calling for suggestions please --Moodle

<snip> I suggest you look, instead to Moodle. It is free and used 
widely. It's made for your application. https://moodle.org </snip>

As per my previous post, Moodle handles everything you request with ease.
I have passed the details to my daughter who has much expertise with 
Moodle and may wish to help you set up the site.
