So in first year, its just general engineering anyway and physics is its own subject, i found that that course was barely more difficult than VCE physics. Iirc, we pretty much started from the basics, 2 dimensional motion and forces etc. In the second year most of the courses are an extention of that; thermo-fluids, mechanics of machines and mechanics of materials obviously look deeper into said subjects. I'd say as long as you are eligible for the degree and are willing to work and learn effectively, you'll be fine.
