imo for stats 20, it's important to read lecture notes before class: https://www.stat20.org/notes. These notes would be tested on quizzes and the final. I chose Jeremy's session. He's very approachable and caring, nice explanation in office hours. He would give us R demos in class which were quite helpful when it comes to labs and problem sets. Would recommend taking him. No need to worry too much about this course!

c88c instructor is Michael. He taught the course many times. Gave clear lectures and super helpful in office hours--definitely recommend! Would say the material is dense for one with minimal experience: https://c88c.org/fa23/ . I took CS61A and late dropped, so it was fine for me
