Program updates and content corrections

October 18, 2026 · PE program skills expansion

• Expanded PE Mechanical: HVAC and Refrigeration targeted practice from 48 to 144 original applications, six per module, including numeric entry. Assessment edition 2026-10-18.2 archives prior questions and keys for saved work.
• Changed 16 Mock B governing tasks to reduce parallel calculation models with Mock A. Author timing budgets now fit the eight-hour working limit; measured candidate pacing and difficulty validation remain pending.
• Added Chart and Exam Skills Labs to Mechanical, Architectural and Civil. Mechanical and Architectural each include twelve psychrometric chart cases; Civil uses construction charts and tables. Every lab includes twelve alternative-response drills with account-backed first responses and later reflections.
• Added six guided visual teaching sequences across the programs, legible original charts, shared calculator and whiteboard controls, and four retention method cards. Internal technical and software checks do not replace independent credentialed PE review.

October 18, 2026 · PE Mechanical: HVAC and Refrigeration

• Reproduced and corrected a whiteboard drawing failure that could blank the study studio. Coordinates are now captured before React clears the pointer event; drawing also handles lost capture, extra pointers and empty paths safely. Saved diagnostic answers and section progress are retained.
• Applied NCEES-style most nearly wording to 241 applicable quantitative multiple-choice items while preserving explicit rounding, whole-person limits and catalog selections. Removed additional method cues, varied single- and multiple-response answer positions, removed four numerical precision cues and replaced six weak distractors with independently calculated engineering mistakes. Current assessment edition: 2026-10-18.1.
• Added edition preservation to targeted-practice records, including existing checked work and responses sent by a browser left open during a release. Started diagnostic and mock attempts retain their original questions and keys.
• Repeated cross-collection duplicate checks, grading and numerical-model checks. No duplicate IDs or number-normalized stems were found across the 344 core questions. Shared topics and governing models still recur across distinct problems; independent specialist review and empirical difficulty calibration remain pending.

October 15, 2026 · PE Mechanical: HVAC and Refrigeration

• Training now pauses in background tabs, other windows and program sections. A server presence lease prevents a closed or suspended browser from adding more than 30 seconds after its last report. Fifteen minutes without interaction pauses training until Resume. A timer-only reset clears inflated elapsed and question-pacing time while preserving answers, flags, notes and position. Timed diagnostics and mock exams retain continuous exam timing.
• Screened all 240 assessment prompts for standard-equation substitution cues. Revised 51 items: 16 applied calculation replacements, 32 multi-step prompts with reduced method coaching, and three presentation or distractor-data refinements. New attempts use edition 2026-10-15.1; started attempts preserve their original questions and keys. Topic alignment is checked against the published NCEES specification; difficulty equivalence remains uncalibrated.
• Added realistic cooling-tower, three-phase motor, open-tank pump and flash-receiver views paired with exact, legible vector schematics. Compatible older saved visual editions now receive these and the sensible-recovery 3D cutaway without changing answers or grading.

October 14, 2026 · PE Mechanical: HVAC and Refrigeration

• Revised nine quantitative questions after reviewing near-equivalent answer choices. The diagnostic LMTD item now requests 0.1°F precision and excludes the 55°F rounded-equivalent distractor. Both mock exchanger-sizing items and six mixing, boiler and wet-coil distractors now use distinct, independently recalculated mistakes. Existing attempts retain their choices under edition 2026-10-13.1; new starts use 2026-10-14.1.
• Upgraded all five figures in diagnostic Questions 1–40 with realistic equipment illustrations paired with precise vector schematics. Values, flow directions and unknowns are authored in vector artwork; no answers are revealed. Compatible saved attempts receive the visual presentation update without changing responses or grading.
• Confirmed that psia correctly denotes absolute pressure in the humidity-ratio problem. The stated inputs give water-vapor partial pressure 0.232595 psia, matching the printed 0.233 psia answer.
• Unified the PE Mechanical: HVAC and Refrigeration diagnostic and both mock exams around the PE Civil Construction assessment layout: compact timer header, full-width question panel, filtered navigator, on-demand tools and fixed navigation footer. Saved attempts, grading, question editions and clock rules are retained.
• Replaced typed-expression study fields with a movable Project Development and Documentation-style keypad calculator, including memory, history, keyboard controls and HVAC scientific functions. Timed mocks retain the physical-calculator practice requirement.
• Kept each numeric answer label and its formatted unit together above the answer field, correcting labels such as Answer (gpm) that previously split across separate grid rows.
• Corrected clock projection after account saves so a new server timestamp is never combined with elapsed time from the previous update. The server remains authoritative for timing and grading; navigation pauses and scheduled-break rules are unchanged.
• Made the diagnostic question navigator collapsible and moved it above the question. Diagnostic figures and tables use the full study-column width; all 40 current-section questions and review flags remain accessible. Timed mocks retain their exam-focused navigation.

October 13, 2026 · PE Mechanical: HVAC and Refrigeration

• Training diagnostics pause automatically when leaving the attempt for another study section and resume on return. Manual pauses remain paused; timed diagnostic and mock clocks continue. Responses and notes are saved before navigation.
• Reduced desktop sidebar spacing and widened the study workspace on large screens, with full-size mobile touch controls.
• Audited both mock forms against current diagnostic, targeted practice, sampler, lesson checks, transfer checks, Foundations Library and HVAC Decision Lab questions. No reused IDs or number-normalized stems were found; engineering topics and governing methods necessarily recur.
• Refined all 33 assessment SVG exhibits, redrew the counterflow exchanger, improved table styling and removed desktop exhibit clipping. Assessment visual edition 2026-10-13.1 retains all questions, inputs and keys; earlier attempts retain their original artwork.
• Removed repeating answer-letter sequences from all 24 lesson checks, the free sampler and single-answer transfer checks. Reordered choices retain their original engineering answers and per-choice explanations; positions remain balanced without a fixed cycle.
• Transfer edition 2026-10-13.1 keeps saved first responses, original choices, feedback and grades under their previous edition. Diagnostic and mock question editions are unchanged.
• Simplified shared lesson figure controls to one Enlarge schematic button, with Open in a new tab inside the enlarged viewer. Redrew the duct-route teaching schematic with larger labels, aligned branches and a clearer controlling-route result.

October 12, 2026 · PE Mechanical: HVAC and Refrigeration

• Completed an AI-assisted technical audit of all 24 theory modules, their specialist cases and the 344-question program. Independent credentialed PE review remains pending.
• Corrected the mixing extension's sea-level air states, the flash extension's receiver-property basis and a diagnostic dew-point item's saturation data. Updated assessment edition: 2026-10-12.1; started attempts retain their original edition.
• Strengthened a charge-comparison distractor and a delayed airflow distractor. New controls follow-ups test release into normal commands; previously started follow-ups retain their original problem.
• Corrected outdoor-air realism and suction-pressure wording in two transfer checks, with a revised mixing figure. Transfer edition 2026-10-12.1 preserves saved questions, figures and scores from the prior release.
• Labeled the cold-air workshop lookup as synthetic interpolation data rather than accurate ice properties. Expanded the control handbook route and published module-level review status. Paid HVAC enrollment remains closed.

October 11, 2026 · PE Architectural Engineering

• Replaced systematic numerical distractor patterns and re-authored Mock B scenarios around changed constraints and decisions; retained the 85-question form and domain counts.
• Varied multiple-response positions and added wood and masonry applications. Earlier mock attempts retain their original question revision.
• Separated self-reported lesson study from graded evidence. Domain summaries now display recorded response counts and insufficient-evidence states rather than a weighted readiness percentage.
• Renamed the public reference-selection task and replaced administrative pseudo-equations with decision checklists.

October 11, 2026 · ARE 5.0 Project Development and Documentation (PDD)

• Revised weak recall items into project applications and corrected item-level objective mappings while retaining each form's 35/35/15/10/5 section distribution.
• Corrected opening-record text overlap and the mismatched QB-027 transfer-structure companion exhibit.
• Added direct image-region selection to all seven mock hotspot items, with native keyboard buttons and the existing menu alternative.
• Supplemented fictional reference-search tables with original ADA 2010 and IBC 2021 learning applications. Source editions and exercise assumptions are explicit; these are separate from scored mock questions.

October 11, 2026 · PMP

• Strengthened written participation screening and added keyed application checkpoints for all 41 guided modules. Participation screening does not itself establish correctness.
• Instructional timers pause when you leave the page or switch away. Use one active learning session at a time so your instructional hours remain accurate.
• Revised weak alternatives in 12 mock questions under content revision 2026-10-11.1. Started attempts retain their original revision and answer explanations.
• Added a searchable formula and decision index and a complete public guided-module preview. A certificate still requires all modules, the final assessment and at least 35 recorded eligible instructional hours; planned minutes are not automatic credit.

October 11, 2026 · PE Civil Construction

• Added ten distinct SI instructional applications covering pressures, forces, flow, geometry and density.
• Corrected the auxiliary ME1-060 sling figure so its plotted geometry agrees with the stated 60° angle. The question's explicit load and keyed calculation are unchanged.
• Replaced repeated generic alternatives in all 132 learning-only guided drills with topic-specific mistakes and explanations. These remain learning exercises, not independent readiness measurements.
• Saved Civil practice retains its original alternatives. New practice uses the revised content without relabeling older recorded responses.

October 11, 2026 · previews and enrollment

Each program now has a complete original worked lesson with feedback available before payment. Enrollment buttons prominently show the existing seven-day refund boundary: protected answers and solutions must not have been accessed. Prices and access terms are unchanged.
