Quiz, report plugin suggestions please

On a site I am building I am needing a few plug ins, but am not sure what I need.

If anyone can help with suggestions I would be more than grateful.

Firstly, my site has client portals for every client that has registered.

I am thinking of using WP-Client for this (https://wp-client.com) If anyone knows of better please advise.

The portals will have certain functionality and features.
The following are features I am looking to have.

1. Quiz plug in:
I would like to be able to have client choose a quiz or test from a predefined and previously created list of tests, assign this quiz/test to an individual and create an individual link for the individual to use to login and complete the quiz/test.
The results will be emailed or piped back to the client and the individual taking the test.

I would also like the results to show up on the clients portal page if possible.

2. Receiving reports:
I assume this can be done with a simple form, but was wondering if there was a plug in that may handle it better and provide more functionality.
A “send report” link will be on the front page of website and visitors will click this and navigate to a page that has pre-defined form for receiving specialised comments.

These comments will be emailed to admin so I can send them to the relevant client, dependent on certain criteria.

I am hoping to find effective plugins for these but cannot find anything as yet. I am not a strong coder so am not confident of adapting plugins myself, but if I find what can be used I am sure I can find someone to adapt them for me.

Thanks in advance for any help I receive.
