<p>A basic understanding of quantum mechanics books probably requires linear algebra. </p>
<p>You don’t need physical intuition for math or CS, but it kind of depends what you want to do. Mathematics obviously interacts with physics (you’ve seen this happen), and indeed, it is not unheard of for physical intuition to lead to a breakthrough in mathematics, when one might expect the relation happens the other way around! Now this is the most glamorous sort of result of having multiple kinds of intuition…</p>
<p>My suggestion is made from a more humble perspective, in the sense that I think you’ll feel very good about how you spent your time if you develop intuition in physics too, and you may find it possible to have it interact with the other kinds. You are at an early enough stage of education, presumably, to actually pull this off without the pressure from finishing college requirements and graduating. Early college and late high school is a great time to start exposing yourself to different things, I think.</p>
<p>Who knows, you may find you prefer physics - after all, you’ve hardly seen any math, physics, or CS, very likely, as compared to what you’ll see in your years of college, and the most important thing is developing the confidence and desire to try things out in the future. Obviously you don’t have to do any of this, but you might find it makes you happy :)</p>
