Ok so I started this year as a pre-health major so I took the non-major physics classes (non calc based) and enjoyed them so much I want to take the calc based classes and start anew with physics next year. I did mechanics in semester 1, and E&M and optics and briefly touched on modern physics in semester 2. Next year I'll be doing mechanics first semester and then in second semester it seems like they ignore E&M and do just a lot about waves. Will it be easier because I've already taken the non calc course? Or is the non calc simplified so much that it will be quite difficult?
