The curriculum is taught in a flipped structure, which means you are expected to self-teach yourself the material before lecture (same for Roth-Johnson). During lecture, Deb briefly reviews the materials, but focuses mainly on clicker questions to reinforce the topics taught. The clicker questions count towards in-class participation and attendance.

The required materials are an iClicker (doesn't matter which model), and access to Biology: How Life Works on LaunchPad. This is ~$95 for 24 months access (I think 7B and 7C uses the same text). This is the online textbook to learn the materials and answer homework questions/practice quizzes/tests. Homework load isn't bad if you don't procrastinate.

Extra credit is earned by completing the Pre-Class Worksheet before each lecture and submit it online to CCLE. This helped a lot, considering it was worth an extra 10 pts each week.

Discussion is mandatory and the worksheets and activities completed during section counts toward overall grades.

There are two midterms and one final. The questions are mostly all True/False questions, which makes it very tricky. Make sure you not only understand the concepts, but make connections to other topics and know how to apply it. Pure memorization does not help a lot during the tests, since almost all of the questions are applications.

Deb is an extremely nice professor who is there to help her students during lecture and office hours. If you put in effort in pre-class assignments, this class should be easy!

This class (no matter which professor you take) is run as a "flipped classroom." This means that the majority of how well you learn the material is on you. During lecture, Deb spends most of her time asking us clicker questions, meaning it is pretty much expected of you to read the material and understand it by the time class starts. That being said, she still gives a brief lecture on the material you should've read previously.
There is extra credit, and the extra credit is SUPER easy. Although it doesn't add up to much (10 points total), it doesn't hurt to do it. The extra credit assignments go along with the textbook readings and are helpful to do and go over before midterms and finals.
To me, Deb's tests were tricky at first. There are a lot of true/false questions and her tests contain the type of questions that really apply the concepts you have read and learned about into different situations. What I mean by this is, this is not a class you'll do well in if you're just gonna memorize everything. You really need to UNDERSTAND the concepts well in order to do well on the tests.
But, you get used to the tests and the class isn't so bad! Deb is an extremely nice professor and is there to help her students. If you try and put in effort into your homework assignments and discussion section worksheets, you should be just fine.

As an international freshman student who had never learnt biology or related subjects before, I think it is easy to start learning life science with Deb. She is nice and interesting, and the homework are really helpful to your study. (But I guess all of the professors of 7A assign the same homeworks) Also,
she offers learning goals which help us to know what knowledge should we know after taking the classes. I have never fall asleep in her class. She may not be the best professor a UCLA, but she is definitely not the worst. Also, as long as you pay reasonable amount of effort to the course ( not huge amount), you will be fine, she is definitely not a professor who will effect your score or GPA negatively.
