Yes, it may be if you’re not interested in the subject. Needless to say, anything seems complex at first but once you get to understand the basics, you’re in for a treat. In a botanical class, you'll be doing a lot of memorization, as you would in any other general biology course. If you are dealing with botany on a higher secondary level, then of course they'll go further into detail, and it would be a bit harder as it involves a vast subject that concerns relative study of plants in the world.
