Best Courses for PCB design?

Currently my summer break is going on after completing 4 semesters. I am thinking of learning PCB design so that I can invest this time in some productive things and also EARN SOME MONEY VIA FREELANCING. Also I am thinking of choosing IC design and semiconductors as my major in the upcoming years. So you guys pls tell whether PCB design is a good and beneficial thing to do ( if not then which thing aligns best with my dream field which is IC design) and where I can find best resources to learn it.
