Very solid, approachable teacher. Is clear in what he expects for the class, has a knowledge and a passion, a nerdy sense of humor to keep you awake in lectures.

Fundies is not easy but Lerner is a very good teacher. The tests (second one in particular) are notoriously tough but everything you need to do well is taught. Lerner is a complete nerd (in a good way) and is guaranteed to make you laugh. When he talks about something he's passionate about (languages/compilers) he is at his best.

Cool guy

Lerner is engaging, entertaining and a great teacher. He was fun, but definitely tried to challenge the class (beware his evil smile). I learned a ton in his class, I would take a class with him again.

Took the honors section of CS2500. Very good at lecturing. Really cares about his students. Lerner demands the best out of everyone, and gives notoriously difficult assignments and tests, but most of the time, everything works out in the end.

Lerner makes you work for every point you get, but that's why he's such a great prof. Never unfair, but not going to give away any answers. If he's the one who wrote a test you're going to take, go in expecting to spend the full exam time trying to think through it. If you can handle a hard class, can't recommend highly enough.

Lerner is an excellent lecturer. He is super sassy and doesn't let students get away with thinking they know more than they do. With a department wide curriculum his students are more prepared for each exam than students in the other sections. While attendance isn't technically mandatory you will not do well if you miss his lectures.

Great Professor! Funny and Enthusiasm!

The lectures were very helpful. He did not make it seem like he was regurgitating the textbook and class was enjoyable to attend. The homework was hard to keep up with it and the course load is a lot but that is how the course is, not his choice

I had Ben as a professor three times, CS2500, 2510, and 3500. He will make you work for your grade, the homeworks are time consuming and the exams are really tough (but they are usually curved). His lectures are clear and entertaining, and he always allows students to ask questions and will go over again. He is by far the best professor I've had.

Ben Lerner is the best professor in the world. He was just voted the best professor in the College of Computer Science and one of the two best professors in the university. Everyone loves his classes, you know the minute you hear him speak he is pure genius, and he is a living legend.

Benjamin Lerner truly is one of the best professors at Northeastern University. He is able to command his lectures masterfully and with ease. If you are able to have "The Blern" as a professor, consider yourself blessed. He is the elite among the elite.

Great professor, course has a lot of kinks still

He's a Lord, we call him Lord BSL almighty. Brilliant guy and great lecturer! He's one of those rare gems of a professor -- he cares about inspiring his students and instilling in them a passion for computer science. Students often catch him at office hours sticking around to help.

Basically the Yoda of CCIS

Ben is really good at public speaking. He has a great depth of knowledge in his subject area and is very encouraging of questions and discussion.

You cannot go wrong with taking a class with Lerner. The course is tough as hell, but it's the same across all CS2510 teachers, so you might as well pick the best lecturer.

Lerner is a great teacher: very knowledgable, cares about students, always available for extra help. Plus, he's a grade-A meme.

Amazing at teaching. He can explain virtually anything clearly and masterfully. He is by far the best CS professor I have ever had. However, he is a bit of a tough grader. In fundies, if you don't speak up enough in class (even in the bloated hundred-person CS classes) you *will* lose a fair amount of points.

classwork is hard, and ben is definitely a no-nonsense teacher. I am definitely a bit scared of him, but I learned a ton from his class, and enjoyed it immensely.

Blerner (as he is called by many students and faculty) is a great teacher. But he is not an easy teacher... at all. He will push you to your limits in his classes, and he will make you have a hell of a time. But if you make it out okay on the other side (and keep your GPA intact), you certainly will have learned a lot.

This course was the most Id ever worked on a single class until I took his 2510 course. You will learn a TON. The homework is an incredible way to practice/learn the concepts taught in class. There. Is. So. Much. Homework. So much. I cant stress that enough. However the learning you will have gotten at the end is unmatched to the other professors.

Great lecturer, learned a lot in his class. Would recommend it to anyone to take his class.

Never met a professor who cared about his students as much. He sees it as his life aspiration to instill good software engineering values to his students. 100% take his class if given a chance. If you hate him, that means you don't understand him and you're not motivated.

I hated Ben Lerner for the beginning of the course. If you are lost and aren't putting in the time out of class his opinionated attitude adds to the disdain of the course. OOD is hard and labor intensive. His lectures explain concepts profoundly better than anyone else. His office hours are even better. Start early, get help and take Ben Lerner

Benjamin Lerner is an exceptional lecturer who shows enthusiasm for teaching and engages students in the course. Despite occasional condescension, particularly on Piazza, his snarky comments often respond to questions that are redundant or already addressed in online material. Work hard and come to class prepared and it will be an amazing class.

Prof Lerner is by far the best and most challenging professor I've had at NEU. His lectures are phenomenal and you will learn a lot if you put the effort in. He and the TAs are very accessible outside of class - go to OH they are so useful for the homework. There is a TON of homework but they really help to enforce the lecture content.

Ben Lerner is one of the best lecturers I have had so far. If you want a great experience in a computer science class, take his section. The class is definitely difficult and has plenty of work, but you will come out of it a better programmer and with far more knowledge

The coursework for this class is the same no matter which professor you take. So no matter what it is hard, hope for a good lab partner. Dr. Lerner has a distinct teaching style, which is why he's so polarizing. He likes to write in chalk so he can explain concepts through diagrams. Once you accept that he knows what he's doing, you'll learn.

Very fun and easy class! Please take :3

A trend on RMP for Blerner's is that it will increase when he teaches a semester of Fundies 2 Accel, and go down when he teaches OOD, and I do think that says a lot about the people that enjoy taking his class. If you genuinely enjoy learning about design and being challenged by the coursework, take his class, he gives great lectures.

Professor, a programming whiz, a true philosopher. Why give a straight answer when you can respond with a cryptic question? It's like a game of intellectual ping-pong, except you're playing with a wall. He ensures you leave the conversation just as confused, if not more, than when you entered it. A true gem in the academic world! Love Him!

Even during the lecture, Professor Lerner mentioned that the class is supposed to be a weed out class, but regardless, they give you the resources you genuinely need to pass the class. If you go to most lectures and labs, you will do pretty well in the class. It takes a lot of commitment and dedication; you may regret your major, but it's possible!

Lerner genuinely wants you to do good. When many students were failing, he was willing to add more weight to EC assignments. He stays after class to answer students' questions. He's responsive to emails, Piazza questions, and is willing to meet beyond his OH to help you. You just have to put the effort. He has inspired me a lot.

All the negative comments are because his class is hard. He is the best teacher/lecturer I've had, he just teaches a hard class so people blame it on him. He embodies the a Bostonian in the sense that he's kind but not nice - he genuinely wants you to learn and do well and cares about you and if you can see past his tone, you realize he's great.

He made every sweater he wears... honestly impressive.

Really easy class, you will find it interesting and enjoyable!!!

Ben is a great professor who will challenge you to think more in-depth about what you are coding, thinking about more than what it does. He is challenging and knows a lot about the subject he teaches. If you want to get the best understanding you can get out of the course, then he is the professor.

Tough class with rigorous expectations, but he was 100% consistent with what he expected. Very friendly in office hours and responded to questions well. Can be kind of sassy on Piazza with questions he thinks are stupid, but if you lean into his coding/teaching philosophy you will learn a lot and become much better at coding.

Great lecturer. Even though I'm taking CS 2510, he tries to incorporate good object-oriented concepts from the get go. Class is usually very interactive with fun lectures. The Accelerated version can be very heavy in terms of homework load. Usually accessible outside of class.

Professor Lerner is an excellent teacher. He has a lot of practical experience working on compilers and is extremely knowledgeable on the subject. He shares lots of anecdotes from his own work and is very responsive and encouraging of questions. The work is challenging but very rewarding and very practical.

I enjoyed his lectures. He can be pretentious at times (and sometimes talks down to people) which is nothing out of the ordinary for academia. I thought that his lectures were good and useful to attend, they seemed to track the homeworks closely. The labs were fairly removed from the lectures and felt similar to the exams. attend attend attend

Ok, listen up. This class will be the hardest of your entire life. Let that sink in. Lerner is one of the smartest teachers I have ever had. He also the most condescending. But he wants his students to succeed. Start assignments the DAY THEY ARE RELEASED. Do NOT procrastinate or you will FAIL. Attend lectures, ask questions, you'll do fine.

Prof. Lerner is easily the single best CS professor at Northeastern I've had so far. His classes are hard, and will very likely be the hardest class you'll take that semester - but hard doesn't mean bad. You learn A LOT more than the same class with other instructors, and he is extremely clear about what's expected. He's also very fun in class.

His homework and exams can get tough but he is very knowledgable and have very interesting lectures. You'll definitely learn a lot.

Professor Lerner is a great lecturer and knows how to teach his students. Not only is he extremely knowledgeable, but he also makes sure that you are a better coder after taking his course. His assignments are difficult, but they definitely force you to become a better programmer.

understands the motivation behind the curriculum and how to demonstrate strong pedagogy in his teaching -- i'm fundamentally a better developer because of my experience in his courses

He teaches very, very well. If you want to get something meaningful out of the course, then take his section of the course, listen intently to the lectures, and ask him any questions that you may have.

I liked his assignments. I learned a lot from the homework, despite the fact that a few took me 15+ hours to complete.

A really great lecturer who has passion for what he teaches and brings a strong desire to see his students not only succeed, but find their own love for the subject.

Lectures were reasonably paced, and if you miss something its on the course page. I wrote the bare minimum tests for examplar, and self-evals suffered for it. Assignments were reasonable, and follow-up assignments were quick if your code was written well. And don't forget to make a design decision and document it.

Prof. Lerner is a truly special teaching professor. His lectures are very well thought-out, and he seeks to motivate each new topic introduced in a way that makes it feel as if you could have come up with it yourself. He is readily available outside of class, and always willing to help when you need it.

Took the accelerated section with him. Tough grader, but really pushes his students to become better programmers. His lectures and materials really shows that he cares about what he's teaching.

Great professor! He is very knowledgeable and excellent at communicating the intuition and basis for difficult concepts! He does expect students to put in a lot of effort, but IMO it is worth it

I took the accelerated section and learned a lot in this class! If you have either a good amount of programming experience or the desire to be challenged I really recommend taking this course. Wasn't easy or anything, but wasn't irrationally difficult. Helpful TAs and the one time I went to his office hours he was extremely friendly and helpful.

Best prof ever hands down

Hardest class I've ever taken. But best prof ever
