The Hardest and Easiest NCA Exams, Ranked (and What Order to Sit Them)
Ask ten NCA candidates which exam is the hardest and you will get a fair amount of agreement, and a few strong dissents. That is the honest starting point. Difficulty is subjective. A common-law lawyer who did a constitutional seminar in their first degree will find Constitutional Law less frightening than someone coming from a civil-law system who has never read the Oakes test. Someone who practised criminal defence for a decade will breeze through material that unnerves a corporate solicitor. So treat any ranking, including this one, as a map of where most people struggle, not a verdict on where you will.
One more thing before the list. The NCA does not publish per-subject pass rates. Anyone who tells you a subject has a "40% pass rate" is guessing or repeating a rumour. What follows is candidate consensus drawn from years of forum posts, study groups, and the experience of people who have sat these papers, not official data. Use it to plan, not to panic.
The ground rules that apply to every subject
All five core exams share a format, and it shapes how hard each one really is. They are open-book, but hard copy only, so your marked-up printouts and tabbed textbooks come in and your laptop does not. They run three hours. They are fact-based: you get a scenario, you spot the issues, you apply the law. And the pass mark is 50%. That last number matters more than people expect. You are not chasing a distinction. You are clearing half, which changes how you should triage a paper you are struggling with.
Open-book is also a trap. Candidates assume that because they can bring materials in, they can look things up on the day. You cannot, not at three hours' pace. The book is a safety net for the one rule you blank on, not a substitute for knowing the structure of the answer cold. Keep that in mind as you read the ranking, because it explains why the "manageable" subjects are still failed by unprepared people.
1. Foundations of Canadian Law — the hardest for most
Foundations tops most candidates' lists, and the reason is scope. Where the other subjects have a spine of doctrine you can drill, Foundations is broad and unpredictable. The readings are heavy and they range widely: the sources and structure of Canadian law, the institutions of government — Parliament, the executive, the courts — and statutory interpretation, alongside Indigenous legal traditions and legal theory that asks you to think rather than recite. You can prepare thoroughly and still meet a question you did not anticipate, because the syllabus is less a checklist than a territory.
What that means for your prep: do not try to memorise Foundations, and do not leave it for a light week. Read widely and early, build your own summary in your own words, and practise writing about themes rather than reciting cases. The candidates who pass comfortably are the ones who can hold a coherent argument about why Canadian law looks the way it does, not just what it says. Give it real runway.
2. Canadian Constitutional Law — dense doctrine, high stakes
Constitutional Law is the other subject that consistently lands near the top, and here the difficulty is depth rather than breadth. The doctrine is intricate and it interlocks. Division of powers requires you to characterise a law by its pith and substance and then assign it to a head of power, and the case law is layered. The Charter brings its own machinery: the analytical steps for a rights infringement, and then the Oakes test to decide whether that infringement is justified. Miss a step in the sequence and your answer loses marks even when your instinct is right.
The upside is that Constitutional rewards structure in a way Foundations does not. Because the doctrine is patterned, you can build frameworks: a division-of-powers template, a Charter-analysis template, an Oakes checklist. If you internalise those sequences and practise running facts through them, a scary subject becomes a methodical one. The people who fail Constitutional usually know the cases but cannot deploy them in order under time pressure. Practise the order.
3. Canadian Administrative Law — doctrine-heavy but patterned
Administrative Law sits in the middle for good reason. There is a lot of doctrine, and newcomers find the vocabulary alienating at first. But it is patterned, and two frameworks carry most of it. The dominant one is standard of review: once you can confidently work out whether a court reviews a decision for reasonableness or for correctness — the Vavilov framework — and apply it, a large share of any admin question falls into place. The other is procedural fairness: when a fair hearing is owed and what it requires. It is doctrine-heavy, but the doctrine repeats.
That repetition is your lever. Drill standard of review until it is automatic, and get the procedural-fairness framework — the right to be heard, an unbiased decision-maker — just as solid, because between them the two cover most of what a question can ask. Because Administrative and Constitutional share a public-law mindset and some overlapping reasoning, candidates who take them close together tend to find each one reinforces the other. Prepare admin as a small number of frameworks applied again and again, and it stops feeling like a wall of jargon.
4. Canadian Criminal Law — substantial but structured
Criminal Law is a large body of material — substantive offences on one side, criminal procedure and Charter litigation on the other — so nobody should treat it as light. But its substantive core is structured in a way that makes it learnable. Offences break down into elements. You work through the actus reus and the mens rea, consider available defences, and reach a conclusion. That skeleton holds across most offence questions, which means once you have the method, new fact patterns are variations on a form you already know rather than fresh puzzles.
Prepare it by building offence-and-defence templates and running practice scenarios through them until the analysis is reflexive. If you want to see how that issue-spotting works on a real fact pattern, our worked criminal law problem walks through one end to end. The procedure side — police powers, disclosure, trial within a reasonable time — is broader and less templated, so the volume is real; start early enough to cover the ground. But on the offences and defences, the structure is on your side.
5. Canadian Professional Responsibility — the most manageable
Professional Responsibility is the subject most candidates rate as the most approachable, and it is the most genuinely open-book-friendly of the five. The core material is codified. You are working from the Model Code of Professional Conduct and the relevant codes, which means the answers are largely in the text in front of you, organised by rule. When a question raises a conflict of interest or a confidentiality problem, you can find the governing rule and apply it.
That does not make it a free pass. People fail it by underpreparing on exactly that assumption, then discovering that finding the right rule and applying it well under time pressure still takes practice — and that quoting a rule without applying it to the facts earns nothing. But of the five, it is the one where a well-tabbed set of materials and a clear method give you the most reliable footing. Treat it as your most winnable paper, not your skippable one.
What order should you sit the NCA exams?
You do not have to sit these in any prescribed sequence, so use that freedom deliberately. There is money and morale riding on the order. Each exam costs roughly $500, and you get three attempts, so a smart sequence protects both your fees and your confidence.
A sensible default looks like this. Open with something winnable to get a pass on the board and learn how the NCA actually marks: Professional Responsibility or Criminal Law is a good first sit. Then take Constitutional and Administrative Law close together, because they share a public-law logic and standard-of-review and Charter reasoning cross-pollinate; doing them in the same window means you learn the mindset once and spend it twice.
The one thing to avoid is leaving Foundations until the very end and walking in blind. Its breadth means it needs the longest lead time, so start reading for it early even if you sit it later, and do not stack it against a hard deadline with no runway. Whatever you choose, front-load a confidence-builder, pair the two public-law papers, and give the sprawling subject the room it demands. If a first attempt does go against you, it is recoverable with a plan; we set one out in our guide to bouncing back from a failed NCA exam.
The thing that de-risks any subject
Here is what the ranking cannot tell you: how good your written answers actually are. You can know the Oakes test cold and still lose marks because you asserted a conclusion instead of applying the law to the facts, or buried the issue, or ran out of time on question three. The NCA marks the way you write, not the way you revise. It is worth understanding how NCA exams are actually marked before you sit a single paper, because the gap between knowing the law and scoring the law is where most failed attempts live.
The only way to close that gap is to write full answers under timed conditions and have them marked before exam day, while there is still time to fix what is wrong. That is what we built NCA Edge for. Our AI examiner, Lexi, marks your practice answers the way the NCA marks, and shows you exactly where marks are won and lost, issue by issue. We cannot promise you a pass, and nobody honest will. What we can do is make sure the first person to grade your work is not the examiner who decides your result.
Pick the subject you are most worried about, whether it is sprawling Foundations or dense Constitutional, write a real answer under the clock, and get it marked by Lexi at NCA Edge. Find out where you actually stand while you can still do something about it.
