Here is a sentence worth reading twice: in the Ontario bar exam, you are not tested on what you know — you are tested on what you can find in about 75 seconds. With roughly 160 multiple-choice questions and around four and a half hours, the candidates who pass comfortably are not the ones who memorized the most. They are the ones whose index never lets them down.
What a good index actually looks like
- Subtopic depth. “Civil litigation” is not an entry; “setting down for trial” is. A good index maps the terms a question will use to the page where the answer lives.
- Current-year accuracy. It must be built on this licensing year’s materials. Last year’s page numbers are a trap.
- Exam-room legal. Binding and format must comply with the current Rules and Protocol — confirm in LSO Connects before you print.
- Tested under pressure. An index you have used for five timed practice exams is a tool. An index you bought the week before is a pamphlet.
The case for buying a commercial index
The established providers — Emond, LexPD, and Ontario Law Exam are the names that come up most in candidate communities — rebuild their indexes every year against the current materials, and each sitting thousands of candidates effectively stress-test them. If you are working full-time, articling, or simply value 30 to 50 hours of your life, a current commercial index is usually worth it. Buy early, and confirm the provider states explicitly which materials version the index targets.
The case for building your own
Building an index forces the deepest possible familiarity with the materials — you cannot index a chapter without understanding its structure. Candidates who build their own often report that by exam day they barely need the index for common topics. The costs are real: expect 30 to 50 hours of work, a version built on materials that may still receive last-minute LSO updates, and the risk that your first draft has gaps you will only find under timed conditions. If you build, start in week one and finish by week four.
The hybrid most happy candidates land on
Start with a current commercial index as the base, then customize it during every practice exam: add entries for the terms questions actually use, strike entries you never touch, mark the pages where you repeatedly get lost. After three practice exams, the index is half theirs, half yours — battle-tested and personally tuned. This hybrid gets you the commercial index’s completeness and the DIY index’s familiarity, for about ten extra hours instead of forty.
Drill it like a skill, because it is one
Whatever index you choose, train lookups explicitly: pick twenty random topics, time yourself finding each in the materials, and repeat until every lookup lands under a minute. Do this weekly. On exam day, the candidates flipping calmly to tabbed pages are not smarter — they are drilled.
