Exam Simulator
Write complete, fact-based mock exams against the clock, with autosave, a live Pace Tracker, and AI feedback on every answer.
For internationally trained lawyers
Timed NCA practice exams, with feedback on every answer.
Write a full mock exam against the clock. Then see what each answer did well, which issues it missed, and where your time went — before the real thing.
Your first full simulation, including AI feedback, is free. No card required.
How your answer gets marked
The feedback you'd wait 12 weeks for, in minutes.
Every question has its own marking guide: the issues in the facts, the rules and leading cases that answer them, and a model answer.
Issues you spotted, and missed
Q1 · 25 marks
- Covered: Operational conflict: can you comply with both?
- To revisit: Frustration of federal purpose (Marcotte, Moloney)
Sample feedback on a practice answer Each issue in the facts carries marks. See which ones your answer dealt with, and which it walked past.
Technique, criterion by criterion
Rule statement
Application
Sample feedback on a practice answer Scored from Beginning to Strong on the skills the question tests, such as structure, rule statement, application and use of authority.
What to fix before your next exam
Where to focus before your next exam
Add frustration of federal purpose as a second paramountcy branch.
Question 1 · Paramountcy
Sample feedback on a practice answer One fix per question, weakest first, then your answer side by side with the model answer.
- Marked only against each question's own guide
- Written to the current NCA syllabus
- Time and pace measured on every question
- Study guidance, not an NCA grade

Why Lexn exists
Built by internationally trained lawyers who have written the NCA exams.
We sat these exams ourselves. It is rarely the law that goes wrong. It is:
- running out of time on the last question,
- missing an issue buried in the facts,
- losing the rule you need in a stack of notes,
- and waiting 12 weeks to learn what went wrong.
Lexn is the preparation we wanted: full exams under the clock, feedback on every answer, and NCA notes organized for an open-book exam.
