Your personal AI tutor for every subject, from notes to exam day.
Upload your notes, slides or past papers, set your exam date and target grade, and Astra assembles a topic-by-topic revision plan built around exactly what you'll be tested on.
Ask by typing, speaking or snapping a photo. The tutor explains concepts at your level, asks follow-up questions and keeps going until the idea actually clicks.
Generate guided lessons, flashcards, quizzes, true/false and smart-text exercises, plus an auto-generated podcast so every learning style is covered.
Practise with realistic oral and timed written mock exams that get graded, so you know where you stand before the real thing.
AI-coached CASPer practice questions and full mock tests
Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.
Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.
After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.
Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
