Spring 2016 - Pros: Actually learn a few useful things about statistics. You also learn a decent amount about some cool chemical engineering stuff. Cons: Easily one of the most difficult classes I've ever taken at UCLA in terms of detail, workload, and grading. He is fair, I'll give him that. But the sheer amount of work for this class is unbelievable - although the reports are only 5 pages, and the presentation a max of 10 slides, every single word choice must be absolutely flawless to get anything above a B. Tim Grasel is an insanely detail oriented grader who loves nothing more than to mark you off for formatting mistakes which you forgot somewhere in his 25pg Style Guide (just for this class), or maybe just because he was feeling like it and couldn't find anything reasonable to grade on. The facets of this class are numerous - lab notebooks, punctuality, oral presentations, homeworks, readings (hundreds of pages on statistics), design of experiments, designing your own final project (if it doesn't work you'll get a bad grade), quizzes, investigation reports, feedback forms, proposal, SO MUCH STUFF, and something is due every week.. Your grade is very dependent upon how much time you put into this project. For an A, you should be spending 20 hours/week doing stuff for just this class PER WEEK on OFF WEEKS and easily twice that on weeks where stuff is due. Lectures are absolute garbage. Don't go. Even after attending you will not be able to do the homework based on those alone. My rating of this class is like 2/10, and only that because you actually do learn some useful things. Grasel himself and the course organization gets a 0/10. This class is your worst nightmare; if you're terrified of this class after reading this, GOOD. YOU SHOULD BE.
