DON'T BE AFRAID TO TAKE THIS CLASS!!! Everyone always talks about this class like its the most terrible thing ever! Yes, the reports are actually 20 pages long but there are only 4 of them in the quarter and one of them is a group written report. Literally the only knowledge you need is from BIPN 100. After you take BIPN 100 take this class!!!!!!!!

Catalina is one of the most amazing professors at UCSD! She's extremely personable & approachable, and great at explaining concepts. She's adorable and she tells funny stories as well! Take BIPN 106 (comparative physio) with her too if you can. She loves animals (she brings her dog to lecture) and you can tell she's very passionate about her work.

Wonderful woman and interesting topic. However, the grading system is extremely unforgiving. There are essentially three exams of equal value in points, so doing poorly on one will make it impossible to succeed in the class. She asks about every single detail she lectures on, so it is extremely difficult to study for. Vague grading system. :(

Pay attention in lecture, attend discussion, and re-listen to podcasts should get you a good grade! She is extremely friendly; she also brings her dog to class.

She's extremely caring, she pauses to ensure people understand, she decorates her lectures with relevant experience which makes things easier to listen and relate to. She's available for office hours and really ensures you understand concepts rather than forcing brute mem.

She is a great prof. But her accent is strong, I'm having a hard time to understand what she is talking about even with 0.8x on podcast. Her first exam is extremely hard and mostly focus on week 1 and 2. Most of the class didn't finish the exam on time. She teaches too much details and the slides only have pictures, no explanation.

With professor Catalina it's not about memorization, but rather truly understanding what's going on. Her exams are for the most part application based, and all free response. Her midterms weren't that difficult, but her final was extremely challenging. She crammed 2 chapters before finals week, which we were expected to master in a weekend.

Not a great professor, lecture material was essentially the textbook skimmed down and repackaged. She cant even come up with her own metaphors and just uses the ones in the book. The good thing is youll do better than your peers by relying on the book (25 bucks on amazon for the paperback) than her lectures.

One of the most challenging, yet rewarding classes I've taken at UCSD. The experiments and dissections aren't too bad, but the lab reports are a challenge. 20 pages each, and very in depth. Make sure to attend lecture. Utilize TAs and Catalina. Catalina is super sweet and will answer all your questions. Generous curve as well. Study hard for final.

Nice lady for the most part, but many of her exam questions are poorly-written so unless it's a yes/ no/ circle question, don't be concise-- write more than you think you need to answer the questions to increase your chances of hitting the exact keywords that she is looking for.

BIPN classes are always going to be difficult bc there's a lot of information however, Catalina is a great lecturer and is understanding. As long as you do the bare minimum of note taking + doing assignments, there's no way you will fail the class. The exams seem difficult but it's all based on what she teaches in lectures + ur critical thinking.

She is super knowledgeable on human phys and it shows in her BILD lectures. She does a great job breaking down complicated concepts and provides very fair study guides for exams. I'd recommend sitting in the first few rows, she'll chat with you about random stuff and she's very kind and funny.

Professor Catalina is great! She is a very clear lecturer and tries her best to teach in a way that students can understand. She gives very clear study guides for the exams and her grade is curved! She is very sweet and is happy to answer any questions on confusion. Code is needed for participation.

Caring professor. However, the lecture slides are narrow with only photos and her strong accent made it even harder to understand. There was little work to do in this class, so your grade depends on the 3 exams. The exams weren't difficult though since we had an extra hour to complete it.

Catalina is a great professor! BIPN 100 is a bit dense in itself, but she does a great job of covering the material and the grades are extremely fair based upon the material we learn. If you put in decent work and study the class notes, do the problem sets, and finish the HW on time you will excel under her mentorship. Great class, great professor.

Some people love her because she's funny and genuinely cares about her students; other people find her lectures unhelpful, dense, and unorganized. I understand both sentiments: if you care to seek out help, you'll learn a lot, but her lectures are not the best; she describes and tells without explaining much at all. Wonderful person, eh Prof.

She genuinely makes you work for your grade, this class took not even joking 20+ hours of studying a week, for me at least. The TA's are very specific graders, so make sure to read know the basics of almost every topic(50/50 free response and multiple choice. Physio is dense but Catalina tried her best since she seems pretty passionate about it.

Midterms are difficult even if you study a lot. Lots of hypothetical questions. Study guide/ problem sets do not help prep you for exam. Must study every detail from lecture.

I really like her as a person, but not so much as a teacher. Her lectures are very fast-paced and are also confusing, because she teaches at a BIPN 100 level. A lot of the tests are hard to do well on, especially when you study for a long time. She does not provide a practice test so it is very hard to understand, and a lot of hypotheticals

Overall this class is one of the harder bio lower div classes, but she makes the process of learning all this material so much more complicated. The accent she has is not bad as other reviews say it is, but rather the speed at which she goes through content. Also the tests are hard and grading is unclear as the average on midterm 2 was a D.

Honestly she was good at lecturing and went over things in great detail. She answered any questions students had in class and she emphasized what she wanted us to know. However, exams were tough. They were application based meaning you had to understand the material, not just know it. Midterms were outside of class time and attendance was mandatory

A lot of people were complaining, but I really liked her class. I came in super worried! For a lower division biology class, it is challenging, but it prepares you for upper div bio (she made me interested in physio). As long as you go to lectures, you will succeed! I would rewrite notes from the podcasts and try to understand the concepts
