Comment: I took 3A with Marsden in Spring 2014, which was practically a whole year without ochem. I went into 3B pretty nervous but it turned out to be alright. Sarpong's exams were pretty fair, averages were generally quite low but not ridiculously low. His pace in lecture was just fine and gave us students enough time to copy every single word on the board. Sapling homework wasn't that helpful and just a pain in the butt. He gave us enough practice problems and textbook recommended problems to study for the midterms and final, but partial credit is hard to come by with the mechanisms.

Comment: I took Chem 3A with Pedersen in Fall 2014, and I have to say that Sarpong made me hella like Organic Chemistry. Sarpong speaks at the perfect pace during lectures (unlike Pedersen where I was just scribbling done notes without understanding the content), and is extremely helpful during Office Hours. Chem 3B was no doubt a challenge, but I really enjoyed learning about the practical applications of the mechanisms we were learning, like ergosterol and vitamin D production. Sarpong's tests are a bit tricky, but curved very generously. Overall, Sarpong is a BRO. Disclaimer: I got an A+ but had to work for it.

Comment: I was so excited to take Chem 3B because I loved 3A so much with Pedersen. I actually hated this class. Sarpong goes really slow in lecture, which is really nice and he writes on the chalkboard, but I honestly did not know what to do for this class. I got a B in Chem 3A and i received a C in the 3B half. I really wish I was able to take it with Pedersen or Marsden because I did not learn anything in Sarpong's class. His tests were terrible for because the majority of his exams were mechanisms and I would always get 0/30 or 0/75 on mechs and so I would bomb the midterms and final. What's really nice about Sarpong is that it is really hard to fail the class. If you're looking just to pass a class with no effort, take it with Sarpong, but if you want to study hard, learn a lot and get a good grade, I suggest Marsden or Pedersen. With sarong a 25% was passing which is very generous and the most lenient curve I have ever seen.

Comment: This class made my semester feel like hell. His tests are extremely difficult (averages are around 45-50%), and he does not give you that many study resources. On top of that, he rushes through lectures, making it difficult to grasp the difficult material. Do not take classes with this professor - it's not worth it. Just wait for another professor to teach the class.

Comment: Entertaining as far as lecturers go. He goes a little slow in lecture since he has to write everything down as he says it, so he doesn't always get everything done on time, but he lectures very well nonetheless.

Comment: Sarpong is brilliant and awesome. He was supposed to teach Chem112A lecture, and Robak was supposed to take the lecture, but it reversed this semester for whatever reason. I despise going to lecture and listening to Robak's monotonous lectures, but lab lecture is actually enjoyable solely because of Sarpong. Having said that, lab feels like a completely other class shoved under the label of "CHEM112A" in terms of workload. Lab is 5 hours long, the reports take a while, and the worksheets are absolute hell; the quizzes are a bit difficult, but read his lab lecture notes multiple times.

Comment: The dude is AWESOME. I don't know why he's not teaching the lecture instead of Robak, who is just a complete bore. It's a huge shame because he was supposed to be the lecturer and Robak the lab lecturer, but Robak became the lecturer instead and now I hate the class.

Comment: Lots and lots of carbonyl chemistry. I didn't like the way Sarpong organized his lectures, he does write clear notes for you to copy on the board. Mostly it was hard since it was a LOT of reactions and the patterns/connections between them were not clearly presented in class. Also hard because the tests were mostly synthesis problems. He didn't give problem sets (yay no hw), but that meant we didn't get much practice with the material. He did give in lecture ten minute quizzes that I guess was supposed to make us think about the material before the test, but mostly I crammed for the quiz, failed, and didn't learn much. Lab lecture has short quizzes, but it's easy. Also, lab was easy (with Robak)--- even though it was long, the last hour was usually doing the NMR hw or whatever and there were very few (and easy!) "formal" lab reports. Last thing: Same lab textbook as 3 series, so just borrow it! Pay attention to the patterns -- reactions that work the same way or make the same thing.

Comment: It's hard to categorize the reasons why Professor Sarpong is a great instructor. He's kind of a Jedi master in ochem, although occasionally trolls students mercilessly. Sarpong will lay all the necessary information out in front of you, but you must take it for yourself– there are no required problem sets, and details necessary for answering practice or quiz problems may be found only in the book (notice, he will tell you where to look during lecture, but half or so of the class doesn't really listen). Although the class looks like a ton of material and memorization on the surface, the real substance is a few simple concepts that guide a wiiiiiide range of reactions. It's basically on you (and your visits to office hours) to put it all together. Ideally, you wouldn't be able to memorize the answers to ochem problems, and you would have to work through them using the understanding developed this way. Of course, Sarpong has a funny little habit of reusing old exam questions, EXACTLY as written, and often multiples taken from the same past exam. I do not approve, but on the other hand it may help your grades, which seems fair enough when there are 50% averages. It didn't help mine, but may you have better luck. Synthesis questions and pericyclic reaction questions (end of course) are tough– one way or another you have to "see" it in your head in order to get anywhere, and "seeing" it can become kind of an arcane process (hence the Jedi reference). There is no way to guarantee that you will see the answer to the problem, or the sub-answers that will lead you to the final one. No matter how much you study, the best you can do is trust your instincts, activate your carbonyls, and remember the difference between a proton and a hydride. Maybe you'll see it... and as long as you show that you saw SOMETHING, you'll pick up some points... GSI's are tough but not evil. Then again, maybe you'll remember the answer from exams posted on Ninjacourses. May the Force be with you.

Comment: Upperclassmen made this class out to be a lot harder than it actually was. Sarpong isn't as popular or as laid back as Francis, but he's a solid professor. The material is somewhat harder than 112A (a lot more focus on mechanisms and synthesis, much less on theory). Learn how to do retrosynthetic analysis. He won't teach you. You'll have to figure it out. The worst thing about this class was that there were no problem sets. It seems like a sweet deal until you realize you haven't done a single practice problem all semester. Also, fair warning: he likes to reuse the crap out of old exam questions, so study those.

Comment: Not having any homework is nice. The exams are pretty easy if you're comfortable with retrosynthetic analyses. If you make the effort and *understand* the material instead of memorizing, it's a fairly easy class.

Comment: Do not underestimate this class. The sheer volume of material is enough to be challenging, let alone the actual difficulty of the material. Tests are difficult, but fair. He doesn't pull any punches, but he does get creative. Show up to class every lecture, without fail, or you -will- fall behind. Professor Sarpong is supremely helpful in office hours, and if you come ready to learn, learn you will.
