Quiztime

I have long been interested in quizzes of all types and having read and enjoyed the Harry Potter books I decided that they would provide an ideal basis for a multichoice quiz.
After much experimentation,debugging and rewriting, Quizp is the result.

The player is given the choice of deciding which book to have him/herself tested on and then is asked a series of multichoice questions.
The quizmaster is a Microsoft Agent character who reads the questions aloud. This makes the program very suitable for children who may be poor readers.
Those who are visually impaired can also take the quiz as they can listen to the questions and have them repeated as often as they wish.
The quiz can be completed fully using the keyboard to answer rather than the mouse.

The questions are asked in groups of ten and if the player succeeds in answering them correctly he moves on to the next level.
If he gives an incorrect answer he is given the opportunity to restart the particular level he is on.
If the player makes too many mistakes then he/she must restart from the very beginning.
Scores are recorded and a contestant who completes the quiz successfully is given the opportunity to print a certificate of completion.

The aim is to have fun and then to go back and read the books again!
I would welcome any comments and suggestions about the program.
