Quarter Taken: Spring 2017 Submitted June 28, 2017 Grade Received: A

This class was definitely an interesting experience. Personally I think that the way I handled it was poor, so this review is also going to be a reflection of what I could have done to avoid the stress/panic that hit me two days before the final exam.

The first midterm was relatively easy and similar to the practice exam she posted, with an average of 80. I studied a decent amount and got a 93. The second midterm was a bit harder, with an average of 66. I half-ass studied because I was having a really bad week and sort of just winged it, and got an 82. This is what screwed me over before the final. I let my guard down and started half-assing everything after the second midterm (also because the material was dense and boring as hell).

So don't do that. Even if you do well on the midterms, just know that the final is much, much harder. I ended up getting a 144/200 and an A in the class, but it was too clutch for me to feel comfortable with myself. Make sure you stay on top of the material no matter how boring or dense it is.

Tienson posts really helpful study questions that give you a good idea of what her test questions will be like. They are repetitive, but helpful. When doing the study questions, pay attention to the little details that she mentions over and over--most likely, if you don't mention them on the exam, she will dock off points since she grades using a (somewhat) strict rubric.

As a teacher, Tienson was okay to me, personally. I complained a lot about her going too quickly in class, but honestly that's what BruinCast was for. During week 10 I rewatched one lecture and realized that I should have been rewatching most of them throughout the year. Watching BruinCast REALLY helps because it really helps you synthesize the material and pick up little details that you may have missed during class. As a person, I don't really know how she is but she seems nice. I didn't have many chances to interact with her.

Quizzes, homework, and clickers are easy points so try not to miss any. Do all the extra credit because it adds up (it saved my ass). You will need all the points you can get because it'll act as buffer for when you take the final. To be honest though, with all the easy/extra points she gives and her extremely generous curve, an A is completely manageable, especially if you try your best in the class.

Overall, I didn't like this class very much, but it's because I didn't enjoy the material--there were a few concepts I found really interesting, but for the most part it was meh. Personally this class was more or less chill throughout the quarter, but stressful as hell every time an exam was around the corner. But that's because I slacked. So if you don't slack and earnestly work for an A, you should be fine. Tienson seems like the type who wants to help her students succeed, I don't think she's out to get anyone.

The Good:
1) many opportunities for extra credit
2) provides study questions that will help you understand material
3) does a decent job of explaining material

The Bad:
1) tests are more about how she taught than what you learned
2) heavy reliance on study questions is necessary
3) discussions are a waste of time

Tips to Get an A:
1) do the study questions SLOWLY and without looking at the answer key; ALWAYS understand your mistakes
2) flashcards are necessary for all the structures; pathways can be memorized if you review every other day
3) read ahead by skimming; look at headings and pictures before coming to class
4) take sparse notes during lecture; review and update notes by rewatching/listening to podcasts
5) stay half a week ahead with her study questions no matter what; it will pile up so you have to stay ahead

I will start off by saying that Dr. T is one of the best professors I have ever had at UCLA! Pls do not be scared of this class, it is very possible to do extremely well. i will admit that 153A was challenging af, but Dr. T made it enjoyable in the process. some tips for success:

1) get all points possible for perusall (reading assignments) and those 5 in class quizzes (honestly, it's just memorization so there's no excuse not to get full points)
2) midterm 1 average was around an 80, midterm 2 was around 66 (be sure to do above average, def possible if you really practice all her STUDY QUESTIONS and practice midterms
3) do the STUDY QUESTIONS (she uses concepts from the SQ for her midterm questions)
4) utilize all the Learning Assistant resources (go to the problem solving session and weekly concept reviews)
5) watch the BRUINCAST bcuz Dr. T can kinda go rather fast in lecture (most of the answers from the study questions are practically said in lecture)
6) STAY ON TOP OF THE CLASS (i know this kinda obvs but the more u study from the start, the more it will pay off trust me i started studying for the first midterm week 1 by staying on top of the study questions and going to the LA problem solving sessions... i ended up getting an 88 on midterm 1)
7) Beware of the final exam.....it is definitely the hardest part of this class, spring 2017 final was def a lot diff from her midterm style just try ur best on it (i got a 136/200 and still ended up with an A in the class)

Enjoy the class and Dr. T she's amazing and her curve is very generous (like seriously generous) Good luck with class...you are in good hands with Dr. T

This class isn't too bad so don't be intimidated to take it. Personally, I was really worried I wouldn't do very well, but I ended up with B+. The hardest part is the amount of information we are required to learn. There are four quizzes which are actually helpful in that they force you to learn things that are vital to the tests like amino acid names and structures. She does offer extra credit, clicker points, and reading points, I recommend trying your hardest to get 100% in those areas since it will end up being a big grade booster, but don't spend too much time on the readings since they don't help very much with preparing for tests/quizzes. Overall, it is an okay class that is required for some majors to graduate so just study hard and do the work and you should be fine.

Quarter Taken: Spring 2017 Submitted June 27, 2017 Grade Received: B

Nothing could have prepared me for the final for this class. The average was a 62%. It's all fun and games up until the final.

The first half of the class is very manageable and easily understandable without putting in too much effort. After the first midterm, the material does tend to get more complex and detailed, so make sure you persistently put in the work and effort needed to obtain your desired grade. Tienson has an amazing curve for Biochem153A, making a 84 and above an A grade for the class. She teaches you everything you need to know for her exams and prepares you relatively well for the tests. Some of the questions on her exams are not directly from her notes, but this is because she wants her students to apply what they have learned in lecture to the test questions. She recently incorporated Perusall to her teaching system, but it was not very helpful to my overall understanding of biochemistry; just make sure you skim the readings and post a few comments to get max points (it is really not that hard to do this!). The protein assignment does get a little tedious, but work on it with a few classmates, and it won't be as bad as you thought it would be!
Tienson does offer a few extra credit points here and there, and although they may not seem like much (sometimes they are worth 1 point), make sure you do them because they DO add up and may help your grade!
Overall, Tienson really cares for her students and has a very admirable passion for biochem! All the knowledge she retains and regurgitates never fails to amaze me in class haha. Yes, I had to put in a lot of work and time into this class to yield good results, but it is definitely not impossible. Biochem153A was NOT the hardest class I have taken at UCLA; it was actually pretty fun and enjoyable compared to my experience with the lower division chem classes.

This class is a lot of work, but it's rewarding. The workload is ass. Thankfully, Dr. Tienson is a very good professor, and she's also nice. 10/10 would recommend.

Quarter Taken: Winter 2016 Submitted Feb. 12, 2017 Grade Received: A

I really think this class is not that bad as a lot of people make it out to be. Take a look at the grade distribution. 30% almost getting As is pretty high.

Anyways I would say I learned quite a bit in this class. Like others are saying do all the practice problems and you will be fine. Going to discussion also helps and the forum on CCLE helps to clear up any questions you have. If you are interested in biochemistry that definitely helps

Quarter Taken: Fall 2016 Submitted Feb. 3, 2017 Grade Received: A

Dr. Tienson is actually a good professor. Do the study questions and do her past midterms then you will get an A.
