I recently got into graduate school for electrical engineering to study solid state electronics. I did my bachelors in Physics and will be graduating this May and start grad school in the Fall 2015. Here is my current cours schedule: Fall 2015 - Intro to Solid State Electronics (3 cred.) - Electromagnetic Waves and Radiation (3 cred.) - Semiconductor Devices I (3 cred.) - System Analysis (Linear Systems and Signals) (3 cred.) Is this too much? the first three are required courses for my concentration, solid state electronics. Thing is I have a strong understanding of EM waves and solid state due to a decent background on Optics and Quantum Mechanics, so will it be too ambitious to throw an extra course in there? Because usually for grad school even 3 courses can be difficult per semester.
