was super easy to understand. Just do the homework and study guides and you'll do fine on the test. Very patient too.

he's a great teacher and really wants his students to succeed..very nice and understanding

Really good teacher...i always disliked math until i took his class! he made it really easy to understand and he also gives EXCELLENT notes!

He is such a wonderful teacher, as kind as he is clear. I would recommend him in a heartbeat.

He is by far the best math teacher I have ever had. In high school I was lucky to pass and with him and I get As on all the tests. Notes are given clearly. Attend class, pay attention, do the homework and you will get an A. AWESOME TEACHER!!!!!

He is an awesome teacher; very clear and comprehensible. However, his tests and quizzes are ridiculously hard. Don't expect to get an A.. and be prepared to work hard to get a B

He was an excellent teacher. I also went to the mathlab for minor questions, but pretty much understood everything..he was pretty clear and extremely helpful definitely recommend taken him for math 107... :)

He is very knowledgeable of math he sometimes claims he is a prodigy,which seens to be true,but writes hundred numbers per minute hard to follow and has not patience. He does not seem to help if need motivation for math.

Jeff is the best math teacher i have ever had. I absolutely hated math before taking his class and always struggled with it. He is extremely helpful and NEVER makes you feel stupid for asking a question. I would recommend his class to everyone. He is also a firm believer in partial credit on quizzes and tests which really helps out your grade!!

Jeff is an awesome teacher. He explains things very clearly and always asks the class how they prefer the info to be relayed. He is always available for help in the math lab and is happy to see students do well. Stats isnt the easiest but if you try and work with him you can do very well.

Jeff is an amazing teacher!! He explains things so well and he actually cares about his students. he makes math make sense to me which is the first time since 5th grade.. i took his 100 class and his 107 class and both were put together the same. HINT: DO THE HOMEWORK!! the quizzes hve problems straight from the hw and it even says the problem num

Good teacher!

Don't take this class if you want an easy pass. His quizes are really hard and they are worth more than the test and final. He is doesn't manage his time well in class. If you want a good grade in this class either be a genus or be prepared to put in a lot of extra effort. Out of 41 students in the begging he only passed 7.

Jeff helped me conquer my fear of math! Take him!! He may seem intimidating at first, but he is truly an excellent teacher. DO YOUR HOMEWORK and you will pass. He puts in the extra hours before and after class to help you succeed :)

Professor Gray is extremely knowledgeable in MATH and an excellent teacher. The class was very challenging - summer session usually is. If you are willing to work hard, you will reap the rewards. He is willing to help you understand even if your learning style is not similar to his. What is life without a challenge?

Super nice guy and is willing to help whenever. If you show that you are focused and trying he will do anything to help you understand. Met me at UCSB library b/c I lived in IV to tutor me for finals. Pay attention and you'll get a good grade!

If you are interested in learning a lot -Jeff's the teacher for you. But don't expect it to be easy, because he will challenge you. So if you don't bother coming to class, don't take him. Even though his tests are challenging, he is not a bad guy. If you show him that you're working hard, he'll help you get a good grade and you will learn a lot!!

Jeff is the best math teacher I have ever had. He challenge you a lot with difficult problems, but he does care for his students who are willing to learn. I worked hard and I have learned extremely much this semester. I feel well prepared for next semester. All thanks to Jeff. I will register for his statistics class for sure!!

Jeff is a very hardcore, difficult teacher. He's also extremely accessible, helpful, and wants you to do well. Don't take this class if you want an easy A - but if you really want to LEARN, he's one of the best in the department. He can be intimidating because he's very intelligent, but he DOES want to help you, so just ask.

go to the math lab!

Great guy, wants you to succeed but will challenge you. Make sure to be on top of ALEKS and his lectures and you will do above average.

You have to be comfortable asking for help. He lives in the Math Lab so you can always ask him for help even for his really tough Take-Home Quizzes. Gives enough extra credit for you to get a good grade, but you have to work for it. Homework not required but it really helps if you do all of it. Tough but a great college level math class.

Jeff is a really good teacher. The in-class worksheets are so helpful. He goes out of his way to make sure that students understand the material and you can always find him in the Maths Lab. Tests are challenging, quizzes can be ungodly sometimes, and you definitely have to put in the effort, but you finish the class with a mastery of the topics.

Jeff is an amazing teacher that teaches you math and not formulas. Math can be intimidating sometimes, but he truly teaches you how to comprehend concepts and apply them wisely. I would take him in every math course if it was possible. It's a challenging class, not hard.

Jeff is a great guy who cares about his students and really cares about the subjects he teaches!

Jeff is without a doubt the best math professor I have ever had. He inspires students to want to become independent and motivated learners, so if you're lazy you probably won't like that. Math is a difficult subject regardless, but Jeff has great handouts and lectures that make it more approachable. TOUGH group quizzes that are take home avg hw.

Jeff is a great teacher. He really takes the time to listen to your questions and answer them so you understand. He's funny. Group assignments every week. Lots of office hours to make sure you get the help you need. Grading is very easy and he gives partial credit for answers instead of making the whole thing wrong. Easy going and informational.

First and foremost, HE'S HARD! This is a very tough course. The take-home quizzes are the most difficult assignments. The exams are kind of tough too! However, he's a great professor and extremely smart! He will definitely challenge you to be a better student and use your brain. Pray you get smart students in your group. Studying is mandatory...

What a guy. His personality is funny in a nerdy way and he is extremely smart. Sometimes he has difficulties explaining concepts to the class but he is very approachable and is always in the math lab if you need help. His class is a challenge and he definitely makes you work for your grade but it is not unreasonablely difficult .

Quizzes are challenging but not as challenging as most claim and are extremely enlightening. Pay attention to his lecture and try to grasp a conceptual mathematical mindset and you will barely have to study. Just do the quizzes (don't just ask the tutors to answer them) and do the homework you'll be good.

Jeff has a unique style of teaching that most students aren't used to. He makes you learn the material by yourself rather than teaching it in class. However, if you still need help understanding the material even after doing the homework he assigned, he'll help you out. Quizzes and exams might seem a bit hard, but they are doable if you do the hw.

Great teacher. Wants his students to really understand the material. Goes beyond basic explanations. Often in math lab to offer extra help. MATH 131 is, however, a really hard class.

I recommend Gray for stats. My class was well organized and nicely paced. He hands out packets for each chapter that replace the need to read that headache of an openstax book. He seems to genuinely enjoy teaching- that's always good!- and aims to keep the material light. But hey it's always going to suck.

Professor Gray is good teacher for upper level math. I imagine his teaching style wouldn't fit well with statistics because most people taking stats don't care to learn about math and are taking it because it's a requirement. Professor Gray is passionate, well spoken and knows his stuff. Hate him or love him, but you can't disrespect him.

I loved this professor but he does kinda make you feel stupid when you ask some questions. He doesn't mean to and I'm not sure if he's aware of this, but if you can get over that, he's a great teacher and he really wants to make sure you understand calculus. Super organized lectures. As long as you take notes(!!!) and do the homework, you'll do ok

Professor Gray is a really good teacher! You need to attend lectures, and also it's really helpful to go to his office hours! He gives you homework every day, but it's great because you're studying the material which is gonna help for the tests. Tests aren't that hard tho if you study and prepare for them. I recommend him for calculus!

I took Math 131 class during Sp19, and I just want to say 'thank you'. MATH 131 is very tough, because the MATH 130 at SBCC do not prepare most students for it. But as a Berkeley student, every class here is like this, or harder. This class will give you a sense of what your classes will be like after you transferred. Grind for it!

I am taking Linear algebra over the summer. For a 6 week class it feels super stressful, but it's still doable. Jeff is a chill guy who clearly knows his stuff. He expects you to do the work outside of class to understand the material. I wish I would have taken this class over a full semester, 6 weeks is way too intense for this much material.

I enjoyed Jeff's stats class. I truly don't think it's fair how many bad reviews he has. A lot of my classmates in Spring were just there for the requirement and would get annoyed by having to put in real work. Jeff cares about his students and makes that clear. Maybe if you poor reviewers bothered to show up at his office hours you'd know that. ;)

I really like professor Gray's teaching style. I think his grading system is really good; it gives you a lot of chances to come back from a rough start. He has office hours every week day and is super helpful in them. He grades pretty tough but you do well if you really work hard and know your stuff. Best math teacher I've had so far.

I think prof. Gray is a great teacher. I think he has high expectations for his students and most students aren't used to his methods. You need to put in the work and take responsibility for your own grade - nothing is handed to you. Take this class if you want to be treated like an adult. Don't take this class if you aren't ready to work for it.

Jeff is rad. Lin Alg is not lecture heavy with him - expect to put in the work to learn a lot on your own. However, he is there and ready to help at any time. Super flexible, super nice, very funny guy. Wish I could take more classes with him. Not really sure why people have rated him so badly on here... if you put in the work you will succeed.

I thought his class was pretty well set up for success. He hasnt been posting the answers to homework, or quizzes so i can' go back and figure out things i' not understanding without a lot of extra work. Great teacher and very understanding plus he simplifies things well.I wish he would keep up on grading so i know if am understanding the material.

Im currently on track to getting my PHD. I wouldn't have been able to transfer if I had not passed math117. I went to math lab and struggled daily with problems. Professor Gray worked with me and I passed the class. I am forever grateful for the compassion this man showed me, one of the most genuine human beings you will ever meet.
