Grateful to have had Ethan for LING120C, and learned a lot in his class.

Lectures are structured in a "follow along" way with handouts for almost every class. Although some parts of lecture are reading/copying from this worksheet, the fill-in-the-blank/complete derivation sections are super helpful and are great resources for completing homework and studying.
There are weekly homework assignments based on the previous weeks lecture material, and Ethan/TAs are very helpful in clearing up any ambiguities and offering small hints. Homework is worth 60% of your grade but can be easy points with your lecture worksheets for reference and optional homework partner.
The exams are open note (see how the worksheets can be helpful) and open book; I found the exams to be extremely fair with one or two challenge portions to test if you can apply the material. The midterm and final exam are each worth 20% of your grade.

Overall, I would definitely recommend taking a course with Ethan due to the fact that he puts in the time to structure the material in a clear and digestible fashion.
