hi I'm not taking his class but my roommate is and professor lannan has ruined her. she always cries now and when I ask why she just mutters "I want my tears to lan on lannan." he's really bad apparently, do not take him.

Y’all are being some pussies and are pissed that you didn’t get the grade you wanted. I’m assuming this is also because people are not used to in person exams anymore and are mad 80 percent of the class didn’t ace the midterm. If you study the right way and actually understand concepts rather than memorizing facts by putting in a little bit of time, you’ll do well in this class. Lannan is literally an amazing lecturer. He explains concepts extremely well and goes through things in different ways. Also he takes feedback very seriously and actually makes changes. He made midterm 2 a lot more reasonable then midterm 1 (MT2 average was a 89 and MT1 average was a 75, but that increased when he gave people points back). The only thing that is sometimes annoying is that his test asks “what term is used to describe this”. Even though I can explain the process being shown, he is looking for unreasonably specific answers that most people won’t think to write. Other than this, his study guides are literally so helpful and organizes his lectures. Gave 2 percent extra credit. I think he did an amazing job for first time teaching this class. I loved the class and would definitely recommend the professor.

Please do not take this class. The professor has no clue how to organize his class. He is very disorganized, messy, and unprofessional. I am seriously sad that UCLA has decided him as a professor for such a big class. He is not ready for teaching and educating students. Tough tests, harsh grading, unreasonable point deductions, unreasonable extra credit option (which of course you will not succeed to get the benefit), and...... He keeps saying sorry and sorry during lectures because he doesn't even know what is going on with his slides. He used Prof. Gobber's slides and information and is teaching based on them, therefore he has no idea what each slide is even talking about. When students ask him questions, he avoids answering them, and if he does, the majority of the time he does not know the answer. He keeps saying do not worry about it. BUT HEY I NEED TO WORRY ABOUT IT BECAUSE I PAID TUITION TO LEARN !!! He is confused about simple math facts (which one is a bigger number from -1/5 and -1/3)???? I am seriously shocked how he became a professor. I do not even know why people disagreed with other comments, but he is not definitely someone you would like to take as he is a serious GPA and quarter ruiner.

I thought that Lannan was a pretty engaging lecturer. It was sometimes all over the place but he was clear about what he wanted us to know and the extent to which he wanted us to know it. He also tried to explain a concept in more than one way to try and help students understand. Before midterms, he sends out a detailed study guide of everything we should know for the exam. So I thought the exams were very fair in terms of the questions reflecting the content that we learned. When a lot of people got marked off for not having specific key phrases in their answers on the first midterm, he went back and gave everyone some points back. He was also super helpful during office hours and always went over time to try and answer everyone’s questions. Overall, I think Lannan is a fair professor and I enjoyed the class!

I actually wanna thank Lannan for restoring my faith in God cause after taking this class, I never wanna go to hell again. Seriously the worst class I have ever taken at UCLA, avoid him if you can. Tests were graded so harshly, he expected us to read his mind or something. If you didn't use specific words you got the question wrong. He would even take off points on the homework if we didn't label PAGES correctly,,,he's just overall ridiculous. Dumped new content days before an exam, gave homework due right before/on exam dates...the list goes on. Also, the final was 4 weeks of new material + cumulative which is just way too much. I get he's a new professor but seriously this class ruined my gpa and mental health lol.

Dr. Lannan is a very strange professor here at UCLA. No curves, no mt drops besides a quiz that barely has any impact, and even homework is graded. Your extra credit only wimps out a measly 1.25% and ITS GRADED lol not to mention its an entire group project. His lectures are alright at best, but do not rely on them for the exams alone. His grading is absolutely awful, you will get marked down for the microscopic details you miss or do not explain to his liking and arguing with his rubric can actually lower your grade if you submit a regrade request which is a policy I never seen. Basically, if your answers are not direct quotes from his grading rubric you will not receive full credit. You can basically put the exact answer you see on a practice exam but if it does not match with his current rubric its over. I absolutely loved the content of this class but I dreaded his grading so much and did not receive the grade I wanted. Discussions were helpful, but I do not recommend this professor for how harshly he grades and how reluctant he is to cut some students some slack considering how difficult this subject is and can be.

Honestly, this class sucked. I got a good grade in here, went to office hours and studied like crazy, so please don’t think im just salty about my grade lol. The dude is just super unorganized and seems confused a lot of the time. Does he know his biochemistry? I would sure hope so, the dude has a PhD in it! But let’s be honest, that doesn’t mean you should teach it. Yeah we get it, he got “unlucky” this quarter but it kinda sucks when my professor’s incompetence affects MY grade. The first midterm and final were a complete disaster. Honestly were they hard? No, not really. But i (and my other 500+ classmates) dont appreciate getting points off when we LITERALLY wrote the correct answer (not even exaggerating). Yeah this could be solved with a regrade request, but OH WAIT!! Theres no regrade requests for the final! Yippee!!! So now my hundreds of classmates and I are jipped USELESS points for literally NO reason. Things were very unorganized and honestly it really didn’t seem like he cared that much about our concerns.

Bottomline, if you're looking to take this class in like 2035 or something when he doesnt confuse himself in lectures/office hours, doesnt have mistakes in his lecture slides and just has a speck of competence- go for it. Its honestly not that bad (if you dont get points off for writing the correct answer). But if you’re looking to take this class within the next like 6 years, may God help you. You’re gonna need it.

As a fourth year who is just about to graduate, I never thought I would write a Bruinwalk review to be honest. Reading through Dr. Lannan's reviews on here changed that. I first took Dr. Lannan's 153A class in Winter of 2022, but dropped early on due to family stuff. At the moment, it was his first time teaching 153A and although you could tell he cared about teaching and the student's success, he seemed pretty overwhelmed at times during lecture. But really, that would happen to ANYONE.

Fast forward a year to this quarter, I thought he did a complete 180. His slides are incredibly clear, honestly, probably some of the best slides I have seen in my four years here. They have absolutely everything you need for the exam and they as a visual learner, when the words weren't enough, the pictures on the slides really helped me figure everything out. His lecturing skills also greatly improved since 2022, he was clear concise and I thought he did an incredible job explaining everything and answering any questions students had. Some of the reviews about his lecturing on here honestly dumbfound me because they are just so far from the truth.

Now the part that everyone seems to be complaining about on here: the exams. The exams were not easy. But like, obviously, we its an upper division biochemistry class at UCLA? There was a lot of information you had to know for each test, but the good thing was, all the information you had to possibly know was on the slides. On top of this, Lannan supplies the class with homework questions that look identical to the exams, week by week learning objectives detailing everything he could ask on an exam, and literal exams from past quarters that we could do as practice. People bashing Lannan on here simply did not put any effort into studying and did bad on the exams. He literally gives us the type of questions he will asks and his rubrics that he uses to grade them, I don't know what else people could want. I got all As on exams with probably 10 hours of studying for each of the midterms and 15 hours for the cumulative final.

Overall, some of these reviews on here are just wild, like I understand people not getting the grade they want, but coming on here and blatantly lying is wild to me. Lannan was great and based off what I have heard, he is one of the better 153A professors. Long story short, if you work hard you can easily get an A, I would take him again in a heartbeat.

In writing this review I find myself conflicted. Ryan has, I think, the ability to lecture well, but his backwards attitude and disrespectful, ego-driven attitude prevents him from doing so. Please don't disregard all the negative reviews thus far and attribute them to spiteful pre-meds who got bad grades. I did well on Ryan's tests but still am able to see very clearly that he did not teach well or facilitate a friendly learning environment this quarter. And from what I heard from past students, this was not an isolated incident.

For some reason the debate on Ryan's abilities as a professor became polarized as the course went on, which is probably why there are so many impassioned reviews with wholly opposite outlooks. I have nothing against Ryan, and am judging him based solely on how well this course was structured/taught.

His tests were graded very harshly, especially when the questions did not lend themselves to such exact answers. He expected punctuality yet was late to classes, uploaded homework/study materials very late, and overall displayed an abhorrent lack of preparation. His leniency for aspects of the class relating to COVID were rigid and unforgiving (all my classes including a lab offered a fully hybrid option except this one).

That isn't to say that he never improved over the quarter. During the last few weeks, he seemed nicer and more understanding. BUT, I have a nagging suspicion that this was because he saw how negatively he was viewed and was hoping for better end-of-quarter reviews. He even gave us a ~5 min spiel during one of our lectures telling us to give him better scores than he deserved so that he could continue teaching (a sign of the times, maybe). So any improvement mentioned in these reviews should be taken with a grain of salt.

Also, he lives near me and lemme tell you, homie walks like a punk.

do not take 153a with Lannan if you can afford to...no matter how much effort I put in I do not do well on his exams and as others have said you get points off for having the right answer (I circled the right aa on MT 1 and didn't get points for it lmao). it's really discouraging to know that your professor doesn't care about any feedback we have or decides to dump extra material on us 2 days before our midterm. what sucks too is that we aren't given any resources or practice questions other than a study guide that doesn't reflect his exams and questions written by the TAs (god bless them). honestly, lannan has the potential to be a great professor, and it's a shame that most of us are struggling so much right now. i personally know several people who have dropped the course because they couldn't take it anymore, so the reviews we're leaving are accurate. don't know how this class can be redeemable at this point imo
