As others have pointed out, this class requires you to memorize everything you can imagine and more. If you struggle with endless memorization like I do, then avoid this class at all costs. You will be in for a lot of pain, like I was. If you are good with loads of memorization then you should be just fine. Others have called her cruel, but I disagree, this class for some, like me, is impossible.

Tienson is one of those professors who tell you what they want on exams. If you can memorize the answer keys to her weekly study guides word for word and transcribe them onto paper, you are set! Since she is new as a lecturer, she really tries her best to maximize what her students can get (generous grading curves, recycled test questions, Bruincast). Do what you need to do and you are good. Focus on her slides and mostly her study questions. Draw out the whole metabolic pathway using colored pens! iClickers are required for points! The class curves were relatively high, so it'll probably be only a matter of time before she changes up the structure of her course, which she's retained for the 5+ quarters she's taught at UCLA.

She was an amazing professor. Her lectures are very structured. Do the study question and start doing them right away because they are a lot. They resemble the questions in the exam.

Another user posted that she doesn't reply to email. She tells you at the beginning of class that she won't reply via email to content questions, but will instead have you post your question on the online discussion forum and will answer it there. That way, everyone has access to the information. She's excellent at replying on the forum, especially to questions about the study questions.

She seems to be the only one teaching this class, with weiss teaching it on occasion. Weiss is said to be even worse. So unfortunately, just take it. 153A is loads of memorization regardless of who you take it with.

a new professor at UCLA for biochem. She's awesome. organized lectures and study guides. the exams are pretty much based on the study guides. memorize them!!! 5 quizzes - easy! everything you need to know for the quiz are given beforehand. 2 midterms, 1 final - cumulative. OH helped a lot! and discussions and forums too. I highly recommend her.

She is a really hard and challenging professor. Curves hard (average set at B-/C+) and expects you to regurgitate approximately 600+ hardcore slides by the end of the quarter. Would recommend waiting and taking with a different professor. She has gotten harder over the past quarters due to complaints that her class was too easy. Unapproachable in OH and has no interest in your wellbeing (she teaches approximately 800 students a quarter).

The fundamentals of Biochemistry isn't that complicated, but she makes it so. If you're into straight memorizing and regurgitating, then this class is for you. But if you're into concepts and logical reasoning, then look elsewhere. No point in reading the book because she uses multiple texts. Just memorize her studyguide answers verbatim. Office hours is painful. She doesn't like to go into deeper concepts and disregards any further curiosity on the subject matter. She just wants you to learn whatever is on her studyguide.

Tienson is really fast when she talks, but I managed myself to get an A. (got above average for the 1st midterm, and did really well on the second midterm and the final). Just memorize everything she tells you to memorize, and look at the studyguide she gives you carefully. MEMORIZE EVERYTHING and you will be fine.

Good Professor but very hard. She purposely makes the exam hard and her study questions doesn't really help at all. I disagree with her grading as your answer have to be matched with her keywords from answer keys. After i view my exam solution keys, I don't even know or derive her key words in solution keys. You won't get any partial credit if you don't match her keywords and that sucks. The TAs for this class are stupid. They do not come to her lecture and hardly anyone know anything. Just be prepare when you take her. Not an easy exam I would say. The material itself is interesting and doable so is her quiz but definitely not her exam. Her exam was a BOMB
