Every claim traceable to its source
Landmark papers and registry data sit alongside the teaching, each with a level of evidence and an independent verification link. Then rehearse the viva with Aster.

Ligamentization of the ACL graft
Free tendon grafts remodel through ligamentization but never fully replicate native architecture.

Live questioning
Aster asks escalating station prompts instead of static flashcards.
Marking & feedback
Every answer gets a viva-style mark, feedback, and what you missed for full marks.
Trusted questions
