He is very helpful, perhaps too helpful. He really spend a lot of time to explain stuffs that people don't really understand, but that makes the class a bit too slow. However, I guess pchem for biochem students isn't really a tough course, so he's probably a fairly reasonable professor.

Professor Sepunaru has to be one of the best professors I've had so far. His lectures are engaging and really makes you think about the real life implications of the stuff you learn. He is extremely encouraging and is there to help you succeed. Go to office hours and don't be afraid to ask questions.

Three words: For The Students. Dr. Sepunaru is my favorite professor at UCSB and for good reason, his lectures are interactive and make you think about real biological applications of the course content. As a biochemistry major in the MCDB department, I'm sad that I can't take more classes with him at the helm. Take this class with him if you can!

Lior is one of the best professors I've had so far as a junior at UCSB. He takes his time in lecture to make sure everyone understands. His office hours are very interesting and helpful as well. I would totally recommend having him as a professor.

Dr. Sepunaru is one of the most down to earth professors in this department. Unlike some of the professors in this department who will laugh in your face for asking dumb questions or rush through material without explanation, he really teaches for your understanding. Pchem is still difficult, but the vibes of his classes are phenomenal.

100% my favorite professor at UCSB. He so easily grabbed my attention every lecture. I loved how he makes a lecture feel like a small discussion section by asking many questions. All of his assessments were reasonably fair and graded very easily. Everything was communicated very clearly and overall, he made this class a good experience.

Prof. Sepunaru's honor class was probably trying to cover a semester worth of topic in a month and expecting student to have in-depth understanding in contrast to regular chemistry elsewhere. He did amazing lectures, but if you skipped reading then the lecture will be very demanding. Grading was very generous, like I don't feel I deserve the grade

Overall, Professor Sepunaru was a good lecturer. Homework was very time-consuming and required you to read the textbook and do some research. Go to his office hours because they provide helpful details about homework and exams. However, his homework and lectures don't prepare you enough for the exam so make sure you digest the topics thoroughly.

Professor Sepunaru was a great lecturer. Each lecture was structured to maximize engagement and often consisted of topics that were both important and interesting. He was easy to reach outside of class and regularly hosted office hours, which were almost like extra lecture sessions each week. Exams were difficult, but they inspired people to think!

One of the best chemistry professors I have experienced. I enjoyed the straightforward communication when any confusion occurred. Also, the lecture is fluent in that it depends on the students' struggles. Although this had some downsides (not able to cover the entire topic), valuing the students' understanding of the concepts was great.

Simply the best professor I had. His lectures and exams are intellectually demanding and he expected you to have a much deeper understanding of the concept compared to Chem 1B. Much emphasis is put on mathematical proof and if you have poor background in calculus (like me) you will suffer. However it still worth the price because he is amazing

One of the best educators I have had! If you have a genuine interest in the material you will succeed. Although content is inherently tough, as he pulls heavily from physical chemistry topics, the applications in exams are doable if you truly understand the material conceptually. Go to office hours! He is very accessible and friendly.

Liron is great at having a great vibe every time and maintains the interest and engagement level high. It is a pleasure being his student

If you like chem and are willing to put in the time, you'll LOVE Sepunaru. He's an awesome guy, really cares about every one of his students as well as the subject. But his tests are very very difficult so just make sure you know what you're getting into!

Not the professor for everyone. As an soft science major, I just wanted to get past chemistry. This prof. places an emphasis on depth and understanding. There were 4 free response questions on the exam that seemed somewhat like AP FRQ's. Overall very kind and wants you to succeed but probably wouldn't take again.

Really great professor! He wants you to love chemistry. If you don't understand what he talked about in class, go to office hours, he will explain as many times as needed. His tests and final were definitely fairer than other professors. Don't miss lecture, since he goes away from the book at certain points. Offers extra credit (did not do it tho).

He might not be everyone's cup of tea. He places greater emphasis on understanding the material thoroughly than high grades. Tests are unpredictable due to the nature of his questions (teaches out of book commonly), but understanding lecture material is the best study method. One of the hardest classes, but rewarding to learn Chem from his lens.

His lectures are unrelated to the test and hard to understand

Professor Sepunaru was a good professor, but not-so-great if you are taking him for gen chem as just a prerequisite for your major. In order to succeed in this class, it is extremely important that you attend his office hours and study material outside the textbook, due to him constantly teaching/testing on material from outside sources.

If you're taking this class just for a pre-major req, then this professor is not for you. He delves into the topics more deeply than other gen chem profs, but if you go to his office hours, he breaks down the topics well. Also, his free response tests are hit or miss, but partial credit is godsend! Go to office hours and review lecture problems.

I love Professor Sepunaru. I do question whether he is the right professor for a gen chem class that requires regurgitation of chemistry subjects to students who the majority do not want to have anything to do with chemistry. He is super caring and nice, thinks about what would be best for his students a lot. Wants people to understand the material

Caring, knowledgeable, passionate, and too smart to be teaching Chem 1B. Exams were very concept-based and basically all free response, and while he was very generous with grading, studying around the clock wasn't enough to prepare for whatever curveball was coming on the exam. Great for some people, but not if you're just trying to pass the class.

Sepunaru loves the subject and has an amazing attitude towards teaching. He really wants to be a mentor to his students, and to inspire them by showing them connections in the material that go beyond the standard curriculum. Lectures can be a bit disorganized and off the cuff, and tests are free response (not for everyone), but a great experience.

Professor Sepunaru is an amazing professor. He is very accessible outside of class if you send him an email. His tests are hard but very manageable if you read the textbook before his lectures. Ask questions in class and keep up with what he is saying and he makes Chem 1B very interesting.
