Great Professor. Can't say engough about him. Funny but Serious when it comes down to the work.

You will learn in his class. Great teacher. Fun person. He is real. Great math examples. I enjoyed his class. I even tried to take him for my next math class. No luck. :-( He wasn't teaching MAT 104 the following semester.

Greenhalgh is a fun loving professor and he can make math fun and easy to understand.

there is nothing youcant say wrong about Prof. Greenhalgh, great teacher.

One of the best. You will be very lucky if you get him.

Very good Professor...Very thorough when he explains the problem. I am not Math-friendly and I was able to understand him and pass the course.

Great prof. He explains everything and does not go on until you understand it. There is nothing bad you can say about this prof. He's a very good and understandable prof. Well, recommended.

He is really interesting and fun.

Great teacher

He was clear on the topics went slow you need to do the homework for pratice if you are late or absent you miss alot and you are on your own he keeps going .lets you go a little early .I like his style he is very good his approach is gentle yet effective .

Professor Greenhalgh is a GREAT instructor. I labeled myself the worst math student in the world, hated math!!! After taking Prof. Greenhalgh's class, I still don't like math, but I understand it sooo much more. He could get a bit grumpy sometimes, but will slow down if you are stuck. P.S. I had a crush on him!! Although, I think he's a bit bi-pola

Professor Greenhalgh is beyond excellent. His lessons are clear and consistent with the curriculum. His technique and style of teaching out performed any teacher I ever had in high school. I learned more from him In the 15 weeks than I did from 4th grade through 12th grade. I strongly recommend you enroll in his class. You won;t regret it!

The most amazing professor. He makes you feel very much at ease in class. I have not been in a classroom for 20 years and he made me feel that I could anything. I would recommend Professor Greenhalgh, to anybody. I would just wish that the department would give him the Algebra course to teach next. Thank you for a wonderful experience.

He is the best at what he does, makes his student feel confident and welcome in his class. He doesn't move on till all his students understand, and he doesn't mind answering questions. If you are bad at math and looking to understand without being embarrassed to ask questions, he is your guy!

Prof greenhalgh is really a helpful and nice teacher.

The BEST math teacher i've ever had ! Although we get a lot of tests, it actually helps us in the long run. I used to HATE math ! But thanks to Prof. Greenhalgh I actually understand it.

Professor Greenhalgh was amazing! As long as you come to class and do his homework and try your hardest then you will pass! He made Math so clear to me and I was able to pass his remedial course with flying colors. He's always there for his students via email or whenever you don't understand something. I wish I could have him for other math courses

I absolutely LOVE LOVE LOVE him! If you want to pass and actually understand math take this class! He actually cares about us and makes sure everyone understands. He doesn't make you feel uncomfortable asking questions he actually encourages you do. Favorite Professor at BMCC!

He makes math easy to understand he is amazing !!!

Amazing!!! He authentically cares about his class passing the course and will do anything and everything in his power to help you succeed. Explains everything clearly and its open for questions. Just do not be late to his class. He hates it. I wish many more teachers were as committed as him. No text book needed.

I did not understand math almost all 4 years of high school. I came into college, had this professor and let me tell you I understood math so well being in his class, I passed with flying colors. He doesn't really believe in textbooks but he does speak a lot, so if you listen and do the homework he assigns, it will be a easy A!

One of the best teachers I have ever had, really caring and cares about his students. Math is one of my weakest subjects but he made it so much easier . thanks to him I learned how to divid. BIG SHOUT TO HIM ! if your taking math 8 take him ! trust me you will not regret it and no one teaches better than this guy!

SHOUT OUT TO THIS PROF TRUELY ONE OF THE BEST TEACHERS I MET I HOPE MY SON HAS A TEACHER LIKE HIM IN COLLEGE !

Great Professor!! Wish he teached math 51!!! All you have to do is come to class , pay attention and take notes!

legendary professor and person in this school. there is no better teach for math remedial then him, he is very inspirational and empowers you philosophically,as he proclaims to be the guide towards the light, as he truly cares about every single one of the students. please, take his class. you will not regret it.

Awesome professor if you take mat 8 and want to pass take him his technique are wonderful dont show up late and just a great professor at BMCC

If you want to pass Math 8 with flying colors please take him! Hes one of the best professors Ive had within my 18 years of going to school. He has taught me more than any other professor has. Ive never understood math until I took him. I wish he taught Math 150.5.

GREENHALGH IS THE G.O.A.T

I learned things I never learned with other math teachers and he helped me gain confidence on my work.

He's just simply the best professor at BMCC for Remedial math. His lectures are phenomenal and sometimes he gives advice and makes funny jokes. I took other professor but made me even hurt math more and I fail but with Professor I easily passed the course. He email his students once enrolled in the class which is just very kind and helpful too.

This professor should have a BMCC building named after him. He made the lessons understandable and gave simple steps. Quick with email response and super patient. Only wished he taught other Math class levels. I've always felt dumb in math but he gave me the confidence to believe in myself. Thank you, Professor Greenhalgh.

He is so caring and the way he teaches is so helpful. I highly recommend him. He is simply the best Professor.

A Blessing! Please follow the instructions set before you and you will pass this class. He knows how to teach and does so with passion and understanding every one has different ways of learning. Ask questions and utilize effective listening.

Professor Greenhalgh was by far the most superior teacher I've ever had. He raises your spirits while raising your grades. He is ALWAYS available by email and will help you with anything you need. He makes math fun and easy while teaching life lessons along the way. I wish he would teach more math classes!!

Wants students to succeed so constantly reminds them of being on time to class and study. Treats students as he would his own child. Wants nothing less!!!! Outstanding methods of teaching. Absolutely best remedial math teacher in the school. Unbelievably caring, considerate, responsive, helpful.

He really pushes you to do and want better for your self he is a good teacher may come off a little mean but its all for the good

PROFESSOR GREENHALGH WAS CERTAINLY THE MOST CARING PROFESSOR I'VE HAD FOR MATH 8, I WAS FORTUNATE ENOUGH TO HAVE TAKEN HIS CLASS. WISH I WOULD HAVE HAD HIM DURING MY 1ST SEMESTER. FIRST AND FOREMOST HE IS W OUT A DOUBT THE BEST! HIS EXAMS HELP YOU THROUGHOUT EACH LESSON & PREPARES YOU FOR THE FINAL! I CERTAINLY PASSED THIS TIME! THANK YOU PROF!

TRULY AMAZING! PAY ATTENTION TO EVERYTHING HE SAYS, TRUST IN HIM YOU WILL BE IN GOOD HANDS! AS LONG AS YOU FOLLOW DIRECTIONS YOU WILL NOT HAVE AN ISSUE IN HIS COURSE. HE PREPARES YOU, BREAKS THINGS DOWN FOR YOU. HE MAY GET ON YOU AT TIMES BUT THATS ONLY BECAUSE HE CARES FOR HIS STUDENTS! I WISH I WAS TAKING HIM FOR MATH150 /

Absolutly the BEST professor ever! His lectures are easy and understandable for the students, he uses clear and simple technique so everybody can understand even the hardest math. Very respectful, engaging and good as a person. The way he teaches math is iconic, you will get it at once. I wish there are could be more professors like him ...

For me math has been something I have always struggled with. I was going into this course scared that I was gonna fail. I found the best professor ever! Thank you for everything. Do not come late, Only the final matters (70 and above), has his own website filled with review, He treats you as if your his own kid and that is rare. Gonna miss him

Prof Alan is a great Proffesor, If you follow what he say's you will easily pass the class even if your not a math person, my advice is to trust him , he is the best.

Professor Greenhalgh is by far the best teacher I've ever had. Not because he is easy don't think you can come into this class and not work. he is an amazing teacher and he lovessss questions. He is the most patient teacher I've ever come across. DO EVERYTHING HE SAYS AND YOU WILL PASS, COME TO CLASS ON TIME AND READY TO LEARN!

Professor Greenhalgh was one of the best teachers I have had. He removed my fear of solving math and make me really appreciate it. He loves the subject and his students, does his upmost effort to make sure that everyone understands and succeeds. Without a doubt he is unique and irreplaceable.

What can I say, Prof. Greenhalgh is literally the best professor you can possibly take for any math course. He is a caring individual who has very clear teaching methods. Everything you once learned doesn't compare to how he teaches you. If you aren't the best in math do yourself a favor and take him. He builds confidence in his students. Love you!

Best Math Teacher I EVERRRRRRR HAD. Really amazing at what he does . i wish i can take him for all my math classes

Professor Greenhalgh was absolutely amazing. He was helpful and kind, I am very very bad at math and was nervous for this class, but he helped me understand the material and was not nasty about students not understanding like most math professors. I recommend Professor Greenhalgh 100%.

This class was taken online, there was a schedule on when you get there and you look at videos on his youtube beforehand. Since it was online the homework was practice tests. Good professor, little strict but overall good experience. IF YOU HAVE QUESTIONS ASK! He will do his best to set a time and place for you. He has a website, use it. Adore him!

He is an excellent professor and now with this situation is more our responsibility to organize better so we can be able to do his homework; as a result, we can have good grates.

Professor Greenhalgh will keep you motivated in his class. He is always sending emails to keep you updated in class. He is willing to tutor his students if they don't understand in class. He is willing to try his best and help you pass his class if you put the effort. He is understanding and considerate of his students.

Simply the best! He knows it, we all know it. Caring yet professional with a deep sense of humanity and profound interest in his students (ALL of his students) academic success!

Professor Alan is the best teacher you will ever have. He cares about his students, responds to email very quickly, responsible, and genius. His classes are always fun trying to make you laugh every time. If you want to learn math and have fun while doing it, Alan is the best choice. If I could I would take him again, I would without thinking.

Professor Alan is truly the nicest prof I have taken so far! He made the frightening online Math very easy to consume. I'm truly blessed that I chose him as my math professor. I had a huge gap in study especially in Math, he is exactly what I needed to brush up and get up to the pace. Very humble, caring, and understanding. Truly a GEM of BMCC.

Professor Greenhalgh is the best professor for math 206.5. He cares about his students. He sends an email ahead a month class starts to remind his students about the upcoming classes. He gives four quizzes and final, review materials before the test that helps a lot, and drop off the lowest score to help his students to pass or get a better grade.

The best there is!!!!!!

Best prof. His style of teaching helps students succeed. He records his lessons which is great if you need to study/miss a lesson. He's available and answers questions. There are a few tests so study hard for those. Sad the class ended-I will miss him. Tips: Try your best to participate. Work HARD and STUDY. Sydney.

He is the best professor I have ever met. He will give you a free textbook so you don't have to spend extra money to buy the textbook. he will give you practice tests before each test and the tests are close to the questions on the practice tests. If you put effort into the class, you will get good grades.

Professor Greenhalgh is an amazing instructor, maybe as far as being the best. His explanation in each lecture is easy to grasp. He also records every lecture so you're able to go back in case you miss a lesson or need a refresher. You're ONLY graded you based on how well you did in each exam but he also drops low scores at the end of the semester.

Professor Greenhalgh is incredibly sympathetic to his students and caring. He understands that his students are brand new to many of these mathematical concepts, which is a quality most professor's should have.

Professor Greenhalgh is an amazing math teacher. He gives four tests and the lowest score is dropped at the end of the semester. The review test he gives is very similar to the test. If you just do your homework and actually put in the effort, no doubt you will get a good grade. This is the best you will find.

Very charismatic professor ! Strongly recommended ! The best !

MATH 206.5 Lots of Homework (but trust me, believe it or not, you will want to do the homework!) Professor gives good feedback, goes out of his way to teach you. Participation matters! Ask questions! He answers all of them. He encourages you to learn! Look no further! He is the man. I miss you, Professor. You inspired me and made enjoy math!

206.5 He is a good professor, he made review test for each exam, and he also offers tutoring before the test. the best is he has all the class videos so you can watch went you are stuck.

MATH 206.5 I am glad that I take his class. He is an amazing professor. He cares a lot about students' learning. If you take his class, you will learn a lot from this class!!!!

MATH 206.5 I am glad that I take his class. He is an amazing professor. He cares a lot about students' learning. If you take his class, you will learn a lot from this class!!!!

I love this courses!This professor cares students and always show enthusiasm. It needs textbooks.But! He provides ebooks online. Every time we have tests, We finished at 4 even 5 pm.And it is a lot of works to grade. But he tried his best to give grades on the same day! He provides tutoring every week and all emails were responded quickly!

I love him

Im taking Spring23 class with professor Greenhalgh and so grateful. He's a true Gem, caring, kind and knowledgeable. 4 tests and drops the lowest and Final. He uploads each class to his you tube channel. Explains each problem clearly until you get it. Very patient and wants you Pass. Hurry up get him you will love him!

Professor Greenhalgh is amazing! Clear grading. Such an easy class! Very respectful! Highly recommend!

Professor Greenhalgh is the best! I am taking online class with him, he is genuinely hilarious and engaging. He is always available outside the class. Grades very fast. His class is really manageable. With him you will learn so much and even pass with flying colors. I wish I could take him for calculus 1 and 2!

Professor Greenhalgh should be one of the best professors in the world. The lectures are delivered with clear logic and a comfortable pace. He is respected and caring for every student in the class. He always encourages students to ask any questions. Timely feedback for each test and quick replies to emails. Highly recommend taking his courses!

Great Professor! Laser-focused on you passing the course. Very friendly and easy to talk to. He doesn't grade the homework but going to his tutor session will count toward extra credit. There is no makeup test if you miss one but he will take the lowest grade out of 4 tests for your grade average. Very easy to work with! Take his course!!

Professor Greenhalgh is awesome! He's very helping, nice and respectful. His class not difficult at all. Actually, its him who does a lot of job. He explains every problem clearly, organizes tutoring every week. Makes same test reviews but only with different number characters. He really wants every student to succeed. Math is difficult with him!

This professor responds to emails the quickest I've ever seen, records his lectures so you can watch them at any time, and provides weekly free tutoring. He is the most compassionate person I have ever met, and he constantly makes time to assist students in need. Because of how talented he is at teaching, I wish I could take him once more.

Every student loves him. He is such a great, knowledgeable and humble person. He really loves his job. It was an easy class. He grades tests the same day, doesn't give h/w. Drops the lowest score or u cannot take 1 of the tests. Prepares very good for each test and wants you to ace. Such a true GEM, very inspiring! Absolutely suggest to take him!!!

I took him during the summer semester, and he was incredible. He was very clear with the material and very understanding. He loves questions, and will take his time making sure you understand anything that you have a question on. He is a quick grader. I recommend taking his class!

I took this course over the summer with professor greenhalgh and my experience with him was way better than my first one . His method of teaching is the best especially for this course as he goes over problems more than once and he definitely takes time to help prepare you for the final.

An amazing professor, makes Math look super easy, very passionate about his teachings, loves when you participate and really loves when you ask questions. He's super funny, provides you with tutorials and gives you extra credit for attending them. Wants you to pass and drops the lowest grade of the 4 exams before the final. Best I have ever met!

If you are concerned about taking a higher-level math course and don't know who to take, this is the professor you need. He adds waitlisted students to his class. He loves it when you use the "raise your hand emoji" and is passionate about teaching. He is funny, intelligent, and kind This was my second time taking 206.5; he made me love math again!

Honestly, Prof. Alan is truly one of the best. I was fortunate because the class was filled, and he allowed me to take his class. Please take his tutoring session when he offers it. Don't be afraid to email him and ask about your standings. Keep in mind that just because it's online doesn't mean it's easy A, you need to put in the work. Good Luck!!

Trust me when I say this: You'll not regret taking this professor! His teaching style is amazing, he's very caring, and is always there for the student. I have never had this much fun in a class, and i was never this ready to take exams as I was with him teaching the material. AND ASK QUESTIONS!! He absolutely loves questions, which was super fun!!

Professor Greenhalgh is the best college math professor I have ever had. He makes difficult material easy to understand. He really knows how to teach. Homework is not graded. He sets up tests to reflect the same problems you studied in class.WIll drop lowest test grade. Show up, pay attention, ask questions, and you will do well in this class.

Professor Greenhalgh is an amazing instructor! He makes learning engaging and interesting with his wealth of experience. His classes are not only informative but also filled with humor, which makes the material more enjoyable. I absolutely love his teaching style and have learned so much already—can't wait to see what the rest of the semester holds

Answers student questions and accommodates requests. Prioritizes attendance and student success.Uses humor to lighten the mood.Despite math being a challenging subject, the professor's approach makes the class enjoyable and supportive. His focus on student success and willingness to help make him a great instructor.

Professor Greenhalgh goes out of his way to support students, providing his own YouTube videos to reinforce the lessons taught. Missed something? No problem. He creates a safe, welcoming space for asking questions and adds humor and respect to the classroom. A con? He's a Mets fan, nobody's perfect! Overall, an amazing professor. Highly recommend!

He will encourage you to understand all material in a healthy way. Nice work load wont overwhelm you. Available 24/7+++ He will work with you under any circumstance. Do your Homework!

Professor Greenhalgh was my first introduction back into math since high school, Its been almost 8 years. His teaching style was very far and easy to understand. He made math fun not for me but for the entire class with his laid back attitude and fun witty comments. He is a great teacher and I will be sad when I finish his class. Thank you!!

I'm not usually a Maths person, I reckon I put it off for as long as I could but alas I had no choice. I'm glad I took maths with professor Greenhalgh. He insists no question is dumb but the one you don't ask which is very encouraging. He's funny and to my surprise I'm doing well. I would take professor Greenhalgh again even if it was sans maths
