Cantrill is a great professor. I would highly recommend him for 30A. After taking this class, I actually felt like I learned something. Going to lectures is a must because he does give hints to what's on the exams. AND definitely go to office hours... just be there for every office hour he has 'cause has extra office hours around finals for people who attend his office hours... and he gives out hints at his office hours. The exams were not extremely difficult but challenging. For my class, we had 3 quizzes, 2 midterms and a final. And yes, he does use the element "D" a lot but it's just to see if you have a firm grasp of the subject. I ended up getting an A- in the course and I did average on everything except I improved a lot on the final.
Great professor. One of the few professors in UCLA who takes his lectures seriously: no wry jokes, adequate material in each lecture, fluent, organized. He does bombard students with a lot of information per lecture, but all is clearly explained. Gives much extra credit to the class (though i never earn them) Exams are challenging though, but doable as long as you really really really really understand the material (btw an exam is supposed to distinguish able students from others rite). I got an A- and thinks the hard work required worthy...when you turn around after the intriguing final you'll find you've digested 70% of the textbook, and that's a great achievement... If you really want to learn Org Chem take him Those who take the class just for getting a good grade without much understanding better avoid him.
