Conley is amazing and really knows how to teach. Everything is very simplified and his tests are almost identical to his practice exams.
His second midterm did catch me by surprise as it was stuff that we covered in class very briefly so watch out, but other than that everything else was pretty straight forward. Going to miss his class

Amazing professor! Writes down everything on the board which makes it easy to copy down notes and learn the process. His exams are very similar to the practice tests.

Conley is a god.

I had Conley for LS 30 A & B and he was pretty good. I felt the overall concepts taught in this class were easier than other math courses taught at UCLA. His midterms were definitely easy and the first midterm probably involved more writing than math, like knowing definitions and explaining a concept covered in class. I really liked the fact that he held super long review sessions before each test. But it was kinda unfair for students who weren't able to make it b/c I felt as we were approaching a midterm, he'd always rush. So at the review session he'd either cover a concept we didn't mention in class OR clarify something we went over really quick in class since it was gonna be on the test. But I felt it was unfair for anyone who didn't get this extra help if they didn't have enough time to make it to his review sessions. My only real complaint would be about the final though. I got A's on both midterms b/c they were literally just like his practice exams. But those trick you b/c the final was formatted to challenge you more. Which I get b/c this is still a college course but I didn't feel prepared for that extra challenge given the fact that the midterms were so easy and EXACTLY like the practice exams. Anyways he seems really interested in helping students and I don't think I've met another teacher who holds 6+ hour review sessions. He never seems to get tired. Anyways yeah I guess I would take it with him again

Conley's teaching style is very organized, and he makes it easy to connect concepts. He is also very willing to help, often having review sessions from 6pm-11pm.

Just here to reinforce good reviews of Conley. Really helpful especially in office hours.

Probably the best lecturer I've had so far in UCLA. To be honest, I went through a lot of LS30A not understanding what the purpose of the class was. But with Conley, he made everything I learned in LS 30A so much clearer from just the very first day in LS 30B. He was really good at explaining the topics in simplest way possible, and his notes on the whiteboards are super easy to follow. I could copy them down and remember exactly what he said when I look back on the notes. He also makes sure to show us how one thing connects to another.
The labs/coding can be tricky, but it actually makes a lot more sense once you get it because he briefly mentions during the week's lecture what the lab is suppose to show regarding the topic.
His review sessions are super helpful. They take a while, as he goes over ALL the material in a condensed form, and he takes all the time necessary to answer the students' questions. It's really nice of him to take the time to hold review sessions as a professor instead of just pushing those to the TA's.
Overall wonderful professor, take him if you can.

Take the LS30 series. Don't take the 3 series. TAKE CONLEY. TAKE CONLEY. TAKE CONLEY. Professor Conley was the best professor I had during my entire freshman year at UCLA, and I am sure he will be on of the best during my years to come. It is clear that he is there to make sure his students learn and know the material inside and out. I personally loved LS30B much more than LS30A. The course as a whole is very interesting and not too difficult at all as long as you take the time to review the material. His review sessions are LEGENDARY!!! He will take the time to reteach all of the material relevant to the upcoming exam in a manner that connects all of the bits and pieces together. Conley's review sessions for the first and second midterms were at least 4 hours each, and he is always willing to go as long as needed so that all questions are answered. For the final review session, he almost went for a full 6 hours. This man is absolutely amazing. You will not regret taking his class; it will make your freshman year so much better.

This class along with LS30a have been, so far, the most interesting classes I've ever taken at UCLA since I, like many if my LS peers, despise calc. If you're not a math person, take the LS30 series rather than the math series (why suffer?) If you want the get the best grade possible, do your very best to get Conley as your professor because his lectures are engaging, you can see his passion for mathematics, and his care for our success is evident. If you get him as your professor or not for either LS30A or B,, make sure to attend Conley's review session because he answers literally every question the students have, goes over nearly all of the new material we covered, and shows us numerous examples by hand or on sage. Furthermore, the concepts of this class, especially feedback loops, give you a headstart on concepts you'll learn in other life science classes.

Basically, I highly recommend Conley and encourage you all to take his class.

HE IS AWESOME. I'd say choose him over any other professor.
Here are reasons why:
-He is very clear
-He teaches at an appropriate pace
-He answers question well
-He is not monotone or boring
-Although there is always a curve ball question, he prepares you for it.
-His review session is literally him reteaching everything and does not care if you have a million question he will stay until 12 am just to help
-He's just super nice in general

Reasons to not take him:
-there aren't

Side Note: LS 30 series is more conceptual than calculations needless to say my mid-terms and final had more writing than math.
Pro: In the end, you really understand concepts.
Con: You can't BS, there isn't a magical equation where you just plug things into.
