Want to teach myself college botany?

<p>I like botany a lot and want to learn but I'm taking accounting. My school also doesn't offer botany but I don't want to transfer either. What's a good way to learn botany from the basics? What would basics even be? Cell formations? I'm wondering if Amazon sold Botany Introduction textbooks and they do, should I start there? </p>

<p>You should try an online course.</p>
