You don't necessarily need to learn maths, physics, biology however I suggest learning about grounding, centering, shielding, meditation, energy work and chakras. I also suggest those books by Scott Cunningham and Raymond Buckland. Hope this helps! :)
Hello, and welcome to the site. Basics is needed first so you learn how magick works. Meditation, grounding, centering, energy, atc. Also use the search bar. There is a lot of info on here. Check forums and articles. Also newbie central is good for you.
May you find what you seek. Blessed Be...
We all have different opinions, I'm still new to this, not entirely new (few months) but I don't see any reason why they should know all of it. If they went to school, they would be fine. I don't however see why these are needed for magick but I would like to know why :)
