I dedicated the majority of my time to this class and I genuinely enjoyed taking it with Lannan so much! Dr. Lannan is the best Chem professor I’ve had at UCLA, and he cares deeply about students and he genuinely wants them to succeed. He presents biochemistry in a simplified and digestible way, that still helps you develop a deep understanding of the material. Lannan offers ample resources and opportunities for students to reach out for help, so definitely utilize them all if you can. The campus wire for this class is really active and helpful for answering content questions, (and you get extra credit for answering/asking questions, so take advantage of it!) Lannan’s office hours are helpful if you actively participate, or at least go in knowing what you don’t know. You won’t get much from just sitting and listening, so definitely review the slides, homework, practice midterms, etc. beforehand. His exams are fair, but they definitely increased in difficulty (compared to previous quarters and the first midterm imo.) I highly recommend studying his slides really well as he often expects you to use his same wording on exam answers as shown on his slides. Understanding each problem of the homework, attending the review sessions/OH and asking questions, and engaging with the LA’s during discussion section will help you succeed on exams too. His quizzes are essentially free points, as they are mostly just memorization.

This class is not easy by any means due to the sheer amount of content expected to be memorized in just 10 weeks. I would definitely make sure you have a good amount of time to dedicate to it during the quarter. With that being said, Lannan is a really amazing professor and I would totally recommend taking 153A with him!

This class was by far my favorite ever taken at ucla and that was mostly due to Professor Lannan. The class is especially interesting and I was sad when it ended. Lannan is great at explaining the content and even though he goes fast you're still able to understand. I personally believed the exams were very fair as many of the questions were almost the exact same from practice exams and the new ones were manageable if you understood the content. He also held a lot of office hours and went through concepts in more detail and at a slower pace which was super helpful. He gives extra credit on the exams, through short surveys, and an extra credit project at the end so this really helped too. I honestly have nothing bad to say about him and it really shows how much he enjoys teaching and tries to help students understand the material. Overall, highly recommend taking this class with Professor Lannan as he makes it interesting and enjoyable!

I poured my heart and SOUL into this class and absolutely love it. I don’t know my grade yet but I actually feel like I learned so much so I’m not super focused on what U actually got. Dr. Lannan is very engaging and I loved going to his lectures. I thought I didn’t like biology but I ended up being sad when this course was over. I will say that I thought the exams were hard. The questions are fair with the occasional tricky question, but they are graded super harsh which makes them more difficult than they actually are. His OH are helpful and all the LA’s are super knowledgeable so I benefited a lot from the review sessions. As long as you stay on top of the content, you’ll be fine. Would definitely recommend

Great lecturer. Very organized. To be honest, I feel privileged to have professors as caring as him to teach a difficult course. He really cares about the students as a big group and react to our performance in class. Can't inmagine his efforts in making this class so great!

Lannan is honestly one of the most knowledgeable professors that I have ever met. He is clearly well-informed and enjoys his subject. He can make connections to different real-world situations, and knows everything he is teaching inside and out. He does talk rather quickly, but it is easy to pick up on with recordings. I do think that sometimes he can go off on tangents, but he does have to cover a lot of content. The intense amount of content on the exams is very overwhelming, though. I think that his exams are quite difficult, but the distribution proves otherwise. Not a class for the weak.

Lannan is a good lecturer and makes biochem a bit more intuitive, although I found myself falling asleep in class sometimes, and I found his office hours to be much more helpful. I don't know why he made MT 2 so hard and ambiguous, and I can tell he wrote/printed them like right before the test date because the papers were still warm. He's a cool dude and gives a lot of point leeway outside the exams, which is also nice and stress-relieving.

I loved this class! Lannan is a great professor and deeply cares about his students. He is very approachable for questions both on campuswire, after class, or in office hours. The content was very interesting and the tests were fair. Plus, there is a fair amount of extra credit on exams and a final extra credit group project,

As someone who hates memorization, I was dreading this class because I had heard from everyone that biochem is pure memorization and that I had heard all of the biochem professors are awful. (It also didn't help that I am a transfer student and this was my first quarter). However, I was greatly surprised by how just how much I loved this class. Sure there is stuff to memorize but Prof. Lannon really tries his best to keep that to the minimum and focus on learning and understanding. He has good lectures that are engaging, although he can work on the wording on his slides to make them more informative but they are pretty good. For some reason though I would always feel like I was falling asleep in that class. I am not sure if that was because I had the class right after lunch or what, but it wasn't anything in his power (his lectures aren't boring). His HWs are also very good at showing you what is important and he also provides practice exams which are definitely useful. His office hours are also very useful (only if you have specific questions), but they do get packed very very fast, so you have to make sure to run there if you don't want to sit on the floor. But I only recommend going to office hours if you have a specific question, else it is mostly a waste of time. He is also very nice for having extra office hours (even during weekends) before exams. He also uses an app called "Campus Wire" which is essentially a worse version of Discord but it is pretty good for getting your questions answered. He also does check attendance with iClicker. The quizzes are very simple memorization and should be free points but he does drop one, and also offers a good bit of extra credit. The worst part about this class was just how AWFUL the majority of TAs were. The majority of the time they had no idea what they were talking about and couldn't answer basic questions, this resulted in lots of incorrect grading on exams (thankfully there are regrades though). This also made it so that you had to write ALOT in specific detail for exam questions because the TAs essentially just check to see if you use keywords that are in the answer key. On the other hand, the LAs were amazing and basically knew way more than the TAs, so if you need help definitely as the LAs instead of the TAs. This class is very dense and covers lots of content, so it is important to understand the concepts and not just memorize them as by the time the final rolls around there will be too much to memorize. Also, start studying for exams at least one week in advance and do a little bit each day. I have heard that some other professors go very in-depth with ochem, but in my opinion, Professor Lannon just does the right amount of ochem and biology. I genuinely enjoyed this class way more than I thought I was going to, and I actually learned a lot of biochem. However, be aware that this class is full of tryhard premeds and for that reason, most of the time the averages for exams are very high (for us it was around 88%) so don't expect a curve.

Professor Lannan delivers captivating lectures and equips students with the necessary tools for success in the class. While his midterms may appear challenging, the availability of extra credit and ample practice materials contributes to high average scores. Professor Lannan is notably accommodating and genuinely invested in the success of his students.

Awesome prof. He knows his stuff, he was prepared, and he had a good sense of humor. Overall, content is not difficult, it's just a lot. Exams were fair and often very similar to the practice material. EC was offered.

Would highly recommend!
