1. KnowFi: every question with reasoning
Wherever your practice questions are, in your university's learning portal, a PDF or a website: with one shortcut KnowFi shows the answer in the menu bar and, one click away, the reasoning from your notes, including multiple choice with several correct answers.
Good for: understanding practice questions from any source. Less good for: if you are looking for a ready-made question bank. More on Understand multiple choice.
2. Past papers from your department
Not an app, but often the best source: past papers show how your subject actually asks. Many student councils collect them.
Good for: getting to know your examiners' style. Less good for: explanations, since solutions are often missing.

As of November 2026. Details about other providers without guarantee; please check features and prices with each provider.
3. Subject-specific question banks
Some subjects have large question banks with explanations, in medicine for example AMBOSS for board exam practice.
Good for: standardised exams with a large question pool. Less good for: subjects where every university sets its own focus.
4. Anki: lock in the knowledge behind the questions
Flashcards with a review schedule, ideal for the facts that multiple-choice questions test.
Good for: retaining terms and details long term. Less good for: practising real questions. More in KnowFi vs. Anki.
5. Quizlet: study sets and practice tests
Flashcards and automatically generated practice tests, plus many study sets shared by other users.
Good for: quick, playful practice. Less good for: explanations that match your notes.
How to go about it
Answer questions from past papers or a question bank yourself first, then follow the reasoning with KnowFi, and turn wrongly answered questions into Anki cards. Why this works so well is explained in the guide to active recall.
