Why NCA prep feels so hard
Casebooks, syllabi and notes, and no clear sense of what the exam rewards.
Prep courses can cost more than the exams themselves.
No classmates, no study group, no one to compare notes with.
You find out what went wrong months later, when it costs another sitting.
One preparation system
Each part has one job: timed exams to train execution, NCA notes to master the law, and Study Circles for questions and support.
Write complete, fact-based mock exams against the clock, with autosave, a live Pace Tracker, and AI feedback on every answer.
Exam-focused NCA notes for available Library subjects, organized by the NCA syllabus: case snapshots, flowcharts, decision tables, and practice problems with model answers. Lifetime access to purchased guides, with updates.
Free NCA study groups for every subject. Ask questions, compare strategies, and share what worked with other internationally trained lawyers.
Free sample
Read all of Part I of our Constitutional Law guide free — case snapshots, decision tables, exam tips and a review with model answers, organized by the NCA syllabus.


How it works
Choose a subject and write a timed, fact-based exam, just like exam day.
Feedback on every answer: the issues you spotted and missed, how your structure held up, and where your time went.
Go back to the NCA notes for what you missed, ask your Study Circle, then write the next exam.

Why Lexn exists
We sat these exams ourselves, and we know how they go wrong. It is rarely the law. It is running out of time on the last question, missing an issue buried in the facts, or losing the rule you need in a stack of notes. Lexn is the preparation we wanted: full exams under the clock, feedback on every answer, and NCA notes organized for an open-book exam.
