This class is the easiest upper div I've taken yet. Her midterm and final were decent. They had a couple challenging questions on them but as a whole were pretty doable. In class she makes it VERY clear what will be on the tests because she makes her questions very similar to hw problems and class examples.

Her lecturing is very tedious - this means its complete and exhaustive, but boring. She spends the first hour reviewing what we already know, so it probably would be doable to just read the reader, but you would miss out on what she emphasizes (which is what makes her tests so easy).

Like someone else said, shes a decent/easy professor so don't be scared off by the difficulty rating.

She might be good but she's not a generous grader as top 25% = B+.

Her lectures were pretty clear and definitely worth going to. Midterm and final were definitely manageable and didn't have killer curveballs that destroy the average. Midterm average was about 76 and final average was about 73. Overall quite decent as a professor and not worth avoiding because of her high difficulty rating.

What you would get out of Alwan's class is DSP! Really!
She's very effective as a teacher. Her tests are fair but could
get a little tricky. If you understand her lectures, you'll have
no problem figuring out those tricky questions.
Take 113 with her if you can.
