Surro is a really nice professor who is always willing to help you. I took this class his first quarter teaching Econ 11 and it was fairly difficult but doable if you put in the time. The class was made up of a final and a midterm and he gives you practice sets that are recommended for these exams.

Surro is very sweet and understanding. All his assignments are reasonable and considerate. He also explains concepts clearly. Comparing with other Econ professors with horrible attitudes he is a true blessing.

The homework was optional. We got full points for submitting an attempt. They were occasionally long.
Lectures were prerecorded. During the lecture, multiple choice questions would pop up for us to try to answer, as a comprehension check. He went over them afterwards. Each lecture is followed by a short, optional, 5 question quiz that we got full credit for so long as we got 1 question right. Chris was pretty monotone, so I could see people feeling finding his lectures unengaging, though the multiple choice questions helped with that. If you don't like listening to the lecture, he also posted each lecture typed up as a LaTeX document.
Tests (one midterm and a final) were multiple choice (he switched to this format because of Covid. I believe he will switch back to FRQs once we're back in person). They were pretty conceptual. If one understood the lectures and homework, they probably did well.
He had a nice grading system. If you do a homework or quiz, you get points and the number of points you're graded out of in the end increases. If you don't do a homework or quiz, you aren't losing any points because your grade never included them to begin with. The effect is if you have to miss a quiz/homework, you're good. If you feel confident in your understanding of the material, no need to do any homework or quizzes - just ace the midterm and final. If you're insanely confident, you could even skip the midterm, since if you do better on the final than the midterm, your final grade replaces your midterm grade.
He held live sessions once a week on a service called Campuswire where he went over several example problems. He seemed more lively here than in the prerecorded lectures. People could post questions on Campuswire for everyone to see and (in my experience) he responded within minutes.
Having a strong background in math is very helpful here. We used several results from multivariable calculus (ex. Lagrangian multiplier method). I can see someone who's not so familiar with multivariable calculus struggling.

He was highly accessible through CampusWire (online discussion board system with a live video chat, office hours). If you have questions, you'll have them answered! Seek help early.

Before each exam, he'll share one past exam (mock exam). Class averages for each exam were in the C/B range; don't rely on a curve.

Surro basically went over slides that he created for each class. I felt that the examples he used on his notes were very easy in comparison to the problem sets and exams. The exams are super long for the set duration of time. I recommend to find a great TA. Definitely try to understand and how to do the problem sets. I would have done better in the course if I sacrificed the sufficient time necessary.

Unlike most people jere, I actually don’t find his lecture to be super engaging; however, the content is naturally on the dry side, so I can’t blame him. However, he is super helpful with the class, provides tons of material to study for and make extra office hours and review sessions for the final. He also makes fair tests, problems are pretty similar to his practice problem sets throughout the quarter. My advice would be to study his practice problems hard to prepare for the exams. Overall, I’d say I will take the class with Surro again.
