Exercise 17: Computer-Assisted Instruction II

Date completed: 15/06/2018

More sophisticated computer-assisted instruction systems monitor the student’s performance over a period of time. The decision to begin a new topic is often based on the student’s success with previous topics. Modify the program in previous exercise to count the number of correct and incorrect responses typed by the student. After the student answers 10 questions, your program should calculate the percentage of correct responses. If the percentage is lower than 75 percent, display “Please ask your instructor for extra help”, and reset the quiz so another student can try it.
