Made statistics an enjoyable class. Has a great sense of humor.

His class is not easy, but its not too difficult either. You know what to expect every day when you come to class. Dont expect any days off though. He seems a little aloof and not easy to talk to.

Good teacher in an especially difficult class. Grading is fair. Exams are challenging, but not too hard. Definitely would recommend him for any other math class. Funny.

Nobody likes a math teacher, huh? but as it goes Brad Krein is an excellent teacher, always respectful, always has time for students. Take him if you have the chance.

Wonderful guy a lot of fun. Very reasdonable tests. Deffinatly the guy to take Stats from

Didn't require homework be turned in, but if you didn't do the work, your grade suffers. Quizzes every monday which are really easy as long as you do the homework. Exams are fairly easy, again, if you do the work. Takes time to fully answer any questions and makes sure you understand before moving on. Good all around math teacher.

I like Krein. He is a super funny and cool guy, fun to be in class. He is not that hard, just like most classes you have to do some homework. Quizzes are easy if you keep up in the class, so are the exams for the most part. I don't know why he is so hated, people are really lazy. He teaches Math very well and treats you like an adult, no down talk.

I took his class years ago. Somehow, made it through this class with a B. Partly because I sat in the front row and paid attention, partly because my brother was in the class with me, and we helped each other, and partly because despite the strange mustache, I found him to be kind of visually appealing. Made me pay attention, anyway.

He really worked to help students learn and was there to re explain.

Krein gives 10 quizes (one a week), 3 tests, and one final. He doesn't give points for attendance or participation or homework-- it's up to you to do it on your own. You really can get a lot out of the class if you put effort, and he'll always answer ANY question you have. His jokes are witty and clever. He's an enjoyable guy and a good teacher. :)

The people on here who say Krein's "the worst teacher I ever had" and that he's so horrible are people who aren't willing to learn and who are just looking for an easy A. Krein is a truly incredible teacher for students who actually apply themselves & put forward the effort to succeed. If youre actually interested in learning, Krein's your man.

Teaches mostly from the textbook, so it's easy to go back and check on what was done in class; explains things well; interactive approach makes class more fun. Exams are the easiest math tests I've ever taken and grading is not too strict. Brad's very smart, but friendly and thus approachable. Homework policy makes procrastination painful.

Brad expects his students to pay attention, be on time, and be prepared. If you do the homework, ask as soon as something is unclear, and put in the time, you will understand the material. He is not one of those teachers who will spoon feed the material to you, but you will come finish class with stonger nueron connections if you take his class.

Awesome.

Just need to say - If you don't go to class and don't do the homework then you deserve what ever grade you get. He helps you when you need it. I enjoyed this class a lot.

Gotta go to class to even come close to enjoying it. He will help you if you need help, just ask! very good and teaching, enjoying the class so far

I dont know why everyone is hating on Krein. I liked his stats class and thought he taught it very well. If you pay attention and do the work his quizzes and test are pretty easy. He grades fair, but definitely not hard. I would take him again.

Krein is not an easy instructor. He is sometimes disorganized but is happy to clear any confusion--the burden is on you. An A in this class will reflect you understand the class very well. His tests closely match what he teaches. He is competent and only respects students that are willing to meet him half way towards their education.

Good instructor. If you need help - very helpful. If you attend class you will do well.Funny

His lectures are entertaining, as he is a very comical guy. He's also actually quite good at explaining concepts during his classes. He's not going to hand out an "A", so expect to work your ass off to earn the good grade, which will show you proficiently understand the material. There are some better math professors, but Krein is great overall.

Great professor! Very clear and patiently answers all students's questions. Do the work and seek a tutor in the math learning center if you need extra help. Math isn't easy for every one and Krein does the best he can to meet students halfway. Do extra problems in the book for more practice.

Don't let all the negative comments fool you, Brad is a great teacher and I enjoyed his class a lot! But you will only get an A if you give the class the time and attention it requires by coming to class every day, doing the homework, and studying before exams. He doesn't collect homework, but there are quizzes every monday to keep you up to speed.

Brad is the man if you are willing to work hard. His test are difficult and along with the weekly quizzes are your entire grade. If you are looking for an easy class avoid it. If you want to learn the material inside and out this is your class. He is willing to help and a nice guy. I would take another class with him forsure.

Alright people, so if you're not a math wizard, expect to put some work in, and I mean a lot. The dude teaches fast, so if you don't understand what he just explained, then raise your hand and ask. As for his grading, he is very meticulous/precise about the format "he wants". So take good notes on how he wants things done. Hard, but rewarding.

Krein is a great teacher with a good sense of humor that I don't think everyone gets. A lot of students seem not to like him and think he doesn't care about his students' success, but if you do what you're supposed to do an A is very attainable, and he is always open to questions. He explained tabular integration to me on his lunch break.

I'm so confused by these ratings. Maybe this is only the case for math 7, but Brad is the best math teacher I have had. He explains things very well, using intuitive analogies. He is willing to answer any question, even if unrelated to the class. Brad pushes you to your limits, which is so beneficial in the long run.

You cannot expect to take his class and learn the material well with his lectures alone. You will have to read (and note-take) from the textbook as well. He was happy to answer questions during office hours. The amount of stuff he expects you to have committed to memory for the final is ridiculous. Nice guy overall, but very challenging.

Given life experiences I had - ranging from deaths in the family, deaths of beloved dogs, losing a job - I was lucky to have this instructor. Material is tough - as higher-level math, can't be expected to be easy. Questions answered thoroughly in class, office hours available for help. NOT easy A, slackers won't pass, but well worth taking.

I liked Brads classes, but he has a reputation of being hard for a reason. I worked my ass off for my As. If you love mathimatics and are not work shy you will be better at it when you are done his class then others cause of how hard he works you. If you're even a little lazy dont take him. I think he's easier on stats but its alot for non math ppl

Seriously, if I can get through this class, anyone can. Math has always been difficult for me regardless of the teacher. I thought this class was challenging but the students getting A's around me probably didn't think it was as hard. Do your homework, ask him questions, you have to try. Brad is kind, funny and a guy that really loves math!

Brad is hilarious! You must attend class in order to fully understand the material. He gives homework which he doesn't collect nor grade-it's up to you to decide whether or not to do it. The final is comprehensive and he doesn't give out a study guide. There's quizzes every week and no extra credit. He's a great professor and can be tough!

Brad is probably one of the smartest teachers you will ever have. Tons of homework, but if you take time to do it well you will be prepared for the exams. Test questions are very similar to examples done in class and/or homework problems. The man should have his humor card revoked though, he is not funny.

Brad Krein is a chill teacher. He goes out of his way to explain the material. The material is difficult and there is a lot of homework but if you do the homework it turns into knowledge of the concepts. He is caring and respectful but it's easy to get lost just listening to the lectures which requires more time outside of class studying.

I really struggled in this class, not because Brad was a bad lecturer, but because I didn't put in the time. He patiently answered all questions during class, meticulously went over tests and quizzes, and was really available outside of class both in the STEM center and his office. He understands and loves calculus, and will meet you halfway.

Brad is the best Math teacher at Cabrillo if you are willing to put in the necessary effort. He has a reputation for being tough, but if you go through the examples he does in class, you will actually understand the material instead of just memorizing and regurgitating it. His tests are fair and he doesn't give an overwhelming amount of homework.

He always try's to make sure you really know the work and will give examples to break it down for you. Very approachable and patient; bring humor into the lesson to make it fun.

Brad is an excellent teacher who genuinely wants you to succeed. Do not be afraid to ask questions if you do not understand something., he is patient and is always willing to help you out. He gives great feedback if you are willing to ask for it and is very fair when it comes to grading. 10/10 would recommend him as a teacher to anyone.

A hard class. But hey, it's math, what can you expect. Brad is an excellent prof. The test isn't easy, but you learn a lot from the class than an easy-A prof. Take his class, study and ask him questions, he is kind and approachable.

His class is challenging but he is happy to answer any questions & help. He also has a good sense of humor so class isn't serious & intense. Every Monday hw is due from the week prior & there is either a quiz or test (3). He does not provide study guides, allow cheat sheets. But if you put in the time, effort & do your work you will pass.

Brade is a nice guy his class is actually entertaining but the class is way too hard. More than half the class dropped after the first test. Unnecesarily hard with grades dont take the class if you havent taken stats before.

I had Brad for two semesters and honestly learned so much from him. Its true his class is not easy, but if it was do you really learn much? Homework is due on mondays so you can always put it off until the weekend. Before Exams he always goes over what topics will be on the exam, so while he does not provide a study guide you know what to expect.

Professor Krein's teaching is thorough and he is more than willing to clarify any questions asked by a student. If you stay up to date with the material you will find his class very enjoyable. Krein's tests are rumored to be hard, what makes them hard is not the material but the fact that there is no study material besides the hw.

You need to be ready to work and study HARD for this class. You will not pass if you dont study for tests. Your grade is based almost entirely off of your 3 midterms and final. There is no extra credit. That being said, he does give generous partial credit as long as you show your work. If you want an A in this class, get ready to grind.

Definitely tough but very FAIR exams! If you study what's covered in lecture you'll do well. He's accessible for office hours and questions, wants you to do well. I always enjoyed going to class. But you won't be able to easily get an A or a B, you have to put in the time. Never once felt like his exam questions came out of nowhere

Brad is hilarious and has great lectures, he assigns a fair amount of homework but it definitely manageable if you stay on top of it. Would recommend if you're genuinely interested in math.

Brad is entertaining and concise. He delivers unequivocal information as a result of his holistic knowledge of mathematical concepts and procedures. His lectures aren't laborious and flow freely. Punctually, Brad shows up to class right on time despite the new learning platform. Understanding incipient lectures is pivotal to succeeding in class.

Brad gets to the point, has plenty of examples, is humorous, and explains the material well. Tests are a big part of this class, but they were fair. He grades them fairly, emphasizes material that's relevant, and asks questions that are in the homework. My only complaint is that two tests felt a little time constrained. Great teacher overall.

Took Brad for 5C and Math 6, challenging teacher but FAIR. Pushes you to understand the material, not for the faint of heart but if you enjoy math and like a challenge Brad is your guy. I love his sense of humor, he always seemed excited to help in office hours. Does lecture directly from the textbook, tests are long for time constraint.

Wasn't TOO difficult. Krein teaches well, he's organized, and clearly states expectations for tests. However, there are daysss of hw, I mean I was staying up till like 2 am trying to finish it sometimes :( If ur super busy I wouldn't rec bc the hw was important to do well on tests, which are most of ur grade Cool dude tho,I still liked the class :)

Took math12 honors so we had additional assignments but workload was very manageable. Wrote his own free textbook that had lots of examples. Really helpful lectures and open to questions, easy to talk to in office hours, really funny! Tests were on exactly what he emphasized in class. 10/10 would recommend. Fave math teacher at Cabrillo

Tough, stressful, yet mostly fair exams (almost the entire grade) that usually reflected homework (always gave generous partial credit). Extremely funny and generally good lecturer, but was often too derivative from book examples and lacked context/explanation. Accommodating (and always in office during OHs) but lacks empathy. Prepare to grind.

Brad is a great teacher and a funny guy; his lectures are direct and there is thankfully no classwork, group work, etc. Calc I might be hard if you are not great at math, but the quizzes/exams are pretty fair. Homework will take a long time to complete but what do you expect, this is calculus!?? If you need help youtube is your friend, good luck

enough with the brad slander, his lectures were clear, he owned up to every mistake (of which there were few), he answered every question that was asked, he even stopped and pushed us to ask questions when we looked confused, he had office hours nearly every day. the class does go fast, dont let hw pile up and ask for help when you need it!

This was one of the best professors ive had! He taught statictics in depth and if you have questions he takes his time to explain them. He gives a lot of homework, but all has to do with what you learned in class. If you want to do good in his class you will, but if you arent going to put in the time in to this class it will be difficult for you
