Lannan wasn’t the best professor, especially in the beginning, but if there was a “Most Improved” professor award he would easily win it. He just got thrown into a difficult situation teaching the class for the first time on really short notice, and it showed in the beginning. However, he always ended up addressing his mistakes and the lecture quality was actually really high. The class is just really hard and many people are upset about the fact that they had to memorize things when last year everything was online so you could just use a cheat sheet. Were there issues with grading? Yes, but he literally just gave out free points and people still complained. Most of the mistakes were due to the TAs anyway, who were far more disorganized and lazy than Lannan (they promised to finish grading and ended up delaying multiple times), who ended up taking all of the blame. He’s actually a really funny and engaging lecturer who I would take the class with again. Don’t listen to the reviews that say he’s terrible and disorganized and hates all his students, he just didn’t know how to manage everything and got it figured out. Everyone just wanted Jarrett because she gives easy tests that won’t prepare you for the MCAT at all, but you’ll get that A+ because you don’t have to memorize anything!

Lannan was an amazing Biochem professor. Biochemistry is a tough subject and the professors are not known to be that good. Lannan is the exception, and he's pretty new so he'll only improve each quarter. Here's a breakdown of his class:

- Participation through iClicker and Discussion (6%), Quizzes (10%), Weekly Homework Assignments (14%), 2 midterms (20% each), Final (30%)
- He uses Bruincast and you don't have to be in the lecture hall to do iClicker
- Discussions are very helpful. They go over homework problems, so you're basically doing part of your homework there.
- Quizzes are strict memorization and pretty easy. There are 5 over the course of the quarter. You can drop your lowest quiz
- Weekly homework assignments are tedious, but easy. They're great preparation for the actual test questions and he only grades like 2 or 3 questions on correctness. The rest he gives full credit for as long as you submit it.
- Midterms are NOT during class time, but rather at night. You're given an hour and a half, but you can probably finish within the hour. He gives a couple extra credit points on each test, too!
- Overall, as long as you keep up in lecture and do some basic memorization, this class will be easy. Lannan is very helpful and responsive.

He also gives 0.25% grade boost for doing LA and Professor feedback forms.
He has a 1.25% Extra Credit group project in week 10, too, where you use your biochem knowledge to create your own organism.
Would definitely recommend him to take your Biochem requirement.

This class is hard. That is undeniable. However, I would say he has made a lot of improvement since the course he taught last winter. Though the exams are difficult, there are no curveballs thrown when it comes to questions; all of the information is on the slides or was mentioned during lecture. If there is something that the students felt was unfair, then he takes that into consideration when grading. This is a class that you have to be 100% all in for because it is a lot of information (4 lectures a week). That being said, he helps out a LOT wherever he can. He offered a ton of extra office hours and had a lot of leniency during the TA strike. He offers a good amount of extra credit as well. Of course, that doesn't mean everyone will get an A. The effort you put in will show in the end.

As a person overall, he is amazing. You can tell he is someone who cares about the students and cares about getting people the best grades possible. My schedule this quarter was rough and it was also my first one since I am a transfer so I didn't have a lot to look forward to. If I am being honest, the only thing I looked forward to was this class. It was the only class where I didn't have a grudge against my professor and where I actually liked the material being taught. I nearly wanted to change my major but I realized that the only reason I would consider biochemistry is if he taught the other courses. He is super relatable as a person and quickly became one of my favorite professors. Definitely take him.

Lannan is a great professor. You could tell that he actually cared about us and he was great at accommodating us. He literally has multiple office hours a week and the week before the exam he had at least five office hours. He is actually really funny and relatable once you get to know him, and once you get used to his style of teaching his class is very straightforward. Tests were fair imo, and the quizzes are very straightforward - just memorization. There are no discussion worksheets, and most of the homework were graded on completion. Please take him if you can! This class made me want to change my major. I loved it so much and I was shedding tears once it was over.

The class was really difficult. He would give the study guides about 3 days before the exams and he graded them so harshly that you have to have specific words in your answers to get the points. This class would be good if your taking it by itself since it’s a lot of work. Homework and quizzes were pretty manageable and he does offer 2% extra credit. But I would not take this class again since his lecture slides does have a lot of mistakes on them and the exams were graded wrongly.

I really enjoyed taking this class with Dr. Lannan and I would recommend him to anyone who wants to 153A. It was his first quarter teaching the class and he got assigned very last minute, so he did not have time to prepare slides, tests and everything like that.

Here is the breakdown of points:
Midterm 1: 20%
Midterm 2: 20%
Quizzes: 10%
Homework: 15%
Final Exam: 35%
Extra credit: 2% (campuswire =0.5%, evals = 0.25%, ec project = 1.25%)

He gave around 3% of extra credit problems on tests and these were all just free points. He ended up curving the final 6%. His tests are very fair and reflect the hw problems and are all pulled from the topics on the study guide. This class does have a lot of memorization, but that is the nature of 153A. If you stay on top of it and review his slides, you will do well in the course.

I thought Dr. Lannan was a great lecturer who was truly fair. He is clearly very knowledgable on the topic and I thought he did a fantastic job and I think he will only get better over time. Dr. Lannan is fairly understanding and communicates well.

Also - he offers this online textbook with practice problems called Achieve. I did not purchase it and I was completely fine. He never references the textbook and gives sufficient practice problems with the homework. If you like extra help, it may be for you, but I wouldn't purchase it until after week 1 when you know how the class works a little better.

Overall would take again and I highly recommend Lannan!

I would not take this class with him again

On the Thursday of week 10, he not only did not post the final study guide, but also sent out the last homework at about 9:00 pm. Why?
Remember to write exactly the same words from his slides and homework answers, otherwise you will not get the point in the midterms and the final.
He said it was his first time teaching this course, so it took him lots of hours to gather the information and made the slides, so his lectures are a little bit disorganized. Guess what, it is also my first time taking this class, and that was definitely not a good experience to me.
Also, tons of homework. The first several homework were like 9-page short, no, long answer, questions. He would ask you to draw the whole mechanism of RNase and chymotrypsin. Very good! Moreover, he is like "You don't have to remember everything in the mechanism, but if we give you one step, you should be able to predict the next step." How is that not memorizing all the mechanisms?

我上这节课的唯一原因是一开始153A是一开始study list上显示这节课是Deborah Jarrett教 我听说她教的不错，所以选了这个课 谁知道真正开学之前换成了Ryan Lannan

事儿很多 不会选他的别的课了

Honestly, the people roasting professor lannan are just upset about their grade. This man is incredibly accommodating, like I have shown him mistakes and made criticisms and he LISTENS and truly makes changes. He is a super nice guy who was just put into a tough position this quarter.

He knows how to teach biochemistry, like this class honestly had very interesting material that was easy to understand once he broke it down. Yes you need to study for exams, but if you do that you will get a good grade.

The TAs of the class were the main problem tbh they did not know how to grade, but if you brought it to Lannan's attention he fixed it almost immediately.

it is week 6 and i decided to drop this class. This is by far the worst class i ever took at UCLA, Lannan is the worst professor. poor lecturer, disrespectful, and very hard grader. he does not know how to teach and himself doesn't know the contents well as his slides are full of mistakes. the tests has nothing to do with what he teaches in class, extremely hard and very long. the homework are also hard and were harshly graded, he even deduct points for students who didn't assign pages to the grade scope. PLEASE LOOK SOMEWHERE ELSE. DO YOURSELF A FAVOR DON'T TAKE HIS CLASS

Ryan Lannan is the worst professor I have ever taken at UCLA. It seems like he doesn't care of students and comes across as dismissive. I wish he was a lot more like Anish Nag. I was really looking forward to this class but now I dread it.
