Every course asset must earn its place in the study plan.
The course is being built in the same order a candidate needs it: establish a baseline, repair the governing concepts, practice finding the right electronic reference, and verify the improvement on materially different questions.
Begin with the baseline- 01Diagnose
Measure accuracy by domain and record confidence before seeing explanations.
- 02Rebuild
Use the 18-module map to target the exact decision that failed.
- 03Navigate
Practice the handbook and code path alongside the engineering method.
- 04Verify
Return to unseen mixed work after focused review rather than repeating memorized items.
Course build ledger
What exists now, and what comes next.
The public description will expand only when each content wave has passed technical, answer-uniqueness, units, reference, and editorial review.
Foundation available
40-question original baseline, 18-module map, six-week study sequence, and domain remediation.
Next content wave
Focused theory lessons, reference-navigation drills, and worked examples tied to the four exam domains.
Verification wave
Approximately 160 targeted questions plus mixed-system coordination scenarios.
Full rehearsal
One original 85-question mock with timing, section controls, analytics, and worked review.
Reference discipline
Current rules first. Supporting books second.
The governing hierarchy is the October 2026 specification, PE Architectural Engineering Reference Handbook v2.1, and the exact editions of the listed codes and standards. Textbooks support explanation; they do not override the supplied exam references.
ReasonSpan™ does not distribute the NCEES handbook or third-party standards. Questions, diagrams, and explanations are original and are written to teach the engineering decision rather than reproduce protected exam material.
Your next study block
Forty questions. Four domains. One prioritized plan.
Start the baseline now, pause safely, and return to the weakest domain with a concrete module recommendation.
