>>16696387 (OP)Your Physics classes won't actually get difficult until end of your 2nd year. Until then, you'll probably be doing something between University Physics and Griffiths in terms of difficulty. You'll be able to get A's in those classes without much effort as long as your IQ is above 110.
Each semester after your 3rd, Physics gets twice as difficult as the previous. For most students this is either or both of the following:
a.) Their math skills are lacking (most undergrad programs don't adequately prepare you for the math.) So to fix this, over the next 2 years (and really for the rest of your career), hunker down and get really good at math (algebra, geometry, calc, vector calc, linear algebra, PDEs, ODEs, and complex analysis). A good sign is being able to do every problem in the book
>>16696408 recommends. I actually used this book to learn much of my math a couple years ago after my prof recommended it.
By sophomore year know: Geometry, Calculus, Vector Calculus, Linear Algebra (as deep as math majors know it, just figure out what they're learning. The Linear Algebra class for engineers is typically shit), Complex analysis, ODEs + PDEs
b.) Their Physics fundamentals are lacking. Focus on the fundamentals.So many students fall behind because it's easier to plug and chug for you first year or two without giving much of a shit about understanding instead of focusing on the underlying foundations you need to build on later.
Take your time. Enjoy it. Study hard. Don't fall for the textbook memes these retards shill. Take baby steps, you have a year or two before it gets rough. If you focus on your foundations and math skills for the next couple of years, you'll be coasting with A's while your peers are being eaten alive by Sakurai. It's a marathon not a sprint.
Qualifications: Rising 4th year Physics major at T15 school w 3.943 GPA. Taken entire undergrad sequence and am onto graduate level classes. Boy do I love talking about myself on social media.
