I took his class last year, and I very much enjoyed it. Because the classroom is flipped (lectures at home and problems in class), it took a little bit of time to get used to. However, as an aspiring teacher myself, I am always happy to see teachers/professors trying new things -- especially when they are as passionate as Carlos is!

Professor's teaching style focuses on practice problems and online resources. Lectures are pre-recorded, but the in-class time for solving problems is helpful. Unstuck ai and the free textbook were great study tools alongside the practice tests.

Lectures are recordings with notes (both handwritten and more polished typed-up notes) available online, while class times are used to go through practice problems. I prefer this format to standard in-class lectures (though ymmv), and the in-class practice problems helped me develop my intuition for real analysis. Tests are take-home over 24 hours.

As others have indicated, lectures are flipped, with class time used for problem reviews/clarifications. I often struggle to keep up with real-time lectures, so this approach made the class much more accessible for me. 118 series is very difficult, but prof was caring and very approachable, emphasizing proof writing skills over regurgitation.

Avoid. Boring lectures and unorganized

Very bad teacher, hard to understand, would never take a class of his again.
