Really bad lecturer. He was just reading and copying his notes in lecture and not explaining anything. Confusion is the only thing I get in this class.

Professor Rosen is the classic example of what is wrong with professors at UCLA. He is careless, a very poor communicator, and extremely boring. The worst part about him is that his self-awareness is extremely poor, too (it does not seem like he is even slightly aware of how bad he is).

Yes, the class is easy and if you put in some effort, you will probably get an A. So if that is what you are looking for, go ahead and get the easy A if that is what you care about.

But if you really care about actually learning something useful, something that is not just a repeat of Math 33B, I highly encourage you to look elsewhere. If you are stuck with being forced to take this class, then I pity you. You will spend so many hours on this class not learning anything and still getting frustrated, despite receiving a likely A (the "projects" that he gives out in particular are real torture sometimes).

He offers the class a chance to resubmit homeworks and projects for full credit if they make corrections after receiving their work back. This might sound nice, but it just resulted in a large portion of the class just turning in really poor work initially only to copy the corrections that the TA's provide in order to get full credit and, as a result, not really learn anything.

The exams are fairly straightforward, but they test your ability to not make stupid mistakes more than actually demonstrating the concepts one learns in the class (the midterm had a couple of insanely long algebra problems that were almost impossible to get completely right unless if you are a robot, which I'm sad to say, some people who take this class with you will be).

Basically, to sum this class up, it sucks. Avoid it. Not worth it.

I took this as a tech breadth class and was only looking for an easy A. If you're looking for that, then this is the class for you. I thought Rosen was pretty funny too. But the material sucks haha. Projects and hw do sometimes take long, not all of them though. He tells you what is going to be on the midterm and final.
