Ratings for Voiculescu, D
Based on 60 ratings for this instructor.
Comment: Avoid at all costs. The final turned out to be entirely differential equations despite him only covering it for less than 2 weeks. Also, his syllabus specified that we could skip the second midterm (20%) and add 10% weight to our final and 10% to our first midterm. Since I got an 100% on the first midterm, I skipped the second one because it was supposed to be a free 10%, but Voiculescu ended up just taking 10% off of my entire grade instead of adding it to the first midterm. Lectures are also completely useless as his handwriting is terrible and his accent is not understandable at all.

Comment: He is really quite good. Incredibly good natured and clever, and both show in the way he teaches. He has a clear train of logic which flows through lectures, and a nice way of presenting the material through as many proofs as he has time. Most importantly, for me, was that he is very understanding of how it is to not get the material. He is totally missing that slight arrogant asshole streak which many math professors have. This also means that he is good at explaining things from an approachable angle, and he was very understanding and helpful once that I went to office hours. All of this is, of course, provided you put a bit of effort into understanding his accent, but really, that's a detail. Assignments were ok, some were incredibly short and easy and others were very much the opposite, but nothing tragic. Exams varied (one easy, one quite difficult, one relatively ok) but in general if you went to lecture they were quite predictable.

Comment: All of my professors I rate for my first year at Cal is above 80, except this one. Someone please tells me why he is hired by Berkeley, and how does people understand him! He never cares his students, even never replying to emails! His exams are incredible abnormal. I admit the first exam is super easy, but from midterm 2, they really suck. Final is unbelievable the worst. There are NO previous final on the internet and he will not give them to you. You don't know what may be included in the exam and the only thing you will know is your bad and angry face when you are doing your final. Please, any future 54 students enroll another professor's lecture and let the department fire the guy.

Comment: Barely 1/4 of the class showed up to lecture after the third week. I myself stopped going a few weeks after because what he taught in class simply did not help during exams. The reviewer below says the grading scheme was irrational, but the rubric is pretty standard for your typical STEM class. Moreover, 15% of the grade was homework instead of the usual homework + quizzes. Based on the exams, I think he is on the easier side. His exams are short and reasonable, although the final was a different story. He is funny sometimes, and overall your standard math professor with an accent.

Comment: Pathetically the WORST instructor I have ever met during my first year at Cal! Despite his "old lad in the Up" look, he is pathetically terrible in every sense, from his bloody awful Romanian accent (sometimes I was wondering if a Romanian could understand him at all), to his intolerably cipher-like handwriting (not to mention the numerous horrible grammar errors within - or, is there a sense of grammar in his mind at all?). Also, he is extremely incapable of handling the modern technology - when he managed to keep the projector working well for the whole lecture, you would win the lottery for that day lol. His exams are just irrational - 20 total marks for a midterm and 40 for the final, with 1/3 of it True/False, and the rest of it annoying computations (even if you have got the correct answer, you can hardly have the confidence to go on to the next question without double check); the first midterm was naÃ¯vely easy (mean score: 17 out of 20), but the final went too far beyond what he had taught (if he taught us something at all). Furthermore he is hardly accessible. I sent him emails several times but he only replied my first one. Avoid him at all cost, or prepare yourself for self-study (or if you are lucky enough, have a fantastic GSI). (I got an A for this course anyway, but I do not think he has ever made a trivial contribution to this)

Comment: Everything you've read about Voiculescu is true. The bad lectures and the sloppy handwriting, true. I tried going to a few lectures, just to give him a chance but they were bad and didn't improve. The homework was pretty standard-- right out of the book. His tests were half computational and half true or false. The computational part often had messy numbers that made it easy to make simple mistakes and the true or false were very conceptual and largely came down to whether or not you could remember some theorem from the book. There was really no point in asking him questions during class. He can't hear and answers rudely sometimes. This class basically comes down to how good your GSI is and how good you are at teaching yourself.

Comment: Voiculescu's a friendly guy, but his both his accent and handwriting need time to be deciphered. Also, Voiculescu will do everything he can to avoid writing. He'll say things like, "I don't want to burden the blackboard," or "It's not worth the chalk to write this down." Things aren't any better in office hours. He will also never return your homework to you. The midterm was reasonable, and the final was take-home, so things weren't too bad.

Comment: He's really not that as bad as people say he is. His handwriting and accent do get unclear at times, but if you are paying attention and ask what is it he's writing, it's quite easy to get over it. Very insightful and smart professor, some of his proofs are thought provoking yet concise. Assignments are of reasonable length, and his exams properly reflect the difficulty of the homework.
