How to hide or show Chapters or Sections from TOC (Table of Contents)

Hi All,

Please help me to find this solutions ASAP.

1. I have 10 modules

2. There are 6 profiles

3. One of the profile should see / visit of all 10 modules

4. Other 5 have two common modules and 1 unique module

5. I have assessment (Random Questions Generated test) for each such profile

6. There is a 80% pass score.

7. I can choose any profile, view the course (mark complete in SCORM) and also take assessment relevant to that profile (and score 80%) to make my course progress as complete.

8. How can i hide Chapters or Sections from TOC (Table of Contents) to view only specific profile content.

Please suggest how can I do so by a single set of 10 modules and still achieve the 6 profile requirement. How do i launch assessment basis profile (as questions will be pertinent to modules in that profile).
