  7. Assessment: how is your knowledge and progress assessed?

Many of these questions are answered in the introductory table at the beginning of this article.

Anything else should be researched via your own criteria and the contact you make with course providers.

What Can I Expect Learning Biology Online?

There are a ton of resources you can use to learn biology online. Yet despite YouTube being packed with authoritative lectures, it can be lonely trying to study the topic without structure, deadlines, or the community of other students coming along for the journey.

Most courses will introduce you slowly to the topic, walking you through the basics before delving into more complex areas like genetics, evolution and the physiology of living things.

The video below is a good primer on what you can expect studying the subject online…
