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.
