I think the professor is a great lecturer and does a fantastic job of explaining the content in a way that is digestible to the students. That being said, I think the way that the exams were graded were honestly ridiculous; you could put an answer that is completely correct but if you do not explain it in his words or use specific terms that he feels is important then you will get points off. I thought the difficulty of the rubric for the exams ruined this class for me, as well as the fact that there were little to no accommodations for this course given the stressful circumstances of campus this quarter. For every single one of my other classes, my professors had made accommodations to help ease stress and anxiety among students, but professor Lannan does not care about his students in the way that my other professors have shown to care. Overall, professor Lannan is obviously extremely intelligent and knowledgeable about the course content, and he is a great lecturer, but I feel that being a great professor is more than simply being able to eloquently teach difficult concepts, and I think Lannan could have been a better professor if he prioritized students' mental health and wellbeing.

Honestly overrated as a lecturer with some of the most poorly designed tests I have seen. His rubric is extremely subjective to the point where TAs disagree with him. I honestly would not recommend this professor.

Chem 153A isn't going to be easy and there's a lot of material to memorize and understand but Lannan did an excellent job at teaching material during lecture and his tests were incredibly fair and manageable. He also provided a lot of extra credit, making it easy to do well even in a notoriously hard class. I highly recommend.

Went into this class knowing it was going to be difficult and I would need to put in alot of effort, however I personally think this class is not set up for you to succeed. Professor Lannan is nice, but I found his lectures to be extremely confusing. It felt like he was trying to verbally figure out what he was saying, as he was lecturing, and he would always backtrack and have to reword his thoughts. He rushes through the material in class rather than making it digestable and focusing on the quality/organization of his explanations. The homeworks are graded on accuracy, but theyre not too bad, and the quizzes are memorization (so easy points). However, the exams are a whole other story. Biochem is generally ALOT of info for a quarter class, but the information expected of you to master for the exams is overwhelming.

Lannan provides learning objectives with topics to focus on and he claims they are helpful, but they still dont give you a good idea of what to expect from the exam. He provides old exams which are practice, but I genuinely think that the practice exams were always easier than the exams he wrote for our class. He would give SOME repeats, but for the most part you need to master ALL the info. Our second exam was horrible because it was the length of the final, but we were only given 'midterm' time, so the time crunch was unreasonable. The exams also felt like Lannan was trying to make them harder from previous quarters (students from previous quarters agreed). Something else that was disappointing was that Lannan claimed for the exams to be fair, and that students that put in the effort would be able to succeed. I completely disagree with that because myself and other students that put in excessive effort, still did not get a grade on exams that correlated with their efforts and intelligence.

Lannan also walks away from students as they are asking questions, and office hours feel like youtuber meet and greets (too many try hards). There are no resources to really succeed in this class, aside from your TA, but thats only even helpful if you get a good TA (mine was whatever). Discussion was also pointless (attendance was mandatory tho), you just do homework but my TA could never really explain things well (I heard the same about a few other TA's).

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.
