Changing answers in quiz without having to retake all questions

I have a question regarding quiz slides in captivate 7. I have a client who wants a module to assess how compliant they are within a particular field. This quiz will consist of up to 150 questions, each being either true or false or multiple choice.

I need them to be able to skip questions, if they are not yet ready to answer if they are compliant, I also need the quiz to be able to handle the fact that the client will need to change the answer of questions once they are then compliant.  However, I don’t particularly want them to have to re-sit the whole 150 questions again – is there a way of doing this?  Is the survey type of question the way to go?
