He's awesome! Really down to earth. Do your homework and take notes - ask questions if you don't get something, he's down to explain it for as long as it takes. And he's really cool about helping people outside of class if necessary. And he loves big gulps from 7-11

He's a great teacher! He explains in detail ensuring everybody gets his lecture. Some students complained about how basic he explained, but I loved that about him! His quizes and tests always allow you to score more than 100 pts. Be on time, ask questions, and do homework and you'll do just fine! He's a little nerdy but very good professor.

overall he is a good teacher. organized. quiz every thursday which is good cuz it keeps you up to date on how well your doing in the class.as long as you do your work and stay on top of homework its a easy class. if not... then good luck!

This is one of the best teachers ever!!!! He is a funny guy and is always willing to answer any questions you may have.

This is one of the coolest math teachers i've ever had. He says some random things that are hilarious. I showed up to class early and he'd be there so he got to know me a bit. I didnt do very well on the midterm but I assume i did well on the final because i passed his class with A! Just do the hw and be on time easy class!

Great teacher; do the work, attend class and get an A

Math is my least favorite subject and I got a "B" in his class even when I got D's on all tests. The major thing is to do all your homework and show up to class. He even gives credit for your notes. He grades on a HUGE curve... so there is no way anyone could fail his class. He explains things very easily too.

he will work with anyone..you just have to be willing to learn. and dont be rude or else leave school...

This class was really boring but that is just because I hate math. If you make sure you do all the hw and do fairly well on the tests you should be ok. He gives a lot of quizzes and not enough time for each one. Make sure you do the extra credit also because I think thats what helped me. Would recommend him :)

This class was fairly easy. He didnt make hmwk mandatory for this class, but used some hmwk problems on tests and quizzes. You should attend every class! no matter how boring it is. He tends to try to hard to make the class enjoyable. I would definitely recommend this class!!! (AND READ THE BOOK TO MAKE YOUR OWN NOTES!)

I used te stress about math before taking his class. He really tries hard to make it enjoyable. He gives a lot of quizzes and a take home portion in the midterm which helps tremendously. Attend class and do your homework and you should be fine. He does want his students to succed. I would strongly recomend his class.

Willing to help you with any questions. Doesn't collect homework, although doing it helps!... I hated math before.. but he made it enjoyable and i actually learned a lot from his lectures.

He's one of my favorite professors at RCC. Teaches math in a way that anyone can understand and offers a lot of chances if you're not doing so well with the material. Probably the only math professor I'll ever recommend.

He is a very easy and great teacher and drops the lowest test score as well as the lowest midterm score. He will just double the better one. The class itself is boring but a definite A. I honestly think its too easy and not very realistic to how college should be so dont think its always gan be this easy. I highly recomend him.

Prof. Grenfell is a wonderful prof. He allows students to make up an mishaps they may have ie. a poor quiz score. He was a tremendous help throughout the semester and very approachable.

He is an easy A if you do his homework, get enough attandence, and get average points in quizes and exams. It seems that he just writes the fonulas and definition on the board, so you have to learn things by yourself.

really this guy rocks he is so nice and tries to be funny which is actually funny. I learned more in this class then the one I previously took. No homework just quizzes which is good because I'm a good tester. He is overall a great teacher.

get 'em while he's hot 'cause the game may be up. He did get audited after all kiddies. Oh, we students know a pass when we see one, so, in light of that. Take him.

I finally understand algebra! He is a really good teacher. When he demonstrates a problem he shows you every step. His tests are multiple choice which is kinda scary but if you go to class and do the homework (not mandatory) you will do well. Take him!

He's really does know how to make you feel comfortable in class, but he does need to work on upper level math. He only used examples from the book, and he couldn't answer some of my questions. He always tries to help out during his office hours. He will be a good professor when he knows the material. Until then, he is not the best for the subject

Went all over the place during lecture. Jumps from one topic to another. Did improved later one when he started to prepare before class.

he was the best math teacher i ever took at rcc so far. he spoke clearly and lecture notes are helpful for the tests he gives out . i honestly recommend taking his class

I only got a C in this class, but considering how bad I generally am with math, I consider it better than an A! I failed this class twice prior to this, but Grenfell really helped me understand it all! Cant thank that dude enough.

Very Enthusiastic Math Teacher. Utalize his office hours if you don't understand, that's why he offers them, really nice man as well. I had to take this class twice and ended up with a C, very satisfied.

Mr. Grenfell is a really nice guy. He explains concepts really well and has a lot of tips on remembering things and avoiding common mistakes. He didn't assign a lot of homework. His tests usually contained "bonus" questions so even if you missed a couple of questions, you could still get an A. Be respectful and do your work and he's great.

Great teacher and as a good sense of humor. As long as you pay attention and attend class passing should be easy

Best teacher ever! If you failed one of his tests, he gives you a boost to get a better grade.

He is a good professor. His lectures might seem boring, but he knows the material. It all depends how much effort the student is willing to put. I didn't do so well in his class, but it was my fault since I did not pay attention to the lectures. ANyone can pass his class if you come prepared to learn and take notes.

Mr. Grenfell is a really nice guy. Even when he asks a student to quiet down he does it politely. His best quality is his super logical and organized nature that makes it is easy to follow along and know what you are expected to learn. He is very smart, words his sentences precisely, and makes frequent use of domain-specific vocabulary. Take him!

He looks serious but he is a funny teacher. Attendance and participation also count. 100% attendance, no tardy, dedicated my time to get to know each problem. I am glad I took Mr. Grenfells class. If you really want to learn math, I recommend his class.

Great teacher the quiz on first day does not count for credit so don't worry great at teaching step by step

He's super clear when teaching, and uses easy to understand words. Pass the tests, and you will pass , I barely did homework or quizzes and still passed. Take him !

I took Professor Grenfell a while ago and just thought he deserved a good review. He is very polite. His teaching methods are very helpful. He is the definition of a good professor. Go to class, do your homework (for your own benefit), study for his tests and you're good. Simple as that! No tricks, no games, just a great learning experience :)

I enjoyed his class. He is funny and explains things well.

HE WAS A GOOD TEACHER I JUST WISHED HE OFFERED MORE OFFICE HOURS. AND HE COMMUNICATED BETTER WITH THE CLASS. HE WAS NICE BUT AWKWARD BUT HE KNOWS HIS STUFF SO I WOULD TAKE ANOTHER CLASS WITH HIM AGAIN.

his class was hard aff no lie lol. I still passed with an A tho, idk how. His class starts to become way more harder towards the 5th week and his exams affect your grade sm. towards the end I didn't understand any of his lectures. What sucks about him is that he never gave us a problem to do by ourselves. didn't drop so i could see the choco papis

Professor grenfell is THE man . He curves exams,quizzes and homework. Will need to bring the book daily, hes very understanding and encouraging with course material. makes early morning classes fun, has a great sense of humor. Just wish he would teach beyond algebra. Responds to emails in a timely manner.

Professor Grenfell is nice, but often hard to reach. I found his lectures to be informative enough to grasp the information, but additional studying or tutoring outside of class will be necessary. Overall, I would recommend taking his class, he gives extra credit in tests and is easy to talk to if you need anything.

Regarding Math: I become virtually immobile at the thought of anything beyond rudimentary arithmetic. Professor Grenfell's exemplary teaching methods/homework, patience, and kindness have impacted my life tremendously & after a lifetime of fear I am NO LONGER afraid of Math. I would take ANY class Professor Grenfell taught. THANK YOU!

He curves/gives extra credit on every assignment and test. Read the textbook and watch his lectures, and I seriously don't think you could get less than an A. Lots of homework, but if you do the homework, you'll have up to 30 extra credit points from it. Prof. Grenfell is a really nice man, too. A good person.

I was never a big fan of math so I was iffy about taking math anyways. I took him over winter and it was an easy A!! His lectures matched up with the homework every time and never any surprises on his tests. Very easy to reach if theres any confusion you may have about anything. Homework is majority of the class, may seem like much but its not.

Very approachable when it comes to anything. His lectures are a little boring because he goes slow but they help a lot. Homework was all on connectmath with multiple attempts plus extra credit! You are given 2 attempts for each test and you can see what you got wrong on your first attempt. Overall a great guy with a lot of knowledge in stats.

Stats was never my favorite subject but the professor made it better for me. His lectures are pretty boring but the class is easy as long as you just take notes and do the assignments on connectmath. Very easy A and its hard to fail. Plus the professor is very nice and you can tell he knows his stuff.

There was defiantly homework assignments, but there is built in ec. Professor also uses connect math which allows for 2 attempts on all tests. Hint: ask for a second attempt on the final. He is super helpful. Only critique is he left for surgery for 6 weeks, and came back with a different and more difficult teaching style.

Professor Grenfell has made statistics a breeze. He is very organized and wants to help. If you're not available during his office hours, he will make sure that you find a time to meet. He is a bit lecture heavy and some of the material is tough to get through, but sometimes he will let class out early if you cover all the material for the day.

Mr. Grenfell is one of the best professors at RCC. I took his course in spring 2022 and had a wonderful time. Your grade is heavily based on test scores, with tests being 50% of your grade; however, every assignment has extra credit! (Ex. Homework is 11 questions but he only grades out of 10). Anyone worried about stats should take his course.

I was failing in the beginning because I hardly put effort into this class, but he makes it easier for students to catch up. All his HW assignments are available until the end of the semester with unlimited tries at problems. If you fail a test, no sweat because he allows retakes your correct answers, so you just do the answers you got wrong.

He did a good job explaining everything step-by-step and walking the class through problems on the homework as long as you paid attention. Couple weekly assignments on ConnectMath so they can take some time but it isn't too much if you understand it. Lets you have a second attempt on all the tests so they're not too stressful.

If you're nervous about stats TAKE THIS PROFESSOR! He's quirky but makes math easy to understand. You get to retake all tests - just redo the Qs you got wrong, and most assignments include extra credit. 2-3 HW assignments each week, 6? tests total. It's a hard class, but he makes it manageable and helps you out. Also, most math is done in excel.

I had anxiety upon taking this class. I was never good at math I was told Stats was a hard class to pass. Professor Grenfell was awesome! Not intimidating at all like most math professors. He truly cares and wants everyone to pass. HW was on Connect Math online, 2 attempts for Test & Final. Don't be lazy, do all work, and you will pass!

Funny guy, good teacher. Some times his methods are a little difficult to understand, BUT the book helps as well. All homework assignments are online with extra credit on each assignment and unlimited tries. If you do all of the homework, and do OKAY on the tests, you will pass. I enjoyed the online homework software vs traditional wats.

Prof Grenfell is super chill and can be funny. My only issue is that he doesn't upload assignments/tests into the grade book so you never know your grade & assigns a lot of HW. But, when it comes to tests, he lets you bring a cheat sheet. The reason I dropped the class was bc of my class load/work. Overall, good professor.

Class was pretty easy if you take detailed notes and follow along. Book was pretty affordable online. Each exam he drives the grading system so your C can potentially get you to a B depending on how everyone else graded. One page of notes was allowed during exams so write small. Each exam was no more then 10 questions but time consuming.

Super funny, also lenient. Helps with test corrections & other accomodations. Spends entire class time lecturing, if u cant sit still ull have a hard time. Stats overall is pretty hard but he does fairly well in trying to teach. Grades on curve if class isnt doing well. only assigns a few math problems per chapter section. Not assignment heavy.

Great dude honestly, he will actually spend time to make sure you understand the material. We had to use ALEKS for our homework and tests, the modules online were alot but doable. He does test correlations if you do poorly on a test. Grades on curve so the grade you see online is less than what you actually have but is tough to calculate yourself.

Honestly, a great guy through and through. Stats is a tough subject, but he does his best to ensure you have the resources to succeed. He gives extra credit, so you can get points back on the tests if you show you understand it. All assignments are done on Aleks, and you get an infinite amount of tries on them. 10/10 class and prof.

He was nice, put care into pretty much every question students had. He is a bit unorganized with the note taking, but the online work is clear and at your own pace. The online work includes breakdowns of problems, very helpful. He does not fully teach how to incorporate excel (time saver) but it is always available with assignments and tests.

Grenfell was one of the sweetest professors that I had this semester! He is willing to help you, so if you need help please attend his office hours! This really helped me. Everything is done in aleks so you need to purchase the online code for the homework and exams. He takes attendance every time and it counts towards your participation grade.
