Classwork all you do is listen to his lectures, he shows/explains how to do your homework assignments. If you dont understand the problem just ask for help/speak up and he will explain it until you understand it. All the work comes from the book. Quiz/test/exam are base on your homework.
Very Clear and Fair. If you show up for class and do the homework you should receive an A or B.
I highly recommend him. He was hands down the best math teacher ive ever had and im lazy and hate school. He is a super cool teacher and everything is super clear. He givs hw then the next day asks what trouble u had problem with then does it on the board. Then teaches gives classwork, does that on the board. Then gives hw. Best teacher ive had
I used to hate Math but because of him. I like it more. Highly recommended. It has been fun to study with him.
I now make friend with Math because of him. He is my no.1 Math teacher. Highly recommend.
I hated math I could never grasp the concept which was weird because i used to love math in middle and high school. I took this math from two other teachers who were absolutely HORRIBLE!!!!! I had almost given up on math when I took his class OMG i actually had fun doing the work and it was sooo easy! He IS ABSOLUTELY AN AWESOME TEACHER!
He is AMAZING EXPLAINS everything, doesn't mind helping and he will make sure you understand, I'm not even in his class and I still go to him for tutoring, he knows all the short cuts and is HELLA kick back! you still have to earn your grade
Mr. Isam is really the Best math teacher. If only I could approach life as he does math. I'll be much better off. But he's patient and sensitive no question is a dumb question. Very humbled guy and stands on his word.
Great teacher!!!! Get his class!!!!
soooo AMAZING love THIS GUY!!! HE IS THE ABSOLUTE BEST MATH TEACHER EVER !!! i HATE MATH AND HE MADE INTERESTING AND EASY!!!AND HE'S GOOD LOOKING ! i RECOMEND TO ANYONE
Professor Dudum is a great Math teacher, I wish I could take him for all my math classes. I hated math prior to taking his class and now I love math. My comprehension and confidence has been boosted from his instruction. As long as you come to class and give the effort to learn you will do well. You have to do the homework.
Best Math Teacher i have had LOTS of homework but he explains everything so clear that you never struggle
best math professor
Mr. Dudum is a really good teacher. I was worried about taking a math class in the summer, but Mr. Dudum explains things very well and very clear.
I want to take classes he teaches that I don't even need just so he could teach me again. It's a joy simply being around him, he is a great human being and an astonishing teacher. If you have the pleasure to take his class, enjoy every minute of it!!!
my God... he can change your life... give you the tools to be a math master, i canot tell you enough that hard work pays off in that you get a good grade but more important he makes the material so easy to learn and you will want to go on to calculus after him...Dudum for life!!!!!
He is such an amazing professor! He is the best professor/teacher i've ever had for math! Super patient and explains material really well. As long as you pay attention and do the work, you'll be fine! Quizzes every MWF, test on every chapter, and a final. Took this class in the summer and did really well! Love professor Dudum!
The best math teacher at city. Lots of homework and quiz but that's only because he really wants you to understand the material. listen, do homework, and form study groups passing the class will be easy.
Dudum says on his first day. Math 90 is not like 60 or 40 and I will not go as easy as with 40 and 60. For math 90 he goes at a really fast speed, he is like 2 chapters ahead of every other professor. Skips small steps thinking you know it from 40 and 60. He is not very avaiable on office hours and he expects too much. Don't take him for math 90!
Dudum has truly ignited my love for math. He is not only attentive when needed but also has innate ability to inspire and give exceptional words of wisdom. He wants you succeed and see's a student to the end if the work is put in. I feel lucky to have had the opportunity to take an expedited math 4o & math 60 class with him this Spring 2015.
I took professor Dudum starting all the way from math 40 up until math 110A. He's an amazing professor that genuinely really cares about his students passing. Quizzes every week, and chapter exams. You have to study in order to pass the class. If you're having a tough time he's very approachable and available in office hours. Not a boring class.
He is amazing in all ways man if, u take him class you gonna love it.
Great teacher, made math really fun and easy. I hated and feared math before this class, but now I'm fine. Homework every night, quiz every week. Test material is clearly covered before the test. Just a good person all around. Taking his class for 60 too.
Great teacher, who really knows what he is doing. I failed Math 90 in my fall semester with another professor; I didn't understand the material at all. I now finally understand the material, I actually forward to math class now. Math is actually fun if you understand it, and having a professor who knows how to teach it makes all the difference.
This teacher is really awesome. I took math 40 and 60 and 90 with him and I am going to take his class for 1A I really enjoyed every second with him. He is too easy because he knows how to express the ideas in an easy way. I would love to say thank u soooo much Mr. Isam for your efforts to improve my level in mathematics. Plz go for 1B and 1C.
Amazing professor! In order to pass 110A attendance is mandatory! Do the assigned hw every night or else you won't get a very good grade. He emphasized this multiple times throughout the semester. Definitely harder on grading quizzes and exams then his lower division math classes, but that's expected b/c it is calculus. Definitely take him!
Good teacher, and funny guy, I like his attitude
Mr. Dudum has such a way with words. It's almost impossible to misunderstand the material. He used to struggle with math before becoming a teacher, so he is patient toward those who are a little slow and he KNOWS how to explain things in a way that's absolutely CLEAR. You'll pass his class with much more confidence. Try him.
Incredible teacher. He will truly better your math perception and understanding.
He is a good teacher. Covers a lot of materials in general. You can follow up the class even if you are not very good at math. Needs to do homework weekly but he doesn't really check them. If you get good marks in quizzes, you are most likely to get an A! GO FOR IT!!!
Isam Dudum is a patient, generous teacher. No question is too dumb! Every question in class, without flinching, he backs up and reviews what he wrote on the board until the student/class understands and will NOT move forward until he sees that everyone is with him. This teacher has changed my life. For the first time---I really enjoyed math!!!
Dudum is a gift to calc students! His lectures on even the most tedious chapters are really interesting. He is kind, funny, and approachable, and is amazingly gifted at assessing whether or not the class is understanding the concepts, and if not, he will go back and explain down a different route. He helps you learn the why, not just the how.
Great teacher, always explaining everything to make sure everyone in the class understands it and explains more if he must. Every class is a must if you want to understand the material and hw is also important for the teacher because most of it will be on tests.
Most incredible math prof EVER! Truly cares for your success, never makes you feel stupid for asking questions, is available outside of class, repeats material until you understand it. Quizzes once a week, drops the 3 lowest quiz scores. Quizzes make up 40%, exams 30%, final only 20%, so show up do the work and you'll get A. Plus he's pretty HOT!
Hands down best math professor EVER!! He easily makes you love math even more. Lots of homework (which isn't bad); all quizzes/exams are based off it, so make sure you do it! Super patient, very clear, kind, and organized! Wish he taught up to linear algebra, annnddd he's really really handsome! ;)
The best math teacher I've ever had. Took his math 60 class over the summer and I wish he could teach all my math classes ever. He made everything really clear and easy to understand. Lots of homework and quizzes but that's how I really learned, he asks if we had questions on the homework and we all go over them together.
Amazing professor! Inspiring and wants to make sure you learn the subject. Never in my life have I ever understood math before. He should write a book! Thank you Mr. Dudum for being awesome.
Guy is Awesome! Really knows how to teach and wants to help everyone. You can definitely see that he cares. Grading is super lax, gives points out in fractions if I remember correctly. He's also hilarious and might be the coolest older gentlemen on campus, Next to Physiology Prof. Reyes. Take him, you wont regret it.
Awesome teacher. Make sure you do your homework and you'll pass the class. Don't be afraid to ask questions from last nights homework. He's very approachable and helpful and wants everyone to pass his class.
extra patient!
Just one thing he is the BEST for math. Thank you, professor, I learn a lot and now I like and understand math better thank to you.
Mr. Dadum is such an amazing teacher, he's not only very smart but caring about his students. As long as you do your work and pay attention, you'll succeed in his class, because he makes even the hard stuff much easier to digest, thanks to his patient and funny way to explain things. He definitely made enjoy math. I'd take any class he teaches.
Prof. Dudum is the best teacher I've had at explaining algebra in a way you will understand. He takes time with concepts and shows you different ways at looking at a problem to gain perspective on how to solve them. Homework is a MUST! he is real approachable and is willing to work outside class if need be. I highly recommend him. Great teacher!
He is amazing. I'm already planning on taking math 60 and 90 with him. Very clear on the materials. Just have a lot of homework but is pretty easy. Quizzes every Friday and a chapter exam. Gives breaks down on the quizzes and exams. Easy A if you do the work
I've never understood math till he was my professor. Best professor ever!!! His lectures are clear and understandable. He will explain to you until you truly understand the work. This is my third time taking Math60 and the professors before were either too boring or rushes through the chapters but Dudum takes his time. Too bad he don't teach math80
He is an amazing professor take him!!!!! He cares about you understanding the material and the mathematics behind every equation. The only thing is that you have to do the homework. He basically leaves homework everyday, but its worth it.
He is the best math teacher I've ever taken. He is patient and is not condescending like other teachers I've had. He really takes the time to show students how to look at algebra and gets you to think about problems in different ways. I passed his Math 40 and liked him so much I took him over the summer. Summer class is INTENSE so be prepared!
He is a tough teacher for sure... if you only want to go to class and hang out then don't register for his class. he respects his students, super fun lecture!!! I never ever had such a teacher that makes math class so much fun, I enjoy his class a lot. just do your best in class(do hw; go to class; pay attention on class ) you will be fine
Professor Dudum is the BEST math teacher! He is respectful and has an ease about him that transfers into his explanations. Ask questions w/out fear of emabarrassmentWeekly tests helped me get over my fear of tests and the homework helped me pass every test. Attend class, study, do all the homework and I will not only do well but u will understand.
Average straightforward teacher. If you struggle with math, he works with you. Go to his office hours. Such a nice and understanding teacher, really open to questions. He assigns homework every single chance he gets so do them or it will be super easy to fall behind.
Mr. Dudum is honestly the best math teacher I have ever had. He really makes sure that everyone understands the material and has a quiz every week that really prepares you for the final. One of the best classes I have ever had. Hes super nice and thoughtful to his students. Wish he was teaching Calc 1. Def should take him if youre willing tolearn
Mr. Dudum is an amazing Math Instructor. Although I don't get his jokes in class, everyone else is having a good time. The lectures are amazing and gets in-depth when a student needs help with the content. There is homework everyday, I didn't mind it. Highly recommend taking Dudum for your next Math Course.
I Love Professor Dudum so much. I've tried taking math 60, four other times with other professors and I failed every time. Dudum explains every lesson so well with care and compassion. He really cares about students and loves his job. So long as you do your homework and get help if you need it, you will do well in this class! HE'S AMAZING!!!!!!!!!!
took him for math40 & if i was taking math90 id take him again. FRIDAY QUIZES MATTER MOST. Then chapter exams, then homework. Lectures are easy to understand, more then happy to answer questions to make sure you understand. He wants you to pass, but you need to MAKE EFFORT/SHOW UP 4 EVERY CLASS and you will get a good grade. very patient, good guy!
Hands down the best math teacher EVER. I gained confidence on his math 60 class and I am not afraid of math anymore. He is strict but he respect his student(never misses one single class in 2 semesters)No extra credits, you earn every single point by your own hard work. Kudos for you Prof Dudum!-girl who owns Martin guitar
Amazing Teacher I had for my first year in college. Always check in for you when you need help. 2 or 3 homework's a week easy quizzes if you do the homework and taking notes in class. recommend for people wo taking math 60 with me.
Good guy, you can tell when you meet him that he cares for his students. But he is a challenging teacher. Gives tests every week that really make or break your grade and grades tests harshly. Gives out a lot of homework everyday and his teaching methods are dragged out and rushed.
Amazing. Period, point, blank
A very good math teacher. Students in his classes are lucky.
Its no doubt why he has so many good reviews. He is the best! His lecture is so organized, and he is caring, inspirational, calm, and hilarious. His grading system is very clear and fear. There are assignments after each chapter, one quiz each week, three exams, and one final. I really appreciate that CCSF has a wonderful Math teacher like him.
If you're going to take a math course, it better be with Dudum. He is organized, consistent, approachable, knowledgeable, and you can tell he really wants you to understand the concepts. There's a quiz every Friday, end-of-the-chapter tests, and a final. You won't ever regret taking his class.
VERY merciful grader. Can get incorrect answer but still get most of the credit if your setups are mostly correct. He is excellent at distilling down math concepts to exactly what you need to understand to succeed, and making sure the students get the logic behind it as well. Excellent teacher, highly recommend.
Highly recommended. Good teacher, grades very fairly and very willing to stay after class to answer questions etc.
He is amazing, I hated math to be honest with you. But he made it so much easier for me to understand the subject, he is very caring, loving , forgiving and merciful. He takes late homework and cares about his students.
If you can get into his class you won't be sorry. He gives a lot of hw, but it really helps you to learn the material in order to pass the weekly quizzes and exams. His lectures are very easy to follow and take notes on. He is also very fair with his grading policy so its almost impossible to fail if you put in the work. I would recommend 100%
Isam is a very good professor, and whether you're great at math or struggle with it I recommend taking him. He's very clear with what he expects of you, and is very generous with his grading, often giving partial credit for setting things up right, or demonstrating the right process of thinking.
Very clear and specific on grading criteria; passionate about mathematics principles by deriving formulas for the class. Lectures compromise of a lot of in-class practice examples. Overall a very kind and caring teacher. Unless you're very self-disciplined and seek rigor, professor Dudum is a great instructor.
Dudum is one of the best teachers I have had in my entire academic career. He has the gift of teaching and has truly mastered it. He is able to take complicated problems and simplify them in a way that every student can understand. If you have any work ethic at all, getting anything lower than a B would shocking. Enroll in his class ASAP!
I can't believe I passed math class for once (WITH AN A). Everyone should be fighting to register in his class because he is the best teacher you can find. He is very clear in teaching the material and will make sure you understand it. Just take notes, do homework, study and you will pass the class easy.
Very caring. Great lectures . Is always available if needed outside of class. Will slow down if needed and will always check in with you one on one to make sure you are getting the material . I miss this class a lot!! I wish he taught calculus more often.
Isam is very clear when he is teaching the concepts and examples about the class. He is very accessible and he will walk you through every problem that you don't understand. Quizzes once a week, drops the 3 lowest quiz scores. Quizzes make up 40%, exams 30%, final only 20%, doing all the homework 10% is the key to pass and get an A in this class.
Hands down the best math teacher I've ever had in my life. I think I might actually be good at math now. I had him for Math 60 and promptly followed him to Math 90. I struggle with ADHD, and I found it very doable to follow his lectures. He also creates a comfortable environment to ask all kinds of questions. Thank you Professor Dudum.
Professor Dudum was an awesome, caring, and considerate teacher, not a hardnose. He genuinely cares about helping students and it shows in his office hours. The weekly quizzes and homework are paced well and is lecture style is not rushed. One thing to note, he may be less rigorous than your next calc 1 professor so be prepared to shift gears after
Isam seems a bit new to online teaching, but he was able to pull it off successfully. Isam was always willing to assist with clarifying homework problems, and he graded fairly (and, IMHO, was pretty generous). Attendance was mandatory in the sense that one post per week to the homework forum was required. Overall a pretty easy class.
Isam is amazing. Clear grading criteria, very consistent with the work required every week; 2 homework discussion posts and 1 quiz. Did not feel like 5 units, plus he would send us reminders on Canvas before its due so we dont miss out. Highly recommend him for all math classes.
The professor was great at helping us getting our homework done. The class is easy, and I didn't feel overload with homework.
Professor Dudum was fantastic. I took his course asynchronously during Covid, and I was initially slightly annoyed at how much online discussion was required for the course. But after a while, it became clear that talking over the material with classmates was actually super helpful. Attentive, helpful, and insightful. Great teacher!
Prof. Dudum is amazing! Get ready for the usual math class amount of work. The discussion posts that are made online are really helpful as we can get help from other student & the professor! If you watch and read the content he gives, you will definitely pass the class because it is helpful!
Summer class so super fast. Very open to going over questions you don't understand. Didn't make you feel dumb when you didn't understand something.
I took his class during the summer and it went by pretty fast. He was able to give clear lectures and good feedback on your homework assignments whenever you are struggling. There are quizzes once a week and the more you practice solving problems, the better you will do on the weekly quiz. I recommend him to be your Math 90 professor.
If you struggle with math, I'd highly recommend Isam. He's a very caring person who cares about your future!
honestly everything you want in a teacher - patient + ALWAYS willing to help - super enthusiastic about the material so you're more motivated to learn as well - clear and concise lectures only thing that was a little inconvenient was that he doesn't use canvas (except for messaging ppl) so you don't rly know your grade unless you ask or something
His class was the highlight of my day, he had the most amazing lectures. I wish that I can go back and retake his class just for the heck of it. He is the best math teacher I had in my life he made math fun and understandable. If you have the opportunity to have him as your math professor, I 100000% beg you to get him.
Stop reading now and enroll in Dudum's course. Very helpful math professor. 100% recommend for math 90.
Professor is great. His lectures are very meaningful and understanding. The only thing that sucked is he gives out weekly quizzes not open note.
This professor is absolutely a wonderful professor here at CCSF! His lectures are VERY clear and concise, and his lectures basically help you solve all the problems you don't understand at all before the next lecture. He really cares about his students and I would definitely recommend you taking his class if you are willing to take Math!
He is the best math instructor I have ever had.
I've struggled with math a lot throughout my life, but the way he teaches will make you appreciate it and rekindle confidence in yourself. He knows his students have different ways of learning. His lectures are understandable and also willing to go out of his way to help you. Just be ready for weekly quizzes (do the homework) TL;DR GOAT TEACHER
Respectable/good teacher and provides meaningful feedback.
Professor Dudum is one of the best math professors at CCSF! The class was super engaging and his lectures were very structured, organized and can be funny at times! The homework is optional but highly advised for the short weekly tests and exams. Highly recommend taking Professor Dudum!
This is the worst professor ever! I listened to other comments and took his class. You even call this a professor? He unable to communicate effectively with manner, even if you being polite and doing nothing wrong. I will never take his class again.
A lecture-based class. It's very, very easy to get an A, just go to class and do the HW (neither are graded). Quizzes are weekly but easy. He tells you exactly what will be on all tests, quizzes, and the final. He's very fair, understanding, accessible, and easy to understand. If you're behind, he will help you get back on track.
Professor Dudum is an excellent math teacher. Attendance and homework are not mandatory, but if you go to class and do the homework you will succeed. Your grade is composed of weekly quizzes and a few tests. He outlines clearly what each quiz and test will cover. He is always well prepared to teach. I had a great experience learning in his class.
I'm not very fond of math (sometimes) and was worried about my performance; however, Prof. Dudum changed that mindset. He's punctual, diving right into lectures with examples, and gives time to try some on your own. Thumbs-up for providing quiz/exam breakdowns!! Overall, he's straightforward, and if you're confused, don't hesitate to ask questions!
I was so nervous to take a math class again, but Prof. Dudum is incredible. Gives very consistent, clear, and timely feedback in forums and via messages that is rare for an online class. I am genuinely considering taking another math class because of him!
Probably one of the best professors I've had at CCSF. Genuinely does want you to succeed and do well, interacts with students in the discussion boards every week, and provides incredibly helpful advice towards correcting mistakes made on the homework and quizzes. If Professor Dudum is an available option for a class, 100% take it.
Amazing professor. I hated math for so long and struggled in high school, but prof. Dudum genuinely made precalc my favorite subject and I would 100% take his class again. I actually enjoyed his class so much that it made me confident I could succeed in engineering, and that is my major now. He has super clear criteria for tests and quizzes.
Professor Dudum wants his students to succeed in and outside the classroom. He's cool to talk to and makes an effort to remember your name. Yes, the weekly quizzes are tough, but the work you put into the hw will determine your grade.
Professor Dudum is just amazing. He always makes sure everyone clearly understands everything he is talking about. There are small quizzes every week but they are completely based on homework. Actually, every test is based on homework, including midterms and the final exam. I would love to take some other class with him again!
Professor Dudum makes math engaging. He's patient, explains concepts clearly, and provides helpful exam breakdowns. I found Unstuck study a great supplement for study prep. Definitely take him if you can!
Tons of homework and doesn't count them for grades. Doesn't answer emails, and doesn't go homework questions. Claims the quizzes he gives weekly are like the homework he assigns, don't believe it. Make sure to follow his method or you will be marked down. By the end of the semester 1/4 of students dropped. Good luck!
I took him in the spring of 2025, and the class itself was very well-organized. The class is manageable if you put the time and effort into his homework. His quizzes and tests are similar to his homework problems, so as long as you master the homework, you'll do fine on his exams.
Isam Dudum is one of the best Calc 1 teachers at CCSF. The class is straightforward, and if you do the homework, getting a good grade is easy. There are weekly quizzes and three exams. I wish he taught Calc 2 or 3 because I'd take him again. He's also a very fair and easy grader.
Take this professor if u actually want to learn calc. If u pay attention, the material is extremely easy to understand. Homework usually took several hours, so give urself enough time. HW is optional and not graded, but the quiz questions are usually based on the easy HW problems, never the hard ones. Weekly quizzes and 2-3 chapter exams.
Isam Dudum's Calc 1 class was excellent. His lectures were clear, well-paced, and focused on true understanding rather than busywork. There were no homework grades, only quizzes and open-notes tests, which reduced stress and rewarded preparation. Fair, engaging, and very effective.
If you think Messi or Ronaldo is the GOAT, you haven't met Isam Dudam yet. He's an amazing teacher and, honestly, the best professor I've ever had.
Prof Dudum is by far the best math prof i've ever had! He's extremely clear about what goes on the exams, detailing exact sections, topics, and # of questions. He has weekly hw quizzes, but they're almost exactly like the hw so just do what he assigns. He's understanding when grading quizzes/exams as they are the only thing going into the grade.
Prof. Dudum is amazing. I was initially worried for this class as math isn't my strongest subject, but rly as long as u show up and pay attention in his class, u'll pass. His lectures r rly clear and easy to understand. He also has rly good handwriting, which imo, makes his lessons even easier to follow along. Wish he taught calc 2 for spring.
