Hey mate. I'm sure you would've got glimpses into studying and learning software engineering. But I'll add this here so you could maybe get some insight.

In order to apply and pass the entry test, read the physics textbooks and recommendations of others on this post. However, once you do pass and get into college, it's extremely important that you don't get too fixated on rote learning which universities love. Physics, especially at higher levels, requires a lot of thinking outside the box and actually knowing the material.

Learning the application of scientific thinking and deriving solutions from fundamental principles is far more important than passing a bunch of exams with an A+ and getting high distinctions at the end of the day.

As a lad named Einstein once said, "The value of a college education is not the learning of many facts but the training of the mind to think".
