Hello!)) I am 19 and seeking help with self learning physics (and indirectly math) through to a theoretical level, and basically would like help in making a list of course material that I would need to go through to accomplish this. I do not want to go through a formal education route due to monetary concerns and would much rather just know this level of physics for the sake of knowing it and perhaps applying it to a few expirements. My current level of mathematical education is through Ordinary Diff Eq with light knowledge of PDE, I feel like it would be best to brush up on ODEs as I can be a bit hazy at times on it, I have taken a course in Statics, classical mechanics and electricity & magnetism (but similar to the math I can be a bit hazy). Finding a bit of material online can be somewhat convoluted and would not mind spending some money on text books. Any help would be significantly appreicated
