when you need help, he will help you!

great guy!! if ur willing to actually learn then he is great professor. has a lot of knowledge to share and is always there to help. but if u dont really care abt learning math thn i suggest u find anothr professor else u gona have bad experience. the exams r hard but if u practice the ?"s in the txtbook n do the hw's thn u'll do fine.

very nice guy...i took his math 195 class during the summer....if you go to his class you will understand math...he teaches well...tests are hard but at the end of the course you will know your stuff

At times the teacher, says korny jokes. He also messes up alot, but he teaches very clearly. Even if you dont understand something he will be willing to help you, as long as u dont give him attitude. I mean in the class i thought i was going to hate the class b.c of his jokes but he was actually really great! i promise as longas ur willing to work

he is really hard,he does not grade fairly i think,but he post test pratice on blackboard and it a very high chance that most of the questions will be on the test.

He is a nice guy, with a great spirt for math. he actually cares about helping the students out as much as he can with extra tutoring sessions and extra problems. just do all hw and the problems in post on blackboard n you will do fine! yes his exams are bit hard but its all about pratice! so stop complaining its not him! his a great professor!

He is so awesome, and helpful. He is willing to push you to do you best, this whole summer he spent his time motivating the class because he believes in us. He is inspirational, sure he is corny but he is funny. He gave me a wonderful impression of CCNY and I <3 him. Tests are ok and hw is alot, but its on a cool lvl! Andrea <3 this Proff.!!

He is really funny but he did not convince me to himself. It is cool that he tries to explain everything on his ow and he never uses a book to support himself and he spends a lot of extra time to help students. The only problem I had was that the problems he gave us on the test were way harder than ones we were doing in class. my rate 4/5!!!

He knows his math. Teaches very fast, but ask him to slow down and he will. Never has lecture prepared, but he knows what he's doing. Tests are hard, but study book and BB material and you will pass. Available for 1-2 hrs after class, very helpful, will answer all your questions. Best part about him, his corny jokes! The man funny.

HE'S COOL.. WILL LISTEN TO WHAT YOU HAVE TO SAY AND GIVE YOU EXTRA HELP IF YOU NEED IT..

Prof cheikhna is one of the best professor in the math depat.he is young probably in his 20 ies. he is very funny, great listener, answer every questions you have without anger or cutting you off. the man knows what is doing. very helpful individidual and always motivating you and believe in you that you can doing. he is also very ispirational.

he writes small but hes funny teaches well very few times hes messed up on algebra and fixes it if you dont understand something and after the sec time hes explained it you dont understand hell get mad uses easy examples unless going over hw or you ask him to recommend to others though trust me theres worse

If you are a girl you must take his class. Be little nice to him and an A is waiting for you.

His exams are difficult, but most questions are from the textbook. He will slow down if you ask him to explain something until you understand it completely. He is funny and nice person overall, but his exams are hard compare to other professors.

no, i take back my previous post. he saved my life, gradewise. just scared the heck outta me for a bit..

He's very helpful if you look for the help if not then you get crapped on by his comments. Its true that hes constantly late but its because he also goes to school. He does teach very fast. Also, very generous and very helpful if you have any problem. He will put himself on the line for you if you show him that you give a damn about his class

He is the best prof. Any student can have. You must work hard to get good grade from him. He is fair, we students are used to get easy grade or tests and the get an A. The truth is many students in my class had got A frm cal1,2,3but when they took this prof. They could not pass because he made you work. He is very helpful. He is the best

He seems very laid back but don't be fooled.His exams are tough but grades them fairly. You can catch him in cafeteria if you need help with hw problems. He tries to make the class enjoyable and a memorable one.

Prof. Mahawa is a great guy, do not fall for what some people might say about him. He is very helpful and easy going person. You can enjoy his class and have a good grade.

He Was a great man and very helpful and care about students when I took his classes. Now,he is a different prof. He just and leave.he make no more joke.he is no longer giving the free workshop.however, he is still teaching nicely and clreary.now,it seems like he does not want to help anyone out side of class or outside hi office. I like the old

Great professor, very straight forward and clear. Super fair. Put in the effort and you will do well on the exams

great prof and very responsible individual. extermely fair grading and very helpful. exams are duable if you study. however, he wants you to understand math. I wish all the prof teach the same way meaning he makes you understand theory bihind whaat you do. he is the best

prof. cheikhna is geneous. verey clear and nise. he is very helful and patient. best in ccny

He is a helpful professor who is very funny and nice. Attendance is a mandatory in the beginning in order to not get dropped, but afterwards its up to you. It is in your best interest to attend though since his exams are based on in class examples, do your hw (which means get the book or a pdf) and the tests will not be hard.

He is very clear and patient and helpful. best in ccny math dept

I didnt do great in this class but I came away really liking the guy and felt like i learned the material. For whatever reason I had trouble translating this to the exams. I think it probably just took me too long to get down basics like log and e etc. Consider taking precalc first unless you are really sure you are ready. Exams were on hard side

One of the most helpful and caring professors I have seen yet. Extremely easydropped two tests out of five. Easy grader, too. Available anytime you need help. Tests are easy so study a little harder for the final. Gives you easy ways to memorize formulas. Ask any questions during lecture and he'll stop and help you. Would love to take him again.

Pay attention in class and take notes. Do not skip class. Ask questions if something is not clear and use the textbook. Do some examples out of the textbook for each chapter. He is funny and makes calculus interesting.

Easy A

The most caring professor in whole ccny. Always there for us. We love him Because of his professionalism and his character. Love faireness. He is so funny and hilarious

very nice and fair guy. accent is a little annoying but hes a really good professor. learned a lot and its math you gotta study

He is very helpful if you go to him. Generally he is a very nice professor. Easy A but you do have to study.

Tests are tough, but he provides all test examples in lectures. He is the man, and doesn't want to fail students. But you need study and do hw, that save yourself. If you are above average, I think you could get a A.

One of the few best prof in CCNY, cares for his student, always available to help. most test questions are similar to his lecture examples.

Professor Mahawa is one the best math professor in CCNY. Quick lectures but does practice problems. His goal is not to fail anyone and if you give it your best then you will get the grade you deserve. His in class test are based off his lecture problem but usually your grade will suffer due to dept final.

He was my saving grace this semester. Passionate about math and can teach it well. Make sure you understand all the in class questions and can solve them blind folded

Great professor! Knows his stuff and conveys material well. Additionally he really wants his students to learn. He will go over things as many times as necessary if you ask. Would highly recommend. Makes math fun and is very fair!!!

very inspirational and passionate and caring. Also funny

My dear collagues, you should come to class and participate fully before you complain. Your attitude my friends, are pathetic. I can hear u guys making sarcastic jokes everywhere. This professor actually is really great person who cares about students. HWs are pretty hard but thats it. It's you guys, not the professor whos making this course hard.

Although he does give a lot of HW, he really does care for his students and makes himself very accessible out of class. The course is difficult, but he does everything he can to help us learn it and succeed.

He's a great guy, although he's hard to follow during lecture, when it comes to the exams you end up being fully prepared.

This is one of the nicest Professor I have met on this campus. Made every effort to help outside of class. He even tells you to call him on Skype. Need more Professor like him, who is willing to help even though they are busy. He made differential made easy

Super nice Professor. Most of the questions asked in the quizzes are taken from the problems solved during the class hours. Easy to pass.

He was a really good professor! Super helpful and love his lectures. Also, participation does matter.

Best math professor I have ever had. He's there whenever you need him. At the beginning of the semester he tries to act like he's this mean and strict teacher when he's the complete opposite. Tests consist of problems he does during class so make sure to pay attention. Sometimes its hard to follow what he's doing but don't be scared to ask him.

THE BEST Calculus professor, gives you all the right tools to ace the course, its on you to work hard, do all the HW problems in the syllabus, go to office hours (BIGGEST HELP He is always available to help his students). Very caring and understanding, not an easy course but if you do your part you'll do great.

This professor is probably one of the best professors out there. Things to know: He is very friendly, caring and available, Sit where you can see the board clearly, write all of the notes, even if you don't understand something, do the webassigns, he drops one test grade, tests come from class work+test, final comes from previous tests + very fair

Cheikhna is a good professor because the work he gives inside and outside of class is very relevant to this tests and the departmental final. If you do the Webassign and ask a lot of questions in class, you will have an ok time during the semester.

Honestly he's a great professor with a tendency to drift off into other topics, which while they may be interesting / inspirational can be very irrelevant

If you need help and ask questions, he'll help for sure. Don't talk in his class. If you do all of his HW's you'll do great.

If you do the textbook homework and webassign before a test you will most surely do well. He is such a caring teacher that always puts his students first but he will see right through the people trying to take advantage of him. Review class before final is vital

Approachable and easy to get help from. Study the class notes closely before an exam. Supplement with the textbook and its relevant examples to be comfortable. Your efforts will be rewarded.

He is one of the best professors I've had in CCNY. I genuinely studied for his class and if I could I would only have him for the math courses. His exams are textbook based and very fair if you practice. Amazing professor, you will not regret it!

Very caring professor. I wish every professor was like him. HE SETS HIS STUDENTS UP TO SUCCEED. The only people that do bad are the people that dont do what he says. Watch jhevon smith videos online and his class will be one of the easiest classes you have ever taken.

Cheikhna is a great professor who cares for his students, better put your hard work into this class otherwise you will not be able to continue. Mostly self-study, you learn a lot of things by doing that. Lots of homework, it's really helpful. Make you practice a lot. Do not fail behind. He likes to talk a lot about his life and his students.

Good professor and very lenient grader!

He's very accessible outside of class and really cares about his students. His exams are very difficult, but he does curve a bit at the end of the semster.

I had Cheikhna for two semesters. He really cares about his students. His lectures are based on his knowledge and the examples in the textbook. I like the way he teaches very neat and organized. Exams are similar to his lectures. That doesnt mean you shouldnt study! The best way to receive an A in the class is definitely should study!

Although he gets off track sometimes in lectures, he is a very solid choice who will continue to explain concepts until everyone understands it. He really cares about his students and he wants us to pass! He makes class enjoyable and worth it. Find some past exams and you will be set, as they are extremely similar to the exams he gives.

He's tough if you're new to programming, U should understand the Matlab notes CCNY gives if U want an A in his class. It's not easy but if U show up, do the HW, & show effort he'll give it to U. If U don't put in effort & U can't show that you Understand everything then consider yourself lucky if he gives U a C. learn what's on the syllabus. STUDY!

He's honestly a good professor. Not the best in the world, but he's better than some of the other professors. He honestly cares about your comprehension of the material, but you have to be the one to approach him about whatever you're confused about. He'll curve grades whenever he sees fit. He tells funny anecdotes and motivation. You need to study

He will help you out if you help yourself. Go to his office hours, email him, have a good connection with him, he will be more generous because he sees you care about the class, but you have to participate, show potential and that you understand the material. Study, do HW, take what u dont understand to office, he will explain and simplify it.

Professor is amazing at explaining concepts intuitively so that anyone can understand. Anytime I had a question, I went to his office hours, and he was always there. He truly cares about his students, and motivates us to work harder. He wants the best for his students and curves his exams. I learned a lot from him. Definitely take him!

This is hands down the best professor in all of CCNY. I have never met a more passionate, more caring, understanding, patient and brilliant professor Like Cheikna. I did not know they made professors like this. He does get off on tangents during lecture, but he will make sure you understand the material. Please do your selfs a favor, and take him.

Prof. Diagana is an amazing Calculus lecturer. He doesnt tolerate nonsense. You want to pass, then STUDY! Take advantage of the 2 hours of office hours to ask him questions. He will do his best to clarify and explain everything in-depth. He may even give you advice on tests/quiz. Trust me he may seem strict but he deeply cares for his students.

If you ever want a teacher who wants to teach. He's the guy. He may be short fused at times but when you approach him during times in his office hours, it'll be worth it. He grades heavy, but, you will enjoy searching all over for good resources when he's not helpful. The Organic Chem Tutor was my savior.

At first I did not like the professor however this professor cares about his students. After he saw so many people struggling he dropped 2 quizzes and a test. After many students were worried about covid cases rising he made the final online. He truly cares about his students. He recycles a lot of his practice questions so make sure to do them.

He has good intentions and he wants you to do well. Exam and quiz questions come straight from lectures, so make sure to understand and do them properly. If u don't understand his explanations, learn to use outside sources bc he is a bit cranky when it comes to repeating himself. But, overall, he makes it so that you can do well in the course.

The professor is really lenient with grading and tries to give you as many points as you possibly can. If you have any problems go to his in person office hours. He hates talking to a person with no camera. Overall he is one of the better professors I've had in CCNY. I took his summer course.

He is a really nice guy, fair and has every students interest at heart. Gets irritated sometimes if you forget what he teaches in the last class or in the same classes. He makes mistakes from time to time when teaching and setting test questions but he is human. Awards extra credits for those who actively participate and respond during lectures.

He's a great professor compared to most from ccny's math dept. He is more than willing to help after class (if you catch him), and he's a very fair grader. He makes mistakes during lectures, but if you catch them he gives you extra credit. Lectures are super easy to follow. Wish he were teaching Calc 2 this fall.

Amazing professor, actually cares about students and teaches concepts clearly, encourages questions & participation & goes out of his way to help students and make sure they understand concepts Gives partial crdt even for wrong answers. Few quizzes, 2 midterms, and final, drops lowest midterm and quiz. Makes time even outside of office hrs to help

Very caring professor. He goes off topic sometimes, but he means well. He makes some mistakes when he is writing on the board, and he encourages people to tell him when he does. He offers extra credit sometimes, so be aware of that.

This Professor is the head of the Calc department. He claims that he goes fast when giving his lectures, but it was at a reasonable pace. He makes frequent mistakes when lecturing, but if you point him out on it, he offers extra credit to go towards the next test. He favors students that are actively participating or putting in effort.

Don't listen to people complaining about him hes one of the best teachers in the department. He genuinely wants his students to do well and tries his best to push students. If you cant do well in his class u dont deserve a college degree. He gives you literally all the tools to succeed. (took him for multiple classes)

He's one of the best professors in the Math Department. His quizzes are straightforward and he usually gives practice problems for his exams. He's also the Calc 1 supervisor so he writes the final. A lot of people ,ay not see it, but he generally wants you to pass. It's up to you to do your part in studying and practicing. Take him if you can.

His class is formatted to maximize chances of passing. He is very caring and can teach well. Go to his office hours; he is more than willing to help, and is pretty good at teaching how to solve problems the "easy" way. Would 1000% take again.

All you need to do is attend the lectures and practice the problems he did in class, and an 'A+' is guaranteed.

Took professor Diagana for calc 1, and then for calc 2 over the summer. I would say he is a very solid professor. He does make alot of silly mistakes during the lecture, so you do have to correct him from time to time. He give you sample exams that are almost exactly like his actual exams. He is very caring and helps you as long as you show effort.

He's made this class interesting, and I did learn a lot. He was very honest and prove many times that belief that calc 2 is harder than calc 3. Take this class and his advice seriously otherwise you'll regret it. Also make sure to practice a lot because I can guarantee you if you don't practice, you'll fail this class.

Professor Cheikhna may seem harsh, but the truth is that he wants you to pass. Lectures are recorded and he provides practice problems that are similar to his exams. Lowest midterm and lowest quizzes are dropped. I would really recommend you take him because he generally does care about his students passing. You just need to put in some studying.

He is a great teacher he does go on rants sometimes for 40-50 minutes. His lectures could not be made any easier it is math after all. He uses the textbook to teach, and records lectures,don't have to buy book. His practice exams have all the questions that will be in his exams. He goes over questions that will be on exams in office hours.

Professor Diagana has his flaws. He makes a lot of mistakes during his lessons, goes on rants often, and can have an attitude problem sometimes. However, deep down, he cares about his students, especially those who come to his office hours for extra help and tutoring. I dropped out of Calc multiple times before until I passed with this professor.

He is an amazing teacher, he knows how to teach and make topics super simple. Whatever examples he gives you in class study those and the homework problems on the syllabus and you should pass. Expect to be given life lessons and also expect him to go off topic from math for a bit. He is a great teacher and I hope I have him in the future.

Knolwdgable and easy to deal with. I fully understood calc 201, the exams was not easy, however, he discussed all of the exam ideas.

I took him a few semesters ago and he is easily one of the best if not the best math prof at CCNY. His lectures are easy to understand, but as the others said he will stray away for like half the lesson 😭. He also gives very thorough exam reviews for every exam and will upload them on blackboard just in case you can't make it!

The professor can get sidetracked, but he cares about students and offers valuable resources like practice exams. I found unstuck study and the free textbook really helpful for studying and staying on top of the material.

He is great at teaching and makes everything really simple. His office hours are also very helpful, and he even does online reviews before each exam. I wish I could take him for all math classes.

He has quizzes biweekly and make sure you bring a printed out syllabus on the first day. If you're confused just go to his office hours and he does reviews before every exam including the final exam. Lastly he makes things easy for people to understand. I hope I'm able to take his class again for the more advanced math later on.

He is a good professor and really wants his students to succeed but you have to but, in the work, in order to pass the class. If you are confused on certain topics go to his office hours because he really takes his time to go over the topic and even will still longer to make sure you understand the material. His reviews are really helpful as well

Participation is really important for this class. If you show up, answer questions (or ask them) in class, and go to office hours chances are you'll get a pretty good grade. He's very fair and if he sees that you are trying your best he will grade accordingly. He gives good homework as practice and explains concepts well, and answers questions too.

Y'all these reviews are overreacting. Cheikna is a very nice teacher that cares about his students. Yes he like to yap but he will still make sure you understand. I recommend his class 100%

He definitely is a crazy dude but he's genuine and cares for students. In lecture he might seem strict or go off the rails a lot, but come on, he teaches the material and also RECORDS every class. He doesn't even take attendance. If you're taking him Calc I, realistically all you need to do is watch the reviews for the midterm and the final. Easy

Amazing teacher who cares about his students. If you try you will get a good grade

This course might be challenging. However, Professor Cheikhna is not that bad. He really tried his best to go over the concepts and wants every student to participate in class as learning. POV: Some of the students did not care about the class and made themselves difficult. Go to office hours & put in effort, and then you will be adjusted.

Lectures are solid and he posts them online. The practice tests cover everything on the exams so as long as you study hard you should be good.

He rants and rambles a ton, wasting class time, but when it comes to exams he gives out free points and drops your lowest so I don't mind the droning on and on. He gives practices identical to the exams and preps you for quizzes. Just go to office hours, do your WebWork, and don't sleep through lectures and you'll be fine.

He is THE GOAT. Any exam, attend his reviews because it will be nearly carbon copy. Applies to all his classes.

He can be pretty harsh at times and goes on quite a bit of tangents but he teaches calculus pretty well and his exams are exactly like the questions he does in class so if you pay attention, you'll be alright.

The professor goes above and beyond for his students but don't expect him to hold your hand. He provides all resources you need on brightspace including recorded lectures for you to succeed. Quizzes and exams are for the most part based on what he went over in class and the homework. Study up on algebra and trig and you'll do just fine.

On the first day, he seemed rude. However, he quickly grew on me. He cared about his students and provided many resources to help us pass our exams. As a bonus, he gives exam reviews which are almost identical to his exams and ends up adding 5-10 extra points on every exam too. Yes, he does go on rants… but they are interesting to listen.

Take him if you can, you won't regret it

- Adds extra points on exams (3-5 points) - Removes lowest 3 quiz grades and 1 exam - Quizzes are online but code is needed - Homework is not mandatory but worth it if you want to pass (I did like less than half and got a 98% : they are worth 5% of your grade) - Practice exams are SUPER similar - Good professor, cares about his students doing well

Do your hw, do your work and you should be good. Office hours are highly recommended as he is willing to help those who are willing to learn. Yes he gets tangent at times but his exams are clearly fair.
