I suggest you begin by using https://www.vetstream.com/login
This is a huge eLearning resourse for all species. You do not need to register individually for this site since you can use my email address and password.
You can either select which species you are interested in (on the upper right corner of the page), or enter a topic in the Search Vetlexicon box.
Here is a link to help you make the most of Vetlexicon - Vetlexicon User Guide
Note: This resource is exceptional since it is available to ALL vet students at AFU (not just those graduating in June 2020).
