Quiz that has stages to complete before moving onto next

I have used the Quiz coding as shown in the AppInventor2 book and would like to extend this so that a correct answer gives a score out of possible correct answers and when all the answers are given as correct there is another set of questions to answer.
Anyone interested in helping give advice please contact me.
