High school computer science project (Used graphics library of C++ 3.0). I had to code this with Turbo C++ as CBSE (the examining body) made it mandatory to use that as the IDE.
Most OOPs concepts like polymorphism, inheritance and encapsulation were utilised. Data file handling too was used. I devised an interesting algorithm to award points via the quiz function - points are awarded based on swiftness in answering: quicker the user response, more points will be awarded provided that the user response is correct.

5 billion years from now, the sun will become a red giant (will not happen in my lifetime and yet this phenomena scares the hell out of me).
