Even though I strongly dislike writing, this class was pretty enjoyable. We only had to write two essays, and the prof gave us helpful feedback and lots of time to complete them. There were also two easy group project presentations, and sometimes we had to write summaries of assigned homework readings.
Prior to taking the class, I didn't know much about the class's subject matter (various topics related to technology/ethics). I enjoyed learning about these topics in addition to improving my writing.
I don't think the fact that the class was all engineers made a big impact on the overall experience, but it was kind of nice to be around people with similar academic goals.

You will be writing essays on extremely interesting topics relevant to engineers and watching film snippets in classroom! Although there are summaries as homework, you are not expected to put much effort into them. The lectures are actually intriguing discussions on the current science topics rather than a commentary on the boring mechanics of English writing. You can even earn extra credit sometimes! I believe this is the best writing class for engineers in UCLA.
