Mr. Chavaria is one of the best professors I have ever had; A real old school, down to earth type. If you grew up on the block or just want to know what that life is about. . . you will love his style. His subject material is always interesting & he knows his stuff. He doesn't BS, so don't try to BS him. His lecture material is good stuff & the reading is fascinating. His tests are all from the material he covers in class and his test are open book. but you need to do the reading or you will be lost at test time. He loves to have students ask questions & partcipate in class discussions. Super instructor, CCSF needs more like him. Oh, don't get caught texting, talking. or sleeping during his lecture or one of his film presentations. The results can be very funny if its not you !
