He is a breath of fresh air compared to the other professors I've had at SMC. He provides extra credit opportunities on the exams, but he does not drop your lowest exam score.

Handouts for every lecture, which saves a lot of writing. Knows his stuff. He is also helpful during office hours. 4 short exams, one final project, and a final exam. Homework and project help a lot! Make sure you participate during class. Very good choice.

As soon as you add Professor Flores to your class schedule, boss music begins to play in the background. This guy will KO you on the first exam, then flying roundhouse kick you on the second. He is like the Lvl.9 CPU in super smash bros. The most important thing is to never give up, and when things get tough, tell yourself: "Eigen-do it!"

This Linear Algebra class was BY FAR the toughest math class I've ever taken, but I learned a lot. I finally have a better understanding of vectors, dimensions, and mathematical proofs. This class gave me a new perspective on mathematics.

I have had the honor of taking 13 class at SMC all instructors have ranged from good to exceptional professors with exception of Prof. William. Prof. William created an atmosphere of negativity and fear in the class, I was scared to risk asking him a question. I dropped the class and will be taking it again next semester.

Prof Pachas-Flores runs an extremely strict class He will kick anyone out who is on their phone doodling or if he thinks you aren't paying full attention. He teaches one way of solving problems in class, uses a different way for the online homework & gives tests that combine both but only accepts one very specific answer Gets upset for asking ?s

I never thought I would pass this class. Definitely take him for online classes if he is available because you can always look back at his recordings if you missed something in class. He does take attendance everyday! Also he gives out participation points.. always participate when he asks questions. even if you are wrong. good luck!!

Dont take him for online classes at all. In maths everyone gets a similar answer, but in his class if two or more people get similar answers then he blames you for copying and gives a zero without even listening your side of the story . Would never recommend him.

Dr. Pachas-Flores was the best statistics teacher I could have hoped for. Math has never been easy for me, but he explained it clearly and really worked with me during office hours. He wants his students to do well. He is very organized and grades fairly. Use his office hours office often as it makes a big difference. Highly recommend!!

I do not recommend. The subject itself I did not find difficult and yet in his class it felt the worst. He creates a completely unsupportive environment for the students, it is like he is there to ?lecture? rather than teach and would rather nobody to ask any questions. After 3 years at SMC this is the worst professor I have taken

Do not take this professor. He is friendly and his lectures aren't bad but he grades the tests very hard. He will take a point off for every single minor mistake. If you want an A, take any other professor. I went to office hours, studied, did tutoring, went to the math lab, and even studied with other students in the class and still ended with a B

Professor Pachas pushed me to improve my mathematics and communication of mathematics. The course was challenging. He tries his best to set students up for success in future courses, so it was a good amount of homework and accuracy on exams were important. He is kind and will take the time to meet with you during his office hours.

Honestly, he isn't the worst teacher I've had, but as a freshman, I wouldn't recommend him for your first year. HW is not for a grade; quizzes and exams determine your fate. If you want to succeed in his class, most say to do the HW and go to OH. Very strict grader and lectures will not prepare you for the tests. Do not take if you want an easy A.

He may be a better professor in other areas of math, but as a freshmen I don't recommend. He is a very strict grader and your grade is made up from taking quizzes bi-weekly(then every week) and 4 exams over the course of a semester. There is a textbook for the class but it does not prepare you well for the exams. You are better off another class.

I actually enjoyed his lectures -- Discrete Structures has some pretty interesting topics. He didn't really explain exactly how he wanted you to answer some of the exam questions, yet graded as if he gave you a precise rubric. Homework isn't graded. I would suggest you bring your proofs from the homework to office hours for feedback.

For the people who are actually ready for UCLA, USC or wherever, this class won't be a problem. You just simply have to make sure you don't fall behind, and use your resources to understand math. THIS IS COLLEGE AND NOT EVERYTHING CAN BE EASY OR HANDED ON A PLATTER. Also, Pachas is a supportive teacher who brings the juice while teaching math.

He is the toughest grader. I did all the HW, did my best on every test, but it was never enough because he expects your work to be perfect. He does not give points even if you are on the right track. If the answer is wrong or the way you came to the outcome is off because you didn't separate the limits, you won't get points. I don't recommend.

He's very strict on doing things his way. There's no sort of extra credit or credit for doing homework. Exams determine your fate and are either nothing like the class work or much harder. No sort of review days and besides one study guide before an exam you have to find your own ways of studying. Overall not worth the struggle.
