™ diagnostic uses original multiple-choice content. It models key timing, two-section, scheduled-break, and permanent section-submission conditions, but it is not an NCEES examination and does not claim to predict a result or reproduce every item type.
Choose a practice exam for the job you need it to do
The ReasonSpan™ Civil program includes an 80-question diagnostic, 44 targeted practice sets and a separate 80-question mock. The free five-question sampler lets you inspect the approach without an account. These resources serve different purposes; a high score on familiar questions is not a substitute for a fresh timed attempt.
| Resource | Best use | What to inspect before using it |
|---|---|---|
| Short free sampler | Inspect explanation quality and the learning interface before buying. | A few questions do not cover the full blueprint or establish readiness. |
| Broad diagnostic | Find weak domains and distinguish slow answers from uncertain or confidently wrong answers. | Coverage, reference paths, time records and a usable error report. |
| Focused practice set | Repair a defined weakness, such as selecting the controlling schedule path. | New conditions and explanations for every distractor, rather than repeated numbers. |
| Full-length mock | Rehearse pacing, topic switching and sustained execution after review. | Published question count, timer, break rules and independent questions. |
Original practice question: a delivery delay changes the controlling path
Use elapsed working days from Day 0. Two independent branches begin together: procurement and delivery take 9 days; site preparation takes 12 days. Installation takes 4 days and starts only when both branches finish. All links are finish-to-start, with no lags, resource limits or differing calendars. A supplier delay adds 5 days to procurement.
| Branch | Original duration | Duration after delay |
|---|---|---|
| Procurement and delivery | 9 days | 14 days |
| Site preparation | 12 days | 12 days |
| Installation after both branches | 4 days | 4 days |
What is the earliest achievable project completion time after the supplier delay?
Show answer and worked explanation
Answer B: 18 working days
Originally, installation starts on Day 12 and finishes on Day 16. Procurement can slip three days without changing that start.
The five-day delay moves delivery to Day 14. Installation must wait for the later predecessor, so completion moves to Day 18: a two-day project delay. Recalculate both branches whenever conditions change.
Why each option does or does not fit
- A. 16 working days
- This is the original completion time. It ignores the part of the delay that exceeds procurement float.
- B. 18 working days · Correct
- Procurement now finishes on Day 14, later than site preparation on Day 12. Four installation days give Day 18.
- C. 21 working days
- Adding all five delay days to the original 16-day finish ignores the three days of procurement float.
- D. 30 working days
- Adding both branch durations and installation treats parallel work as sequential.
Remember the decision: Earliest project completion is controlled by the longest required path. Available float can absorb part of an activity delay.
Turn the result into your next study session
Keep the initial response, time and confidence. After reviewing the method, attempt a different problem in a later session. Treat a correct answer after seeing the explanation as learning, and use new work to check whether you can apply the method independently.
| What happened | Likely issue to investigate | Independent check |
|---|---|---|
| Selected 21 days quickly and confidently | Assumed every activity delay becomes a project delay. | Calculate both branches in a new network before inspecting the answer. |
| Selected 18 days but searched for a long time | The model may be sound while reference navigation is slow. | Locate the scheduling terms separately, then solve another network. |
| Selected 16 days after remembering the original result | Did not update the governing condition. | Annotate changed inputs before recomputing a different example. |
