She explains things well and is very helpful if you try. Attend classes, otherwise you will be lost on exams.

She was a Data Structures TA and did well with what she was given. The professors posted incorrect code, poor examples, length and unclear assignments, and she was sort of the messenger for it all. The professors needed work but as a TA she was kind and helpful. She was very available and made the best of a sticky situation with bad professors.

Joanna was a TA for this class and tried to make it work while the professors were a mess. She really helped out making the class easier to understand. She would always make her self available for help and would try to assist in every way possible while the professors were mostly useless. She is willing to work with you and help you out.

One of the best professors I have ever had at NYU. Clear, concise, and always very well prepared for lectures. Posts notes on every lecture, encourages participation. Very approachable and gives extremely fair exams. Definitely recommend.

I took Joanna for C++ back in 2011 at Hunter. She will definitely work you but it will pay off in the long run. Get ready to program at least 30+ hours a week. She goes out of her way to help her students. She provides additionalsupplemental resources to help you understand the content as much as possible. No slacking allowed in her class.

The class is hard. She makes herself very available to answer questions, but by no means will she ever give you answers. She'll make you work for everything and it's draining but so much better in the long run. I finally feel challenged for once at NYU, like I'm getting my money's worth. Be ready for hours++ of work per week though!

She's funny and makes the subject engaging!

She's a friendly and nice person, and is very helpful and understanding during office hours. Lectures are pretty boring. Her class is hard but she does her best to ensure the success of all of her students. Projects are extremely comprehensive so you spend a lot of time on them but still learn a lot. If you take her class, you better love Java.

She is a helpful professor. The programming projects are a little bit tough if you pursue extra credits. The homework is manageable. If you want to get a high grade, read her lecture notes and complete all of homework.

Joanna is by far one of the best Computer Science teachers I've had. Her notes are clear and she provides source code for every problem. Exams are really straightforward they test whether or not you've done the homework on your own. If you listen in class you will do well.

I had Professor Klukowska at NYU this semester, as a freshman. Her class was a perfect introduction to Java and Computer Science, and I'm so glad to have her again in the Spring for Data Structures! Her class isn't easy but it's so worth it once you have those "ooooh!! OOH!!" moments. She's always available and there for her students. 1010.

She is really nice and always there to help. Just do not be afraid to ask questions and work enough to get an A

She really goes into the algorithms of how things work and is big on visuals. Not much coding in class, and even then it is pseudocode. She cares more about your understanding. Projects are tough though and they come back-to-back, so be prepared to think and design your programs. Homeworks are not graded but prepare you for quizzes/tests

I took the class before this in the curriculum with a very easy professor that made me think I was a coding genius, put Professor Klukowska kicked me into reality. She is really one of the best professors I've ever had, and I've learned more from her in 2 months of this class than in any class I've taken before. Take her take her take her!

Her projects are one of the simplest compared with other professors since all you need to do is implement classes and not start everything from scratch. Her tests, though, are difficult

Super easy A, definitely take her. Jokes aside, easy A if you actually study the lecture notes and do the practice questions from the book.

Joanna is so solid. Her accent is both understandable and enjoyable (Polish-like tendencies) so I recommend lectures in a major way. I'm not gonna lie, this professor is gonna grade you. Her pen is a weapon and you have to battle it. Buy the book fam, save laundry quarters for a couple months or something, I don't know your life, but it's worth it

I had Joanna for 102 as well and honestly I think it was a joke compared to 201. 201 lectures are just way more rushed and difficult to digest. Also, pop quizzes are weighed pretty heavily (almost 10%) despite them being quite luck based (there were only 3 of them and who the hell can always be caught up in a class like 201). She's helpful tho.

If you're serious about Data Structures and really want to learn about it, take Joanna's class! She makes you learn more about knowing an algorithm rather than memorizing the code. She can be challenging, but she is one of the best teachers you will ever have. Her office hours are extremely helpful too.

Joanna is a fantastic lecturer, extremely organized, and very helpful. She gives so many helpful resources and they are all extremely clear and concise. Read everything she posts! I will say, even though this is true for every CS teacher I've had, I wish she / the graders gave the assignments back earlier so you can get feedback quicker.

An excellent lecturer, makes classes interactive and remembers the names of her students. Does pop quizzes if she sees attendance drop. Her exams are long, but she's up front about the material on it. She loves to assign stuff, so don't wait until the last minute to start something. She's worth the effort, though.

One of my favorite professors at NYU! I had her for CSCI 201 Systems Organization, and let me tell you: that class is HARD. Despite that, she did an amazing job being thorough with the material, and is a professor that I genuinely like to go to her lectures. TAKE HER 500% if you have a choice between her and anyone else for either 201 or 102!

She's highly recommended and now that I took her Data Structures class I know why! You will learn AND work hard. I recommend forming a study group in the class for studying purposes. There is no group work except in recitations. She only teaches CSO in the Spring semester. Most of the grade (65%) is only the midterm and final. She doesn't curve.

I honestly didn't think that she was too difficult as a professor, exam average is 80. She is very fair. Take the time to review the material on your own time and it won't be too bad. Make sure you're very thorough and efficient in all of your projects from the start because everyone gets wrecked on the first one.

Go to class and take notes, you will learn so much and she explains things clearly and in depth. Adhere to her spec for projects or your grade will be wrecked; if things are not clear, ASK questions. Her exams are super fair, make sure you understand concepts and do not rely on solely memorizing code.

Joanna is a solid professor. Even though she's a pretty tough grader, her expectations are really clear. Projects can be long but she teaches very clearly so that you know how to apply the data structures in the projects. TL;DR - she's tough but you learn a lot.

Clear teaching, and manages the class well. You need to review the material on your own time, and that's not a bad reflection on her -- computer programming is hard. She is good at adjusting the pace of the course according to the students' progress. Overall good experience.

Joanna has very clear explanations, but the project requirements are pretty hard. Might get overwhelmed at first, but read the notes and the book materials and there's nothing too harsh.

One of the best CS professors I've had. She's hilarious and ruthless at the same time(!) but do not fret, she's doing it so that you learn. The way she describes different data structures / visualizes it on the board is super helpful, not to mention she gives out mock interview questions. Tough grader, but she'll make you work and learn.

Best professor ever, I took her 8am recitation this semester just so I could study with Joanna again. Her material is hard, but so is CS, and she is a very clear, straightforward professor.

I have to say she's the best cs professor ever. She explains everything super clear and knows the class material very well. I took both Data Structure and CSO with her. I learnt a lot. However, you need to spend a great amount time and effort on her classes; otherwise, you might get a really poor grade. (Average of CSO midterm is always around 60)

Very difficult to get an A. Great lectures, test heavy, pop quizzez.. take Bari if you can hes more chill. Shes a solid choice otherwise.

Although Joanna is a relatively tough grader, you will ultimately get a higher grade with her than with another professor (e.g. Bari). Amazing teacher, she even takes questions from real CS interviews. One of the questions discussed in class was the exact same question I was asked in my internship interview. Personally got an A-, highly recommend.

best comp sci teacher

super great lectures, learned so much from her, would highly recommend. do as she says and you'll do great.

I adore Joanna. Took her for DS, and even took 8am just to get her again for CSO. Her lecture explanations are always crystal clear (go to them!). Start the projects early and they are no problem, spec is detailed on expectations (plus she is very active on Piazza). Tests are super fair, never any surprises - but they will test you thoroughly.

I love Joanna. I have had the greatest computer science experience with her in Data Structures, and highly recommend for everyone to take her.

Informative lectures with clear slideshow slides. She's extremely helpful during recitation and office hours. Loves to answer questions. You absolutely have to read the book and do the practice problems, but the hw/recitations/lectures complement the book and Joanna will help you when you're confused. Take this class; it's incredible!

Very sleep inducing lectures but informative! The midterm was pretty easy and covered what we learned in class. Her projects have very clear instructions and are doable.

I mean will I fail the final? Probably. Did I learn a lot over the course of the semester? Certainly. She has a unique personality thats not meant for everyone, be ready to take a joke. But theres no doubt shes incredibly smart at what she teaches.

the material can be challenging at times but joanna is one of the best professors ive had at nyu. She really tries to impart her knowledge of the subject on each of her students with great lectures and is always open for consultation during office hours. she can be a stickler with grades however but she is a fair grader through and through.

Joanna is, hands down, the best professor Ive had in the CS department. She is passionate about her work and the students learning. However, if youre looking for an easy A or looking to coast through this major, do not take this course. The work is hard, she is a tough grader, but you will walk away having learned a lot.

Joanna's class is quite challenging, but her lectures are extremely informative and she's actually super nice and helpful in-office hours. She won't give answers during OH, but she'll lead you down the right train of thought. I highly recommend her class! Probably the best DS prof there is at NYU!

Joanna's a really solid professor, and she really tries to make you understand each data structure. The grade heavily depends on the 6-7 projects that have to be completed throughout the semester, and each takes a lot of time. She's difficult but I think she prepares people for interviews very well. USE HER OFFICE HOURS

If you get the chance to, absolutely take Joanna at least once during your CS degree. Her projects and recitation activities are difficult but really encourage full comprehension of the material. Skip lecture at your own risk, every lesson by her is extremely useful and detailed, but if you do need extra help, she is very friendly at office hours

Partly overlapped with CS 310 Basic Algorithm. Not difficult as long as studied well in Basic Algorithm course. Moderate (a little bit heavy) homework. Lectures are easy to follow up

Not difficult but you don't know how it will be graded. Need to spend time to get an A. But easy to get an A- or B+

Joanna is tough and grades harshly, but her lectures are very clear and interesting, and she's a really nice person and easy to talk to in office hours. If you try you will come out of the class knowing a lot about computer systems. Her grade cutoffs were harsh (95 for an A) but luckily she was nice and curved it.

Professor Klukowska is great at lecturing. She gives clear explanations of the course material and takes time in lecture to answer questions students may have. That said, I cannot emphasize the hard work that one must put in for CSO. Review the slides plenty and consistently, attend 90% of lectures, and do the textbook practice problems.

Joanna is a super caring CS professor. She's willing to sit with her students and give them her full attention at all times. Lectures go a bit fast- don't fall behind on the material. Only one midterm and final is heavily weighted. Everyone hates CSO but I would recommend taking with Joanna because she'll help you out if she sees you care.

Professor Klukowska is a TOUGH grader,. She gives HARD tests (but they are not horribly difficult). BUT, you will learn a lot from the projects and readings she assigned. She is always willing to help during her officer hour and in a platform where she organizes all her students' questions.

At the time that I took Prof. Klukowska's class, I did not enjoy it. CS201 was too dry and backend for me. But now looking back, she has always been extremely prepared and helpful. There would be a lot of work, but the work was necessary for any CS majors though unpleasant. Overall, a very straightforward and serious professor who wishes you well.

Spr 2020. It's not her, it's CSO that's hell. Material seems ok when heard in lectures, but much harder to perform in exams. Only one midterm and a big final. Homework are manageable and useful. Teaches you how to use git well, and this knowledge will be useful for the rest of your time in CS.

Great professor to have if you actually want to learn a lot. HOWEVER... her projects and quizzes are hard. We actually need to learn the materials. The professor is supper accessible during office hours.

Joanna is a great teacher, who is super accessible outside of class and really makes sure you know algorithms by the end of the course. Weekly problem sets make up the bulk of your grade, & by the end you really know how to program- great problems for interviews, hackerRank, etc. Joanna really cares ! She's tough but you learn soooo much

At first, I truly hated this class. The quizzes and exams seemed to be filled with tricky questions. However, once you get used to her testing style, the class is great. She is a good lecturer, and she is great at helping out students... if you make sure to tell her you are struggling. Her projects are time intensive, but a great way to learn!

Participation's not mandatory. There are pop quizzes that can be made up easily by writing lecture summary. Exams and quizzes are not easy. They are largely based on the lecture slides, but if you understand everything on the slides, it should be good. Prof said she won't curve, but she ending up doing huge adjustments, pushing everyone's grade up.

Sometimes the quizzes/tests get stressful but she's really knowledgeable and good at explaining things.

the GOAT

Class isn't easy but you really learn. She cares a lot about the subject. Reminds you why the subjects are worth learning about

joanna is a good professor. projects get difficult by end of the year so make sure you start them early. quizzes and tests were harder than the projects for me personally. no curve.

Regardless of my grade, I can say prof K's lectures are very well organized, insightful and she's always willing to help, only if you ask her first. If you want to learn, take her class. If you are just looking to get through data structures with a good grade, take another prof. Would be very helpful the sooner you get used to her testing style.

Prof Klukowska is the most serious prof ever. I recall her laughing only 4 times that semester(spoiler): 1. 8 rabbit=rabyte 2. Little vs Big Endian 3&4. Mock at others and me kindly for being dumb. She is very caring and answers all of your question, but she likely won't make you love CS. She is most helpful if you are already interested in CS.

Took Joanna last semester, out of 5 CS professors I have encountered thus far, she is the best one if you want to learn. I think she delivers material very well and is very engaging, the stuff she explained really stuck with me. Her quizzes are tricky though, a couple of missed questions and you're getting C, but she did have a curve at the end.

People are too harsh. Projects are difficult, but they prepare you to become a good programmer. I have cried over this class but everyone giving a bad review is bitter. I've learnt a lot and the projects are useful. Joanna is a very good lecturer. I'm a humanities major and not great at CS but have done well in the class. Quizzes aren't that hard.

Yeah the projects are hard but that's why programmers get paid a lot lol you can't get a job and cry about doing a big task or project. This class is NOT for the weak but Joanna will help you learn and get you HIRED. If you're not cut out for this workload, don't go into CS. Data structures are the foundation of CS and one day you will thank her.

Joanna's class develops a strong foundation in computer science that will help you with the rest of your computer science journey. Took this class 2 semesters ago, and I'll say this, if you ever want to work at FAANG or any other big tech/quant company: take Joanna's class and push your capabilities. Work in the present to succeed in the future.

Pay attention during lectures and properly spend time to understand the concepts and this class isn't as bad as everyone makes it seem like it is.

Thought I would get a awful grade since it is a tough course and I didn't take the prerequisite course Basic Algorithm, but her lecture is extremely inspiring and useful so I paid some effort and got back on track. I end up getting an A despite the fact that I gave up half of the points on a couple of homeworks and got a B for the midterm.

Professor is pretty good compared to other data structure professors. You really do learn a lot. The projects are not that hard, if you start them sooner, there is just a lot of test cases to complete, but there was only one truly hard project. If you put in the work for quizzes and projects, you can do well

Why is there so much negativity? She is a tough grader, but she is also one of the few well-organized professors in the computer science department who actively teaches. The level of difficulty in her homework is pretty reasonable (reasonably hard, but they would help you develop good coding habits like input and error handling)

A very challenging professor with difficult exams and long projects. Only take this class if you're serious about cs and actually wanna improve. Otherwise, take an easier professor.

Joanna is a nice person. She does give hard assignments but is very reasonable compared to other CS professors I had. She really does help you become a better coder and you really lot a lot of practical stuff. If you do all the work, you will succeed and get a good grade.

Her lectures is useful and help you build a solid foundation in CS. She makes difficult concepts become easy to understand and engaging. Very organized she is unlike other professors I had who were all over the place confusing students. Go to her office hours if can, the best help ever. She does curve the class if she sees students struggling.

Joanna is the best. SO MUCH HOMEWORK but she made me like cs with her creative project themes. Her lectures are so much easier to follow than other professors. She and the tutors have lots of office hours and she always cares to help students understand as much as possible. I've taken 5 profs. in the department and she has been the best so far.

Mental breakdown!!! But have to admit this professor teaches clearly.

Joanna's lectures really helps you understand. Event if I recieve a terrible final grade I will not regret taking her. Projects and quizes can be hard, but after completing them you do gain a deepr comprehension of data structure. If you want to be a good programmer and are heading towards CS major do take her, else take someoneelse for good grades

The class was hard but felt very fair and organized. Lectures were informative, and the class definitely made me a better programmer at the cost of my sanity. Projects were lengthy, and the last one took upwards of 25+ hours to finish. She's a good professor, but don't take her if you have other hard/time-consuming classes at the same time.

She really cares about her students and wants to see us succeed, often checking ed (the online discussion forum we used) late at night outside of school hours. Her lectures and projects are well structured and planned (start them early!) and I feel like my coding has improved immensely as a result of this course.

Most of the people who give her bad reviews don't show up to class then complains when they get a bad score. Data structures is a hard class and as long as you keep up with work and seek help via office hours or TA, Klukowska teaches the material better than any other professors.

Easily the most painless 8 am lecture I've had. The projects were a lot of work, and when she says you need to start early, you really do need to start early. But the lecture itself was always entertaining. Also attendance isn't "mandatory" but she'll randomly do a class poll that you have to be there to respond to and if you don't you lose points.

It seems like people either love her or they hate her. I absolutely love her teaching style, how she runs her class, and how she explains things. Clearly, many don't. My hypothesis is that this course is really good for people who get coding pretty intuitively (and actually show up to class); if you don't it goes a little fast.

Trust me. Take data structures with her and actually do the projects. I am a senior now, it helps your understanding so much more than other professors. She is not easy, but you should learn this stuff out of anything at NYU. Other professors later on are much worse.

Joanna is a very good lecturer and clearly understands the material she's covering, but I think in some ways she makes the class unnecessarily hard, like she definitely wants us to work for the grade. The slides are the best materials to use for review and for exams it's very important to know implementation of the various structures!

I think that she is a very good professor. She gets a bad rap on this website, but I think that's probably just coming from people who used the internet to cheat on the AP Java exam. I think if you know the basics of Java, and have some programming experience a good grade is easily accessible to you. Phenomenal lectures and a really fun class.

Very lenient grader. Homeworks were a little hard and long, but they build on top of each other so as long as you attend class, should be fine. SO ORGANIZED, had SUCH good notes, and CLEAR hw/exam instructions. I literally failed WAY below avg for the midterm but did well on hw assignments and decently on final so I passed the class with a B!!

Taking this class after 101 kinda gives you whiplash, but imo she was very fair with grading and assignments. It's a bit challenging to keep up every week with all the material (you need to review every week if you don't already have a solid foundation in java), but in the end, it made me a better programmer, so I think it's worth it to take her.

take her if you want to understand the material and actually learn. don't take her if you want an easy A! i feel that most people hate her bc of the workload, which is understandable bc she does give out lots of projects and also tazke home quizzes. Overall, i recommend her bc i learned a lot and she made the material easy to understand

I liked Klukowska. She has take home quizzes and more difficult projects than the other professors (lots of test cases). I thought that her midterm and final were really similar to the questions she asked for the pollev and the THQs. Definitely take advantage of the office hours and tutoring sessions, her class becomes a lot easier. Fair overall.

The course was not very difficult and people here that give her bad reviews simply do not attend lectures, i assume. projects can be very time consuming, but she gives you 7 extra days a semester and even a 5 hour buffer period for every project. overall a pretty decent professor

She is organized and gives really good lectures. The workload is high with a lot of projects. I would recommend her because her class helped me learn the content and become a good programmer. The only thing that bothers me is that she is too picky about the documentation. She would take points off even if you forgot to put your name in your code.

Klukowska's class can be challenging, but her teaching really helps you learn. Lots of projects, but the Unstuck ai app was a lifesaver for staying on top of it all. Definitely worth the effort if you want to become a strong programmer.

Joanna is a very organized and knowledgeable professor, but the class has a very harsh learning curve, so take it seriously. Attend both recitations and lectures, as they cover different material, and start projects very early so you have at least a full day to debug the excessive amount of test cases.

Joanna's APS class was definitely one of the most helpful CS courses I've taken at NYU. Joanna herself is hilarious and does a good job of explaining difficult concepts. My only complaint is that the second half of the course is basically just taught by the students, and I would've preferred to be taught by the professor herself.

Not bad. Data structures was fine as long as you know java. General advice, literally just go to class and go to recitation, and study. She gets a bad rep because 8 am, and a bunch of people don't show up to class and wonder why they fail the midterm.

Take her negative reviews with a grain of salt. All you really need to do is find some time to study and make sure you attend recitations and lectures. Almost everybody says they are a better programmer coming out of her class. As long as you know some Java and have some time to study, you'll be fine.

I really enjoyed Joanna's class. I took AP CSA two years before this class and still felt it was pretty doable. However, I did attend every single lecture and recitation and made sure I was caught up if I didn't understand anything. I got 100s and a 99 on the projects because of the amount of time I put into them. My advice would be start early.

Her test difficulties are very reasonable and her slideshows are very informative and useful for learning. Attendance is taken through in-class polls that happen every few sessions.

Great Lectures, projects are a little annoying, but tests were pretty straightforward. Overall very nice professor.

Joanna is the best professor of CS I have ever met! I learned plenty of things from her lectures. And during her group projects, we learned great presentation skills, and we learned more from peers apart from the slides provided by the professor. Really nice experience! Take her for SURE!!!!!

Don't take this class if you want an easy A, take this class if you actually want to come out of the other side with a strong proficiency in data structures. The projects are difficult, and the tests & quizzes are tough. Joanna doesn't pull her punches, but she genuinely cares about her students, so if you put in the effort, you will go far.

Not as bad as her reputation makes her out to be. Projects do take up a decent amount of time and the 4 quizzes are weighted pretty high for what they are. However, the midterm and final are very similar things that were done in classes and recitations. Attend every class, go to office hours when needed, and start projects early.

The projects that she gives illustrates Data Structure concepts well, and also gives ample amounts of practice for students to gain familiarity.

she's a 5 if you want to learn the material well and a 1 if you want to sleep through class. up to you but i know which one i prefer

Klukowska isn't bad -- she'll teach you the content just fine, though sometimes the lectures are a little monotonous. She's very sarcastic, and sometimes funny.

She is definitely a knowledgeable person and will help you a lot if you attend office hours. People who are complaining just don't want to try and get an easy grade, but I sure learned a lot from her. Pretty nice curve in the end so as long as you stay on top of everything you should be fine. Take her if you actually want to learn.
