The Sharp method

Four steps, repeated until it sticks.

  1. Learn

    Short, focused explanations of the ideas that actually come up, one topic at a time.

  2. Recall

    Flashcards with spaced repetition. Cards you find hard come back sooner, easy ones wait longer.

  3. Test

    Quizzes and timed exams graded instantly, with a topic breakdown that shows your weak spots.

  4. Apply

    Real code you have to read and NGN clinical case studies, the way you'll be tested.

How it works →

Built for focused practice

Real code questions

"What does this print?" with syntax-highlighted C#, Java and Python, plus fill-in-the-blank and multiple choice.

Interview answers

Write your answer, compare it with a model answer, and tick off the key points you covered.

NGN case studies

Unfolding clinical cases with nurse's notes, vitals, labs and orders, followed by six linked questions.

Every NGN format

Matrix, drop-down cloze, highlight, drag-and-drop ordering, bowtie and select-all-that-apply.

Timed exams

Practice under a countdown, with results only when you submit.

Spaced repetition

Flashcards rated Again, Hard, Good or Easy come back at the right time.
