Don't be scared off by some of the horrible ratings for Prof. Reilly. First of all, Chem 14D is a hard class-Organic Chemistry is a hard class. There are a LOT of reactions that you have to memorize, and the amount of material really picks up after the first midterm.

Professor Reilly is not a bad professor. She is slightly disorganized; she doesn't personally respond to emails (but she addresses questions in the next lecture in person), she posts problem sets and Gradescope assignments late, and posts answer keys with wrong answers sometimes. But, she does care about her students.

For our second midterm and final exam, she literally told us which reactions we would have to know the arrow pushing for (2 mechanisms for the 2nd midterm, 1 was tested; 4 mechanisms for the final exam, 1 was tested), and that was basically an automatic +20 points on your exam. She also provided plenty of extra credit assignments that were quite fun (we drew her dogs for one, and then made a meme of the class for another); these compiled up to around 8-10 points.

Her online exams from past quarters were MUCH harder than her in-person exams. She provided past exams as practice exams for our midterm and finals. After taking her in-person exams, it's very clear that she made her online exams (open-note) significantly more difficult than her in-person (closed-note) exams.

According to other students, she also curved the class, but I didn't calculate my grade percentage so I'm not sure how much she curved it by. However, I went from an E on my 1st midterm to an A on my 2nd midterm and final and ended up with an A-.

There's a lot of tweaking that you have to do with your studying habits-- THIS IS NOT A CLASS THAT YOU CAN PROCRASTINATE IN!

This class requires lots of practice. I would advise you to get ahold of summary sheets before week 3 and start memorizing and understanding those reactions, as she takes a long time going through SN1, SN2, E1, E2, etc. Also, go to her office hours, she will teach a lot there and answer the questions you have. But all in all, memorize, practice, and make those flashcards!

Dr. Reilly is the best professor I have EVER had. She wants students to succeed and her positivity and kindness really helps you get through this difficult subject. Her midterms and finals are very fair, and she has helpful discussion worksheets which are the best way to study for tests. Class is not curved, but she does adjust the grading scale. Our averages were low 70's and high 60's for midterms (making the average a B-). The final was around a 78 because it was a much easier exam. She gives extra credit for clickers and for evals. We had a few assignments on BACON which were worth 9% of the final grade. Go to office hours!!! She is amazing at explaining, especially when she can go step by step with you. I also took her for Chem 30B in Winter 2019 and will take 30BL in the spring. She continues to amaze me. If I took this class with any other professor, I am pretty sure I would have switched my career path by now. Bless this woman!!!!

Took her for both 30A and 30B. Prof Reilly will guide you through intro to ochem pretty painlessly as long as you put in the effort, i.e. go to class and office hours, do the practice problems, read her lecture notes, summaries & other materials carefully before exams, and actually try to learn and understand. Imo she paced material pretty slowly and covered material clearly, and knew well that most people were completely new to ochem. Her tests were very fair and she gave a little bit of extra credit for lecture attendance and for exams. She posted meticulous handwritten lecture notes before lectures and personally I found the annotated lecture notes she uploaded after lectures the most helpful for revision. I personally didn't go for office hours but I could tell she definitely cared about students and their learning. Would recommend her for CHEM 30 series for sure.

Professor Reilly truly made this class more bearable and her humor/in-class demonstrations always made lectures engaging. I have left this class feeling like I truly learned a lot and I actually did appreciate most of the structure of the class. Chem 30BL does genuinely give you a glimpse into chemistry research and applications. I went to class/lab finally feeling like my TAs and professors gave a shit about me and what I learned, in a subject I loved.
It's adorable that they give tours and stuff to see NMR spectrometers and the DART MS instrument. The demos Reilly gave in lecture could be hilarious, too, particularly the second polymer lecture. She literally just got one of the TAs to bring in polymers to demonstrate glass transition using liquid nitrogen and broke a ton of stuff. I sat in the front row and nearly got attacked by a hardened piece of rubber tubing LOL.
With that said, it is not particularly easy to get an A in this class given the 95% cutoff - and don't count on there being a curve. I asked and she told me she's never curved this class (since she started teaching in Summer 2018), and it's because no one really gets C's. "If anything, this class could be curved down, but I would never do that" is what she told me. I really respect her so I was never going to argue with her, but ... the flaw of this argument IMO is that the grading scale gets more generous as you go down but is slightly harsh at the top.
Our average for the final exam was 77, but I don't see why it couldn't have been higher if you truly practice. She didn't ask almost anything more difficult than what was in the lecture worksheets.
Grade breakdown:
Pre-labs (20%): 160/161
Post-labs (20%): 187.5/191 (including +2 extra credit for course evaluation)
Presentation (10%): 28/30
Participation (5%): 7/7 (?) or 100%. Not sure if they didn't count a couple weeks.
TA points (10%): not posted yet, but presumably near 100%
Final exam (35%): 94.5/100 (including +1 extra credit)
Overall: ~96.92% in the course (assuming 100% in TA points, could be a bit less.)

Reilly is very passionate about the class, and she often shared about her experience in the field. This class is in no way "easy", but through the help of Reilly and my TAs, I found the class very enjoyable. Each week, you have a 1 hour lecture with Reilly and a 4 hour lab with the TAs. However, most of the labs did not take the full time. For the one week labs, you have a pre-lab and a post-lab due. Most of the lab write-ups are straight-forward, requiring that you report your data and analyze it. A portion of the lab write-up includes a "digging deeper" section, in which you google some information related to the lab and answer questions. The TAs are picky with the grading, so try to be as clear and thorough with your responses. I was able to get mid 90s to 100% on the labs, where I lost most of my points when processing my NMR data. You also need to do a presentation about one of the labs at the end of the quarter. There is no midterm, but there is a final exam. The final covered the material rather evenly. She prepares you well by posting worksheets for each lecture's material and exams from past years with answers. Her class is straight scale, and it is quite difficult to earn an A in the class because if you are not careful, you will lose points here and there and that builds up. She is very helpful in her office hours especially if you do not know how to read your NMR spectra. She also showed many demos in the lecture, which were interesting. I learned a lot about the applications of organic chemistry to different fields, and I would highly recommend this course to those who are looking into research.

Chem 30BL is more interesting and applicable than the other lower div chem labs (20L, 30AL). Each week, we had a different theme (forensics, pharmaceuticals, biotech, etc) and the lab that week was based on that theme. Some cool things we did include using carrots to catalyze a reaction, synthesizing a drug that is used to treat Parkinson's, and "recycling"/depolymerizing the PET plastic in water bottles. While the labs themselves can be tedious (you will probably be sitting around for the reaction to occur), it's really nice to see how applicable organic chemistry is to real life.
Reilly was a pretty good professor for this class - slides were clear, and the lab assignments were mostly straightforward (they're all on worksheets).
In regards to grading, you'll need to get a 95% in the class for an A and a 90% for an A-. It's not too hard to do well on the labs and other non-exam items in the class, but the final (35% of the grade) was rather challenging. Thus, you really do have to study for the final and make sure you understand the concepts well. It's relatively hard to get an A in this course, but not too hard to get a A-/B+.

Take her, trust me

Professor Reilly is a fantastic professor. She is clear in her lectures and ensures that students understand the material that is covered. The class itself is structured a bit differently than previous labs, in that it more resembles things that an organic chemist would actually perform in a lab. So expect a lot of reaction monitoring and a lot of waiting for the reaction to run to completion. In my opinion, the worst part of the class were the pre- and post-labs, which are relatively short but ask questions that can be tricky to find clear answers to. Professor Reilly talks about the questions in class, but those that have their lab sections the same day as the lecture will find it frustrating when trying to complete the pre- and post-labs before lecture.

She doesn't have midterms, and she hosts a review session before the finals that I would highly encourage you to attend. It's informative and very helpful.

She's also very caring about the learning of her students and is very willing to help out and discuss matters if students approach her.

Professor Reilly is the best. She even makes video answer keys of herself explaining the worksheets.. She also has extra office hours every week to help with additional questions. Her notes are super clear, and herself is just very good at explaining and clarifying things. Chem 30A is definitely not the easiest class, the concepts are not challenging but it takes a lot to get used to. I would definitely recommend to take advantage of every opportunity she offers to ask questions. It’s important to build a strong foundation in Organic chemistry, especially if you are chem e/chem/biochem majors. Overall, I’m very glad that I had her this quarter:) She made O chem so much more interesting and exciting!
