Set an activity as a prerequisite in the offering

Summary

Employee needs to complete the assessment to continue with the remaining activities in the offering

Hi All,

I have a requirement wherein course 'Occupational Heath Safety' has a self-paced offering with multiple activities - 

1.  Weblink
2.  Word Document 
3. Assessment
4. PDF

My requirement is that the learner needs to complete the assessment and only then proceed to the final activity of reading the PDF. This is similar to prerequisite concept but is only applicable at the course level.

Is there anyway that I can achieve this without splitting these activities into two courses or having it as a specialization.

Thanks,
