I have several Quizzess, each with randomly selected questions from a huge question bank.
I need to account also the number of each repetitions of each Quiz, and evaluate the total grade as
Sum (i=1,nQuizzes) ( Sum(Quizz(i)-score(j), j=1,nQuiz(i)-repetitions) )
The more repetitions of each Quiz each student does, the higher score he will get.
Any help with such grading scheme, please ?
