Collating quiz results offline

Hello,

please i need ideas on a client request.

1. I have a published quiz project which contains 20 questions. After the 20th question, i do not want the learners to see the result slide but would like to know the results for the learners. How can I achieve this?
2. My client wants to be able to collate quiz result without an LMS, either when the timer has elapsed or the user actually clicks the submit button on completion of the quiz . The result will be saved as a PDF in a shared folder on a server. How is this possible?
