Comment: Pachter was kind of disorganized. We were supposed to get homework every week but that didn't happen and his lectures were sometimes difficult to understand. I think having a good GSI really helped me for this class.

Comment: NO. Don't do it. If you're coming in as MCB/pre-med like I did, JUST TAKE A DIFFERENT MATH WHILE YOU HAVE THE CHANCE. It's going to become an actual pre-req for MCB pretty soon. I would have definitely taken Math 1A if I had known what this course was like. I came in with an AP Stats and AP Calc background, but it wasn't enough. He'll literally teach 2 lectures of calc, then a lecture on stats, then a week of Taylor series and the week after, probability. If that's you're thing and you have a strong background in both, then by all means go for it because it is a VERY useful class for MCB/premed students. This class isn't meant for everyone (obviously me included) so take my advice however you'd like. There's no textbook for the class so it makes it hard to work on extra problems if you want to improve, since the problem sets really aren't enough to prepare you for the quizzes and midterm. Last piece of advice: Get a good GSI. Your GSI will make or break you because Prof. Pachter, though very knowledgeable and enthusiastic, is all over the place. Lovely man but I wish he would've taught the class differently so that it made sense.

Comment: I entered this class having taken Calc BC and AP Stats in high school so I had previous exposure to 60-70% of the material. In the end I managed to earn an A+ in the course. First off, the cons about this class: 1. We DID NOT get enough homework problems. 3-6 problems a week is definitely not enough practice, especially for those first-time calc/stats students. I did not take the adjunct but there were mixed responses from my classmates who took it ranging from very useful to useless. 2. We did not cover topics in detail. In fact, I felt that AP Calc covered certain concepts in more depth than this course did. 3. The structure of the class felt somewhat disorganized. For example, we covered Integrals before derivatives and then Taylor Series immediately afterwards in the third week. Pros: 1. If you did well in AP Calc and Stats in high school, then this class won't be too difficult. 2. We got to learn some super cool concepts that typical freshmen have never seen (Poisson's distr, max likelihood, etc.). Even though we didn't cover many topics in depth, we did cover a multitude of concepts and learned some practical mathematical applications. 3. The lecture slides he posted online were extremely useful and made up for the lack of a textbook. Since we didn't have enough practice problems, I made sure to carefully read the lecture slides. The two midterms were rather straightforward, which can be a bad thing since the class is curved. However, the final exam tested how much you understood the material and was very fair. The quizzes were of moderate difficulty and contained questions that were harder than some of the exam questions.

Comment: The problem with this class is that it's sooooo unorganized. Originally, we were supposed to have problem sets due every Monday and Friday, but then for some reason, mid-semester, there was no longer any hw assigned for at least two weeks. Then, homework was assigned pretty much once a week, but sometimes not at all. It kind of made the course less legitimate than it already was. Anyways, Pachter definitely is not the best lecturer, but boy did he improve over the semester. I remember in the beginning of the semester I slept through pretty much all his lectures, but as the semester went on, I became a lot more invested in the class as he became more of an interesting lecturer. The midterms and final for this class were VERY decent as well. I had the most horrible GSI, which made going to discussion a waste of time, but I still managed to pull off a very good grade. If you have little background in calculus however, I would recommend taking the SLC's adjunct course.

Comment: No, just no. From his quizzes, to his homework to his exams, everything EVERYTHING was horrible. Nothing helped me prepare for the butthurt that was the final exam and midterms. Definitely try to get an awesome GSI that will help explain everything to you.

Comment: Really awesome professor. He is really passionate with math and you can tell he is really smart. His tests were really easy as long as you study you will be fine. He is really helpful outside of class as well(what I heard, never actually went). He taught some useful things that you ca actually remember in real word. I really like him as a professor. Just one question is he did not really teach much since he was doing his research so he was not fully engaged in lectures.

Comment: I had him for Linear Algebra + Diff EQ. His lectures were very disorganized in my opinion, and he went off topic often in lecture. Then, halfway through the semester, he realized he was behind, so he began to rush. We barely covered PDE and fourier series, and overall, I just didn't have a very good learning experience. At the end of the class, his grade distribution seemed completely random, as students with high test scores got poor grades while some students with lower test scores got better grades, and a lot of students complained. He was quite unresponsive, but in the end he realized he had made a mistake calculating grades and then fixed the mistake. I feel like he was not very responsible as a professor, and if I could go back, I would not have taken his class. The tests are ridiculously easy, almost like a joke, which can be good if you're careful (you'll get 90%+) but bad if you make one careless error as there are only 4 questions and it can completely destroy your grade. There was little curve in this class, so hopefully your raw score was high.

Comment: If you want to understand how to do any of the problems on the homework, midterms, or final, you will need to read the book, and I mean actually read all the assigned sections. I went to all of his lectures, but they were absolutely useless. He sometimes covers abstract applications that have no relevance to what he will test you on. He is one of those professors that is so wrapped up in his intelligence that he doesn't understand we are just starting to grasp the concepts. His big saving grace were the exams. There were very reasonable (read: easy). He wanted to make sure we understood the basics, so he wouldn't ask us the hardest possible problems from each concept (not even close to that). I am not one of those students who easily understands math. I lived in my GSI's office hours, and I did god knows how many practice problems. Therefore, believe me when I say his exams were very nice. In summary, you'll hate Pachter in lecture but love him during a test.

Comment: My all time favorite Math professor. The lectures gave a good background for the homework, although it didn't really teach you how to do the problems. The exams were very fair. He asked simple questions, that were not beyond the scope of our knowledge. Perfect professor. Very enthusiastic.

Comment: Enthusiastic about teaching this new course. His assignments are fair for the most part, they just require a good amount of time sometimes. Midterms are fair but finals are usually harder. He is available and willing to help but sometimes he can lead you on the wrong path for some things. He'll explain something and say this is the general manner but then the answers to the homework reflect the opposite.

Comment: Makes things 10x more complicated than they really are. His homework can be found word for word off the internet but sometimes he makes ridiculously hard questions out of the blue. His exams are easy for those who have taken AP Calc and Stats in HS but rarely has anything to do with the material in class

Comment: Pachter is one of my favorite professors. He clearly knows the materials he's teaching in class (though sometimes the explanation isn't exactly lucid) and he has a lot of enthusiasm too. The materials taught in this class are very interesting and applicable and are fun to learn as well. However, this is a statistic loaded course so it'd be even better if those who want to take it touch up on some statistics before taking this class.

Comment: Pachter is definitely one of the better math profs. His explanations are pretty clear and straightforward and he's relatively interesting to listen to. His homework assignments, while short for a math class (around 10 problems/week), can be challenging sometimes. He's very passionate about what he teaches and he's usually friendly when you ask for help in OH. Exams *generally* reflect what we've learned/homework assignments and are medium in difficulty. It sucks to not have an actual textbook for this class though! I suggest (for the combinatorics part of this course at least) getting/borrowing a Math 55 book and referring to the relevant chapters. It is very, very helpful.

Comment: The teacher is great and you can tell that he really loves what he does. However, the class is a pilot class and doesn't have a book or any form of support besides the SLC, which does problems for our class differently than our professor and gets them wrong.

Comment: Take this class. It has been the most interesting and useful course I've taken at Berkeley so far. This class will also be IB/MCB-required in the next two years. Pachter is an awesome professor! He's actually in the process of writing the textbook for this course right now. He is extremely passionate about his teaching and about his students' well-being. I still remember when he brought ice cream sandwiches for the whole class! Great class, great professor.

Comment: The homework is rather difficult, and the exams are hard if you don't get the material very thoroughly. The professor is very nice and amicable, but the notation does get very confusing, and it is a very fast-paced class. It is in a experimental phase, so I think the professor is still fiddling around with the material and trying to get it just right. In that sense, the material is harder than I would've expected out of a bio-math course. There is no textbook for it; you have to find reference material yourself. If you don't have a good background in calc and stats, this class will be horribly difficult for you, as it as been for me.

Comment: This was the first semester that this class was offered and all I can say is that I am enjoying it. The topics are interesting and you move at a fast pace and a good background in Stats, Calc and Bio can really help you out. I understood the bio examples and the Calculus was easy because I took a lot of Calc in HS but the Stats was hard because I had never taken it before. The notation can be confusing at times too. There is a disconnect between the GSI, professor and SLC. The SLC sucks btw this semester when it comes to the review sessions. But aside from that, the class is great and I love it. But remember it's a 2 semester commitment!

Comment: He's a really cool guy and he knows what he's doing. He'll clarify things for you if necessary. Course isn't terribly easy but that's because it covers a lot of conceptual ground at a quick pace. Homeworks are manageable if you work with friends and the exams are fairly straightforward and representative of the material that was covered. It IS in experimental course.

Comment: Pachter is pretty nice. His explanations are okay, not the best but he definitely tries to clarify things when asked. He tries to make lectures interesting- he even brought us ice cream sandwiches once! BUT, his homework assignments are hard. This was a math class specifically for BIO majors, yet a lot of the homework problems required proofs and were better suited to math majors (even our GSI admitted that he didn't think some of the problems were appropriate). I found that since Pachter wasn't that great at explaining things that it was best to rely on my GSI- Amit- who I think was a better teacher.

Comment: Lior is a good instructor. This semester, the class was on general principles for producing mathematical models applied to biology. We covered some linear algebra, phylogenetics, infectious disease models, and population models. The problem sets were well designed; however, the midterm was very easy, and grades seemed to be assigned a bit randomly. Disorganization is a problem in this class, and Lior stopped giving lectures after the midterm.
