It acts as an interactive, patient examiner that quizzes them on various tech topics, evaluates their answers, and provides instant feedback without needing a human study partner.</p> <p>When I handed it over to my friend and ran a mock viva session, they loved how it gave instant marks and highlighted exact points where the answer was incomplete!</p> <h2> Demo </h2> <h3> 1.
