Merge two cptx files with assessment

Hi All,

Here is my client requirement below:

There are two units suppose unit 1 and unit 2. Both units have assessment at the end. So when I am copying all the slides of unit 2 into unit 1, the result page is same for both the assessment.

But my client want:-

Unit 2 should come only when learner complete the unit 1 means when learner passes the 80% of the quiz in unit 1. But this should not report the LMS completed as unit 2 is still remaining. But that is possible from my side.

The problem I am facing is:-

When the unit 2 assessment will come it shows the incorrect result data as it shows both the quiz results. Please I need your help in this area.

Regards,
