Professor Joshi is hard.

He teaches directly from the textbook which is good! Homeworks are assigned from the textbook but not graded. He gives out two quizzes, each worth 10%. 1 MT and 1 Final.
quiz1 10%
quiz2 10%
MidT 30%
Final 50%

His quizzes were simple - 1st one covering math32B material because we need to know it. 2nd one covering capacitance. Easy questions.
His MT was mainly smith charts. Just be careful! A lot of people aren't and if you do the problems in the book and the assigned homeworks, the MT should be a breeze for you!
His final was mostly proofs of equations, and some smith charts. Really tough stuff especially if your foundation for math32B is weak. Luckily for me i spent a lot of time proving the equations to myself when i studied so it wasn't much of a problem. He doesn't ask anything too difficult though.

Oh yeah, one caveat - you don't get any cheat sheet for anything. That means you have to memorize MANY equations. It's a headache and this class will most probably be time consuming but it's worth it when you get into 101B because it really builds your foundation for electromagnetics!
