About

Your reference point for the ARE 5.0

Questions change every exam cycle; the concepts underneath don’t. Datum distills each ARE 5.0 topic to its fixed reference — one unit, one concept, and an original diagram wherever a drawing teaches faster than a paragraph — built to find and close the gaps in what you know before exam day. It complements official NCARB materials and the major video courses; it doesn’t replace them.

Why Datum

• High-yield, not a textbook. Every unit is the exam points plus the ones most often confused with them — distilled to what moves your score.
• The traps, in plain words. Pitfalls rewritten in our own words so the distinction finally sticks where it used to slip.
• Original diagrams. Where a drawing beats a paragraph, the unit carries one — drawn in code to a single visual grammar, never a stock image or a scan.
• Active recall, built in. Flip-card drills with recall-then-check and spaced repetition — retrieving beats re-reading.
• Learn once, tested everywhere. Most units are tagged for more than one division, so a concept you learn for one exam is already working for the next that tests it.
