For the next two semesters, I will be taking about ~11 upper level physics courses. To be specific, within two semesters, I have to take optics, math based physics split into two semesters (covers differential equations, vector, integral, laplace, fourier, and complex analysis), thermodynamics, introductory course to modern physics, electromagnetism 1, mechanics, electric circuits, solid state electronics, and two labs. All the courses are 200 level classes, except for electromagnetism and a lab (which are 300 level courses). At this point, I'm going to go bald trying to build a fundamental understanding for all those courses and maintain a decent GPA. Any advice to save some hair would be most appreciated.
