Lannan definitely improved a lot in his second quarter of teaching. He got a lot of hate in the winter for his slides, but he made his own set for this quarter, and they're incredibly clear and to the point. He's a good lecturer, and you can feel how hard he works to make the class manageable. The midterms themselves were fair and very much based on his learning objectives. He was also extremely accommodating for the final, considering the TA strike situation. I would recommend taking 153a with him :)

Lannan very clearly cares for his students and their performance in his course. He is very open to criticism when it comes to exam difficulty. This class is definitely meant to be hard, but he teaches it well. I find his exams to be fair and he even offers extra credit on some.

I am still in his biochem class. I'm retaking biochem from summer which I just didn't go to class and didn't pass. That summer version was SO simple and manageable looking back - the professor seemed like they didn't want to play with you. Just get straight to the point and take your grade. Grade was based on max 3 things - the midterm, final & zoom participation. DR. LANNAN MAKES THIS THE MOST COMPLICATED, HYPER-SPECIFIC GRADING RUBRIC I HAVE EVER SEEN. POINTS COME FROM EVERYWHERE, AND ITS BASED ON A 1000 POINT SCALE???? WHY?? HE IS A HOT YOUNG PROFESSOR WHO REALLY WANTS YOU TO LEARN BIOCHEM BUT ALL WHILE MICROMANAGING THE WAY YOU DO IT. I DON'T NEED HOMEWORK ANYMORE AND WHY DO I HAVE TO BE IN YOUR PRESENCE TO RACK UP POINTS FROM YOUR UNNECESSARILY FRACTIONED SYSTEM OF MEASUREMENT. HE'S CUTE BUT HE'S DOING TOO MUCH RN. I'M PROBABLY GONNA GET A D OR C HOPEFULLY NOT F.

Lannan definitely learned from previous constructive criticism from past quarters. He is a great lecturer and is very nice and approachable. He knows how to teach the class very well. The material itself, however, is super difficult. His homeworks are reasonable and his midterms are semi reasonable. The grade breakdown goes as follows:
Midterm 1: 20%
Midterm 2: 20%
Quizzes (Memorization): 10%
Homework: 12%
Participation: 8%
Final: 30%

Worst professor ever.

A lot of these reviews on BruinWalk are on the opposite sides of the spectrum. But in my opinion, I thought he was a really good prof. In the beginning it was definitely rough but it was his first time teaching this course so I'd cut him some slack. He did a whole 180 around the midpoint of the quarter and his lectures became much more engaging and had a lot less mistakes than the beginning. Some issues is that the slides sometimes had mistakes and that we would go overtime really often. I was in lecture 2 so I think the complaints that lecture 1 had about him is definitely fair. Hope he gets to keep teaching this class in the future since he shown a lot of improvements in his teaching style!

The tests were fair and the averages were decently high, but so many of us had to sell our souls to get there. I understand that it was Lannan's first time teaching this class so future classes probably won't have as many of the same issues with him providing resources late (if he provided them at all) and constantly contradicting himself. Do not take this class if you want a life and/or you are bad at memorizing. You have to know every single word he speaks in every single lecture (slides alone aren't enough to get an A unless you're reallyyyy good at bs-ing). I did well and actually liked the material, but I spent so many nights crying from stress and frustration and also had to miss some events I really wanted to go to. His ego and pettiness was also annoying

Lannan's interest in biochemistry shows and I actually did learn quite a bit from his class. However, there are many things in the course that need to be addressed.

Lannan needs to be much more concise in lecture. If he was more concise with his explanations, this would prevent him from constantly going overtime and would allow him to answer some student questions. He also mumbles a lot at the end of his sentences and makes an extreme amount of typos in his slides. I highly suggest he review his slides before publishing them. Furthermore, I’m in lecture 1 and many times he has told lecture 1 students that he explained concepts better in lecture 2, so to go watch the recording of lecture 2. He just needs to prepare his lectures in advance. I would also prefer him to post assignments and study guides with adequate time for students prepare. He also doesn't react well to the grading mistakes he and his TA's make. I was lucky enough to get my regrade requests in before he made the process more complicated. He also did give out extra credit. In the end, he curved the class, which was a relief. But there was a lot of unnecessary confusion and stress from the logistics of the course.

I think the negative reviews for Lannan are so unwarranted. I think every professor for this class would be harder than Lannan and way less generous. He was concerned with student learning and his slides were very good considering it was his first time teaching the class. The homework helped me personally and the quizzes were necessary to memorize the content. The class is just memorization so it’s not that hard as long as you put in the work. Overall good professor would take it with him again any day.

A lot of people wrote mean reviews about Dr. Lannan, but I think a lot of people were unfairly judging him just because they did not do well. Honestly, biochem is known to be a class based upon memorization, so a lot of the people that were complaining weren't taking that into account. Although Dr. Lannan was a bit disorganized at first, his lectures got better and better throughout the quarter. Overall, I did feel like I learned a lot and that Dr. Lannan was a pretty good professor to take 153A with.
