First of all, there is no such thing as a dumb question when it comes to learning. It's great that you are seeking guidance and wanting to know what to expect in your university physics course. As for the difficulty of future subject matter, it really depends on your individual strengths and weaknesses, as well as your dedication and effort in studying and practicing the material. However, in general, university physics courses tend to become more challenging as you progress through the curriculum. The math will become more complex as you move into topics like forces, energy, and electricity. You will also encounter more abstract concepts and theories, such as Newton's Laws and the laws of thermodynamics. But don't let this intimidate you! With a strong foundation in conversions, kinematics, and vectors, you are already on the right track. Just make sure to stay on top of your studies and seek help from your professor or peers if you need it. Remember, physics is a subject that requires practice and patience, but the satisfaction of understanding and applying these fundamental principles is well worth the effort. Good luck with the rest of your course!
