Reviews
Sanchez is an amazing lecturer and is super passionate about math. His lectures are engaging and helpful, and he publishes notes for all students to use. However, Sanchez's exams are EXTREMELY hard. This class is difficult.

Pretty sure almost everyone just studied for a day or two before the exam after learning nothing this semester. even if you go to class, you don’t learn much

Not a lot of homework and a takehome midterm. The class is not too bad to do well on if you do well on the final. the textbook is really good so use that to get an understanding of the concepts.

A great math class, starting to get a bit more theory based but interesting and has enough applications to be relatively easy to understand the theories.

Sanchez is a great lecturer, and makes matrix algebra engaging. At the start of the semester I went to multiple professors and Sanchez definitely has the best teaching philosophy of him Roman and Chi(also the funniest!). Sanchez’ class is not all sunshine and rainbows though. He teaches this subject to learn and tests us on our understanding instead of the students ability to calculate. Fun class and very rewarding.

I know a lot of reviews say Sanchez's tests are hard. I have a hard time believing these people went to class or did the practice exams. His exams are so doable, the questions are just like the ones he asks in class and puts on practice exams. He gives a lot of extra credit, and curves generously. If you have an average understanding of the content, which is pretty simple, you can get close to perfect scores on exams. Im telling you that this class is easy

Sanchez is a pretty good lecture and post his notes (which are very helpful). You will learn a lot in this class, but be prepared to get a bad grade.

Class was not great - he talks very fast and is hard to undertand plus doesn't look up. But he is really nice in office hours, midterm is online, and homework load isn't bad. I learned everything from textbook and tutor

Sanchez gives extremely difficult exams compared to the other professors. He is funny and a great lecturer though. Exams are hardly computational and mostly involve complex logic / proof style problems even though he refuses to call them proofs.

Midterm is online and I think we had like 4 total homework assignments so isn't too bad. That being said the professor is awful - he doesn't look up while teaching and is bad at explaining the concepts. Our class was completely computational and I know others were completely theoretical, so it matters which professor you take it with.

Hard to understand if youve never dealt with matrices before. Requires alot of practice.

Take home midterm and most of the class had the instructor manual with homework answers. Final is kinda tough since 20 questions multiple choice in person but if you can find an old version of the final and drill those concepts using the book as a supplement you will probably get an A

You definitely learn a lot. Sanchez makes the tests extremely difficult. He also teaches to only a couple people that know a lot during lectures. His office hours were helpful though. Getting a great grade is tough, but it will really test your problem solving skills

you'd think it's his first time teaching the class bc he has no outline of the content anywhere, doesn't use online tools (besides canvas) for anything, rambles at the board, and makes tons of mistakes. you'll end up having to teach yourself everything at the end of the semester for the final, but you probably won't know what to study

He is a very poor lecturer. However, he has ~4 homework assignments, a take-home midterm and an in person final with a 5x8 (front & back) cheat sheet. You will likely have to teach yourself the content and how much time you spend studying for the final exam will likely determine your final grade. He is more helpful during OH than in class.

Chi is a really nice guy and gives a pretty decent lecture on matrix algebra. The course is just designed incredibly poorly where students are graded on 5 homeworks before taking a final worth 35% of their grade. Makes most of the semester very easy, but you have to learn an entire semester of matrix during reading week to do well.

Amazing professor but hood tests are really hard. You have to really work for a good great but soo worth it

Sanchez is an incredible lecturer, very organized, prepared, high-energy. One of my favorite classes, and I don't say that about every math course. Tests are hard but the practice exams are incredibly relevant and worthwhile. Going to office hours regularly throughout the semester was the best decision I made in terms of understanding the content.

Lectures were very bad, he constantly makes mathematical mistakes. The take home midterm and homework are very easy. For the final, since I didn't go to class and just studied for a day, the grade is what I expected.
