Francesc was great for group theory! I'm really happy he's teaching the entire grad algebra sequence this year.

Professor Castella is really into linear algebra and it shows. His lectures are very clear and typically end early, and explanations never seemed lacking. Of our two midterms, one was very easy, while the second midterm and the final were more challenging. All tests, however, reflected practice material well. 10 webwork questions a week for HW.

The math department just verified that the prof never graded midterms, finals, or HWs and randomly assigned grades off of a single webwork assignment. Check UCSB Reddit for the entire email sent by math dept.

do NOT let this man teach anymore LOL, gave up on hwk like a month in and just.. never graded anything except the seatings (my final grade on canvas was about 1% lol), the tests were a mess (especially the first midterm), yeah wouldn't recommend him if you genuinely wanna learn about linear algebra because i know i didn't learn too much with him

He just released the final grades nearly two weeks after the deadline. He did not grade any tests, and I strongly believe that he just randomly assigned grades. I emailed him asking to see my test results, and also plan on emailing the math department if needed. Please avoid him at all costs, this is the worst class I've ever taken.

Thanks professor Morrison
