The way ECE 112 works, you have two different instructor which each takes care of 5 weeks of the class. For this class 40% of your grade consist of 8 hw sets which are relevant to lectures, following by 30% midterm and another 30% for final. Also lectures are on week 1-4 and 6-9 and you get one week for each exam (weeks 5 and 10).
Dr. Castaneda teaches the first 5 weeks of class and he did an incredible job on it. Even though class is fully online, as long as you go over prerecorded lectures you will be fine. Midterm was similar to hw sets so you don't need to spend so much time studying outside class.

Prof. Castaneda is a god amongst men. His lectures aren't the most engaging but they're super straightforward. The homeworks are pretty manageable and you're never lost on them since they directly relate to the homeworks. Exams are super chill because sometimes, the Prof will straight up rip them from homework. He even gives some pretty helpful hints during the exams as well. Also, this class in entirely online, including exams so super flexible times. I definitely recommend if you need a class to fulfill elective credits or you're just interested in power like I am. All in all, the Prof is a super chill dude who is super nice on homeworks and exams.
