Goofy guy, but really nice. I took elementary geometry with him and he was very gracious on partial points on tests. Kinda easily pushed around by the class, but stands his ground when he needs to. If you do the homework and show up to class you can pass.

Good teacher, difficult course. He does a lot of examples in class which is good for those of us who have a little difficulty with the material. Tests are difficult but not impossible. Study, come to class, and pass.

Brock is a pretty decent guy. As far as a person and professor I can't really complain. His teaching style is very organized and easy to follow. He grades kind of hard though as far as tests, but as long as you do his optional homework (which I didn't as you can see by my grade) you have a really good shot at passing.

Brock is very intelligent and knows his subject well. However, he is not the most insightful guy as far as teaching. He does provide a few examples from each chapter, but his quizzes and exams are ridiculous. He will send out a review, for example, that might cover a few basic concepts and then give a quiz that is unrealistically difficult.

Great Instructor, but the tests are difficult.

Easy to understand and teaches so anybody can understand.

love this man!

Brock aka Chuck Norris is a great prof. Always there to help when needed.

His hand writing is vry easy to read. He gives out reviews prior to every test and goes threw it in class. Hes very laid back and easy to talk to during his office hours. He allows test corrections for every test which is pretty nice. The homework is minimal and he usually does a couple of them during class. I would highly recommend him.

best math teacher

Very good teacher. Very funny, makes class fun and is easy to understand. Laid back and easy going. I highly recommend him.

Absolutely the best math teacher I've ever taken*I'm getting a math minor so I've taken a few*. He will let you retake a test where you can receive half the points missed. I made an A- my test grades were 52 *the average for the first test was a 40 something * but then the rest were 97 and 96 .

He is great at explaining and is very clear. The homework can be a tad tough at times but if you go to class, ask him for help if you need, or go to the SI sessions if you need extra practice there's not reason why you shouldn't get an A

Explains and teaches problems well. He tells you how he want your answers so if you don't do it like that he will take off points. But very good teacher and has a sarcastic sense of humor. Good class

He's one of the best professor in Math Department. The class is not that bad at all; if you study hard enough you will get an A. Also do your homework because it helps a lot with the further understanding of the material. He gives partial credit on your exam, so however many points you missed you can half of it up by doing a test corrections.

Brock is awesome. His office hours are so useful if the homework is unclear. Redo homework to study for tests and you will do well.

Took Brock for Proofs during the summer. He was unprepared for the class but did a great job anyways. He followed the book and took all his test/HW problems from it as well. He grades very easily and can answer most questions you have. Don't slack and think it will be a breeze, give it your all and get an A! Most of my classmates did that and got B

He's a chill dude who is super chill and specific about what he talks about. He makes the class easy and makes sure that you have every chance to learn the material. He works with you well and is really easy to go talk to and get help from during his office hours. He's a funny dude in class and is very clear about how to solve the diff eq.

Brock is one of the best professors in the math department. He breaks down concepts so they are easy to understand and writes examples clearly on the board. His problem solving processes are always straightforward. He also let my class do test corrections for half the credit back and opened up the webwork homework again at the end of the semester.

Really nice guy and gives a lot of chances for success but the course is hard. Homework is worth 15% and keeping up with it is the best way to prepare for tests (which add up to the other 85%). He gives out test reviews but the homework is more aligned with what you'll see. They're pretty tough. Although on some tests he will allow corrections.

Best professor for all of the differential equations classes! And calculus! He gives test corrections and really cares about his students. Take him!

The professor was a fair teacher and grader. He was pretty understanding, somewhat lenient, and helpful. Had a few friends that didnt click with him, but they were looking for an easy A. Honestly, if you do your work, pay attention, show up, and ask questions - youll be fine.

He's understanding and will work with you! No calculators or formula charts though so get ready for that...

He is a generous grader and lectures very well. Attending the lectures and putting in the work to do the homework should guarantee an A for the class.

Tough grader but in fairness he allows test corrections and can replace lowest test grade with final grade. Reopens the homework at the end of the semester to improve your score.

If you can teach yourself the math you don't need to go to class unless there is a quiz. Calculators are not allowed in the class so Mr. Erwin lets students leave the answer in an unsimplified form. You can always email him with problems/questions and he answers promptly and is very helpful.

he gives a lot of homework to go along with the lectures. fair grader/generous with partial credit, reopens homework at the end of semester.

Very cool guy. Very helpful during office hours. Hands out & works through reviews before tests. Allows corrections to get half your points back. Reopens the homework before the final. Pay attention to problems gone over in class- many times the exact same problems ended up on the tests. DO the homework. Repetition & practice will help big time.

He's a great Calculus II teacher. He provides plenty of examples (although most are from the book), but he also is great at answering questions both in class and during office hours. I'd say he is easily the safest and best Calculus II teacher at Texas Tech University. He despises cheating and will call out when people do it. Pay attention in class

I was nervous about taking Math Proofs, but Brock Erwin made it so bearable! His homework is short and to the point, but still gives you good practice. He is very approachable when you ask him questions both in and out of class. His tests were similar to his reviews. At times he'd go a bit too fast with his lectures, but that is my only complaint!

Brock Erwin is one of the best math professors i have ever had. His DE 2 class is really challenging and will put you through a bit of studying. I recommend taking him for any math class. His homework is hard and he grades a bit harshly. He despises cheating and will call you out if you do. overall amazing lectures and animated.

Took him for DiffEq2, he really makes you learn the material but explains it in such a great way. Will curve if necessary but majority of the class will understand it so be mindful. Cool guy, had a great time in his class.

Without a doubt the best professor at TTU. Make your life easy and go to his lectures, they are all you need to make an A in his class. I've had pretty bad professors that I stopped going to class after a couple of weeks, but he is not the professor to do that with. You will save so much time later studying for exams by never skipping his class.

The best math teacher I have ever had. Teaches clearly and always is concerned if you don't understand something. Higly recommended.

Professor Erwin is one of the best math teachers I've ever had. There is a lot of homework, but it helps so much when it comes to preparing you for the exam. He also lets you do an exam review for each exam, and you can earn up to 5 bonus points. I recommend sitting up front, and showing up to class.

Overall the class is pretty easy as long as you do the work. He gives 5 points of extra credit on the tests if you do the review. He posts lecture notes online in case you miss a class or need to go over something again. He also responds to emails quickly!

He has very clear power points and posts his lectures online if you miss class, or need to review. The homework is easy as long as you pay attention in class. He offers reviews for the tests as well that give you up to 5 bonus points if you complete them. he responds quickly to emails and explains things well.

Brock was a pretty good professor, he explained things well and did his best to answer any student questions. His exams and homework aren't too bad but progressively get harder as the year goes on. If you go to the SI sessions before exams you should be okay. Given that he teaches a very large class I think he does a pretty good job.

It is very clear that he knows what he is teaching. He does a good job of explaining each chapter and answering questions. Although he is tough on his students, he is fair. As long as you attend class and pay attention you should be fine. My biggest complaint was having 20 questions of homework due every Friday and Monday.

Good at explaining and helping understand the concepts of what he's teaching. One of the best Math professors I've ever had. If you'd like to speak with him outside class, save yourself the time and don't email him. It will come off as rude and dismissive to many and oftentimes seeing him after class would get your question answered quicker.

Overall, the class wasn't too difficult. If you come ready to take notes and pay attention in class, you will pass. Examples in class are very similar to the homework. He also uploads test reviews, which are very similar to the exams. He will spend days before exams going over any questions people might have.

Didn't have a bad encounter with him. Very nice and taught the material well. I took it during the summer, so some stuff was not taught, and I had to teach myself but other than that I liked him as a professor.

You will need to devote time to study to do well in this class. That being said, he was a lenient grader and would give out partial credit when he could.

Took this course over the summer. I was probably one of very few students who watched all of the provided video lectures, but they carried me through the class. Homework is done over webwork, but exams are done on paper and scanned (thank god). My only warning is that the summer course pace + asynch nature means it is easy to fall behind.

Brock is the man, getting hammered at the Texas tech UT game, wreckem

I really like the professor; I find him quite funny, though others might not agree. The class was very straightforward, and he has a clear teaching style. Curves tests. Syllabus is similar to any other math class at Tech. If you have a question, he will answer it directly. Some might say he's rude, but he's just straightforward.

Clear from the beginning. Did a thorough job of explaining grading criteria and making himself accessible to us. Despite some challenges, by visiting during office hours and going the extra mile, I was able to pull through with an A. Highly recommend Mr. Erwin and recommend him. If you put in the work, you have nothing to worry about in his class.

Grades pretty harshly, but offers test corrections and lets you know how you will be graded.

Erwin was great for Calc 1. I had taken AP Calc in high school, so I already knew a bit of the material, which helped my grade, but it was not the only reason I did well. Erwin is a great explainer and is readily available via email outside of class. Most of the negative reviews here are from people who failed because of their lack of effort

An amazing professor who teaches a very hard subject which is why there's a lot of low reviews. He's a great teacher, he offers corrections, extra credit for attending class, and drops your lowest grades. His teaching style is one where he wants you to learn it meaning, this is not a class for an easy A. He's always available if you need extra help

Great professor! Practice exam and homework questions line up well with actual exams. Lectures are fairly interactive and he posts his notes, but going to class helps a lot. And he gives a heads up on questions to pay attention to that may be on the exam.

I had Erwin for both Cal 1 and 2. He was great in both, and I am sad I won't have him for Cal 3. He explains stuff well and often goes over problems that are on exams. His practice tests are simply the exam he gave to his last class, so the material is very similar. He does grade harshly for obvious mistakes, but it is usually only a point or so.

I've had pleasure of having Mr. Erwin teach both my Calc 1 & 2, If you're a STEM major, I'd highly recommend selecting him as your lecturer for Calc. His teaching is very coherent and he allows students to ask questions/voice concerns about upcoming midterms/exams. BTW ignore the reviews for MATH1330, they're intellectually adjacent to a carrot.

He goes very off the book. Easy to get distracted, but if you talk to him after class/office hours you will 100% understand whatever it is. Grades off what he wants shown, AI or other videos online might not show exactly what he wants, so definitely go to class when its a test review week. Thorough with emails and quick responding.

Mr. Erwin's alright. He was very open to questions. Homework was tedious but okay—just take notes and pay attention to the test reviews. The only thing I wished he explained more was trigonometry and verifying identities. Tests are based on your process instead of the typical multiple answer choices. His teaching style may not be for everyone.
