My fellow Bruins, if you are logged on to this teacher's ratings, you are probably actually considering taking his class. For your sake and mine, please exit your browser now, go to the registrar, and find an alternative class. His tests are impossible. His TA's are just cruel and you cannot understand a word that he (or his TA's, for that matter) is saying. I managed to survive a quarter with him. YOU might not be so lucky. My TA was picky and then some when it came to grading lab reports (he actually gave me a point off out of fifteen for writing an intro that was "too long"). DO NOT TAKE PANG!
I felt that lecture was a waste of time except for the ones directly before an exam. If you don't want to go- ask a friend to pick up the hand outs he prints up every lecture-- you need them for the labs-- His english DOES get in the way of learning - he prints up his own requirements for each lab- separate from that in the lab notebook and sometimes the grammar or syntax will be so wrong it is difficult to know what he is asking for. The class is a waste of time-- it's mostly to demonstrate that you can follow directions and calculate error-- the only main concept learned that isn't covered in chem 20 A or B is Beer's law. Tests are challenging mixing calculation with hypothetical experiments and definition. The detergent quuestion this year i felt was completely off topic in terms of what was done IN LAB- all we did was test how much STTP was in ONE TYPE of detergent-- we never compared the two types and never learned aobut the significance of STTP exceptt that it creates acid rain-- so there is no way i would know why there was more or less of it in laundry detergent than in dishwasher detergent.
Dr. Pang is probably the easiest teacher I had here at UCLA. The pre-labs take about 15 minutes and the postlabs 20 minutes. Then in order to study for the test do the sheet that he gives you and then review all the concepts and think of possible questions that he may ask. Try to type them and make up your test. If you happen not to do very well on a test even though he says he doesn't curve you can end up with an A even if you get C's on BOTH midterms. but try to do better Which are between 70%-79%.Just learn how to be fast and don't procrastinate. Do the postlab right after lab and do the prelab after you do the postlab.If you have lab on Tuesday and Thursday do the postlab whne you get home. Then do the prelab right after so you will only have to work on Tuesday and Thursday and on Monday and Wednesday menorize the procedure easy A for anyone who will be taking 30L.
Although Pang was organized during lecture, he did have an annoying tendency to refer to topics covered in future lectures quite often which could be distracting. His lecture guides were quite helpful for the labs and for studying for exams. However, the review sheets he gives out are quite misleading. I did those thoroughly yet did not do very well on his exams as his questions were worded horribly at times and the questions bore no resemblance to those on his review sheets. Labs aren't difficult, but reports can be tedious.
Overall, Pang isn't too bad, but I really disliked his exams. He also doesn't curve, so you really need to do well in the labs if you want a decent grade and aren't having much luck with his exams.
As a person who is supposed to convey new material to his students, Pang is not that bad. He knows his stuff, and he knows how to make students understand it. However, he is the most hate-inspiring person I've met in a while. On the final, he gives this question that, if you precisely follow his instructions, is impossible to answer. He uses the phrase "DO NOT USE MOLECULAR WEIGHT!" twice in the same problem, but without the use of molecular weight the problem is unsolvable. Of course, he menat a different thing, but why the heck should students worry about that during the final? OK, some professors do not master English or cannot express what they mean clearly in this language. But in this case, they should acknowledge their mistakes. Pang did not do that. Actually, as far as I've heard from other people who had taken his classes before, my case is not unique. This guy just thinks he is always right period. Unfortunately, he is unavoidable, as someone pointed out, so if you have to take his class, know that your grade in his class is largely a matter of luck. If HE makes a mistake, YOU are screwed!!
I got an A on the midterm, and A's on the labs, but somehow i got a B+ in the class- while someone I know got a fail on the midterm got a B in the class...and I looked back on my final score and he closed his grade book all fast saying that he already made the grading distribution....blah!!!
Look i had pang for 20L and i got an A. It was not impossible. It wasn't even all that hard. His tests were fair. I liked Pang. He taught a clear strait forward class. Maybe its different for his other classes but he seemed like a perfectly legitamite level teacher to me.
