What math and physics do I need to learn before studying quantum mechanics?

edit: I found what I was looking for. But Idk how delete the post

TL;DR: How much math and physics do I need to learn before I can understand quantum mechanics mathematically, especially equations like the Schrödinger equation?

What level of physics and mathematics do I need to reach before I can start understanding the mathematical side of quantum mechanics? For example, how deeply do I need to study calculus, classical physics, modern physics, etc? I can understand the concepts behind the equations and what they mean, but I'm not sure how much mathematical and physical knowledge I need to understand more complex equations in quantum mechanics.
I hope my question is clear. English isn't my first language.

You will need functional analysis and everything that comes before.

Great news, is if you are okay with handwaving some of the math details, then knowledge of Vector Calculus, Linear Algebra, and some complex analysis can allow you to work through a book like Griffiths.

With just calculus, you learn what they call modern physics in the states (i call it intro to some topics of QM light)

Thanks for the response. This really helped me figure out what I should study next. Luckily, I have access to Griffiths, so I will give it a try.
