THE RELIEF after finishing this class. You will have no life when you take this class, wait until winter / spring for a better professor! She expects you to rememberize a whole biochem textbook, which is expected of a UCLA biochem class, but there must be easier professors out there who just give out A's like candy. I dont really appreciate her condescending attitude though.

She's a bitch. No feelings or whatnot. You get so annoyed of her squeaky voice.

WAY TOO MUCH MEMORIZATION! She overloads you on information and expects you to regurgitate it out every 4 weeks. She's too busy in her Office hours and does not reply to email.

I'm really not getting the negative reviews here!

I personally really liked Tienson. Sure, the woman could have used a few more outfits throughout the quarter - she was particularly attached to a dark blue knit sweater when I took hear a few quarters ago. But jokes aside, she was overall a solid professor. She has the no frills approach, which means she won't sugar coat things for you. She will lay things out for you as they are, and will expect you to do learn them.

However, she does guide you along.

I must disagree with a number of posts that say that the study questions didn't help. Honestly, that's all I did. I stayed on top and made sure I completed those long, tedious study questions every week. That's what helped me get a solid grade in the class, to be honest. The study questions. DO THE STUDY QUESTIONS. I cannot emphasize that enough. Her tests are very similar to the questions. Sure, she may throw in a few twists and turns in her questions, but if you did the study questions, then you have enough practice to recognize any twists and turns she may have on her tests.

Her exams were overall fair. Her final was a bit harder from what I remember. I don't think pure memorization would do you well in the class at all. I completely disagree with the posts that simply say to memorize everything. A lot of the topics in this class are pretty conceptual.

Tienson may not be the nicest professor but she gets the job done. Her lectures aren't super fun or exciting, but to me the material was interesting enough to keep me focused. Her lecturing style is a bit dry (don't expect any jokes to keep you alert), so make sure to pump yourself with loads of caffeine before coming in to keep you awake. However, I honestly think she means well. I asked her for a recommendation letter a few quarters after taking her class, and she was more than happy to write it. She's not a bad person. I just don't think she knows how she comes off as sometimes.

Take her! I've heard the other biochem professors are worse. All the best.

Tienson is one of the best professors I've had at UCLA. I'm not a biochemistry major and was very nervous about taking the class. However, she does a great job of simplifying difficult concepts, is an engaging lecturer and gives fair exams. She prepares you well with tons of study questions and review sessions. Her exams are always based off what she lectures from and if you work hard you can get a good grade in her class. Also she is incredibly nice if you ever go to her office hours. She's really dedicated to ensuring all her students do well in her class. I highly recommend her if you're taking 153A! As long as you stay on top of lectures then you'll do well in the class!

Great Professor. She really cares about her students' success in her class. I would recommend her for chem 153a compare to any other professor. I'm selling the book with the folder for only $65. This book is only for chem 153A, so if you are planning to take the other biochem series, u should get the complete edition. message me if interested: jtan885@gmail.com

I worked my ass off and tried Addy for the first time because of this class. It definitely paid off, but I would have preferred another professor. I found Tienson impersonal and struggled to keep up with the material. I spent the entire quarter catching up on the material. I found my TA (Kyung) very helpful, however, and it helps to review LS2/14A-D beforehand.

There were 10 extra credit points for just giving her feedback and survey.
Do the study questions and understand them. She is a very nice professor and a bruin for like 10 years. Go Bruins!

So many people have told me to avoid Tienson but she's usually the only professor teaching 153A. I actually enjoyed her class a lot. The material isn't that difficult. It's a lot of what we've already learned from LS and the Chem series but more in depth. As long as you go over all her slides and study questions, you'll do fine in the class.

Her curve is very generous. I struggled in a lot of my lower divs but still got an A in 153A (meaning it's definitely possible to do well if you don't slack off). The discussion forum was also really helpful, since Tienson is always active on that. Overall, I really liked her :)

I understand why a lot of people don't like Tienson because her class is definitely tough. You have to keep up with the materials every day since she expects you to not only understand the facts, but also know how to integrate them in the exams. This course includes the basic foundations of biochemistry, so it contains great amount of information. However, I like her teaching because she is very clear in explaining concepts and in what she wants you to know. If you go to her office hours often and master the study guides before exams, you will get an A for sure. Personally, I think Tienson has a generous curve at the end and her final is really tough, so don't slack off even when you get good grades for midterms.
