A lot of people complain about the professor, but how is it some people get A's? There is a lot of material to cover and so you MUST do a lot of work on your own if you want to understand. His tests were based exactly on practice problems given in class and on practice tests. He is passionate about what he does and sometimes too detailed.

Hersh is not bad. Orgo is difficult, but not impossible. Really understand your acids/bases, Resonance, and also WHY/HOW reactions occur. Study from text and outside resources. TONS of reactions, but exams are definitely doable. Get the ACS guide early, and understand it well. Also, read before class. Study hard, aim high, and good luck to all.

It's one of those classes where you have to pretty much work your ass off to pass and do well but that is Organic Chemistry in a nut shell. It's not easy but start with the right mindset (not looking for an easy professor) and sitting down, reading the book, using online resources and practice. He does curve for those who are border-line failing.

Lots of varying opinions but if u study hard and retake the course 3 times, i can assure you will get an A...anyways two exams 30% each with cheat sheet so do your best on those or hersh will convince you to change career plans since you cant figure out the relationship of a fischer and sawhorse projection.

Don't recommend at all. RUN AWAY!!!! Hersh makes the class a lot harder than it has to be, basically makes u hit the ground running. Orgo is definitely hard and requires work but due to Hersh it's practically impossible. Kids have taken this 3-4 times at QC and failed consistently. Definitely epermit this class, don't stress yourself or hurt ur GPA

The ratings really say it all. He is so rude when you ask a question and will make you feel like a failure for even asking. His exams are either a hit or miss; the second exam was a complete curveball. If you aren't mentally prepared to get destroyed by his exams, do yourself a favor and epermit the class elsewhere.

Nobody takes Organic Chemistry because they want to, they take it because they need to. Yes, the class lives up to its scary reputation. Do not take other difficult/time consuming courses while you take this. This is your life. This course is your entire being for one year. There is nothing else. It's not even a little bit enjoyable.

Not a bad professor, but the class is tough and if you are taking other science classes you need to find a way to study. Had him for chem 251 last semester for Fall 2022 and I have to recommend taking with another professor or going to another school for this class. It is hard all around but the class is hard here.

Smart man, a very dedicated chemist also, but as a Orgo professor like most out there I would pass. Take at your own risk, many relied off fancy tutoring services with his old exams (he should consider changing exam formats/question types) because this was how many got through. I would suggest taking elsewhere because of these things.

Recommend to take this at another school. Orgo is orgo, but this class with hersh is haywire. The final has nomenclature, knowing the bp/mp of certain solvents, and mostly synthesis. The class is not a reflection of orgo's true beauty, sad but most who pass (like me) still have no orgo knowledge but can take biochem.

This class is unlike any class I've taken before. Come to class prepared because there are no slides-you learn the material as the course goes on during lecture. Hence, you have to read the textbook beforehand to understand the material. Is it possible to get an A? Yes, it's possible without tutoring, but get ready to make sacrifices for it.

Hersh is out of touch with the students and times. Should have a TA in class helping, or flatly be in charge of orgo classes only as his class becomes a "cheat my way through this".

I don't think it's a class you can get by in by just listening to lectures. You should really put time into reading the text and doing a lot of practice problems and applications.

Is there a reason he hasn't changed exams up year by year yet? Letting students get away with murder who go to Nomi or Orgo-man because they have past exams. The class is not "up to standard" if he lets these students get an easy pass while others struggle, and certain cliques take that tutoring service, and interpret as you wish. Take elsewhere!

He's very good. The truth is you don't need any tutor to do well in the class. Take his lectures, recitations, and textbook seriously and you'll be more than passing. Half the class doesn't even come to lecture and then complain that he's no good. Going to grad school requires some fundamental study techniques and discipline. Underrated professor.

Tutoring is not going to guarantee you a pass. Coming from someone who took Nomi, It was still required for me to put minimum 20+ hours a week into studying, while attending all lectures and recitation. To succeed in this class, use reactions that are posted on blackboard and DO HIS SAMPLE EXAM QUESTIONS!!(As some of them are similar on exams).

The influx of good reviews is strange, almost like a cover-up. Whatever it is, he's a nice enough man, but he should change exams up strongly for the sake of fairness.

William Hersh is a great and honorable professor. This class is not very hard to do well in as long as you put in the right effort and stop worrying about others (and the fact that they have a tutor). There are so many resources available to you (text, office hour, lecture), you don't need to waste thousands of $$$ for a tutor to get a good grade.

Both organic chem 1 and 2 are difficult. His class and tests are designed to trick you, it seems like he aims for low grades with his students, and blames students for lack of studying/reading for their bad grades. Tests are short response but hardly gives partial credit, seems like he wants to take off points to just take them off. Terrible.

It turns out that I'm in the minority, but Dr. Hersh is amazing. He's great at explaining concepts, he's always very helpful, and his tests are fair. The subject is relatively easy (except for the garden-variety carbonyl compounds which were loaded with reactions). Go to lectures and pay good attention. You. Don't. Need. A. "Tutor". To. Do. Well.

Sorry to the fellow readers who see the weird beefing. Hersh is decent, but as a professor that differs. The more past material you have the better, any former student will tell you he gives samples from the year prior, but some have more for reasons. Not fair, would be best to truly revamp exams. Advice? Use Orgo as a second language and practice.

Sample questions are not enough, even Hersh says this on his syllabus that you have to truly integrate with the material. Relying off that only is bad news.
