The class was disorganized - assignments didn't get graded for a long time, etc. - but it was also fun.

The lectures were good, and the professor himself was great - funny, quite good at explaining concepts, and eager for class participation. The class was rather easy for the first half, and then more difficult for the second half. I found complaints about a disorganized class to be exaggerated.

Sheldon is a pretty amazing professor. He obviously really loves his subject matter and makes it fun to learn Computer Science. It was unfortunately a bit disorganized and our projects took ages to be returned. To be fair, it was his first semester at tufts: I have faith that he will be more organized in the future.

His excitement for the material and comp sci in general made being in class really engaging, so much so that now I'm a comp sci major. I do think organization and the order in which things were taught could be improved, but seeing how comp11 is going this semester, it seems he was aware of this as well and is correcting it.

Excellent lecturer. Comp 40 is a difficult class. He did a great job explaining hard concepts.

He's easily the most enthusiastic lecturer I've had at Tufts. Takes the material and explains it really clearly. His grading is extremely fair and you can tell he has a ton of hands on and real life experience with the subject. It was only his first year and he was my favorite Fall semester lecturer.

Does an awesome job with a difficult class. His lectures can be a little bit confusing, but he's always more than willing to clarify when you ask questions.

Class is completely unrelated to projects but still interesting if you can pay attention. Sheldon does a really great job with such a difficult class. Only downside is that he didn't design the class so he doesn't have a firm understanding of the projects. Use the TA's.

Sheldon is a ROCKSTAR! I absolutely adored this class. He's totally hysterical and a phenomenal teacher. The class is easy at the beginning and pretty difficult by the end. As far as I'm concerned, everyone at Tufts should take COMP 11 with Sheldon

Sheldon is a great CompSci professor, and an asset to the department. He is very good at explaining things to beginners.

He provides a great foundation from which you can learn more about CS. His assignments challenge students, ultimately creating an excellent learning experience. Plenty of help is provided through him personally as well as through TAs, but only if you ask for it.

Great teacher, inspired me to become a comp sci major!

Sheldon can either be really entertaining in lecture, or it can painfully difficult to stay awake. Comp 11 is undoubtedly a hard course, but the TAs in Halligan made it ten times easier - take advantage of them!

Computer science is not exactly the best subject to learn by listening to a lecture, so I'm not sure if it was his fault that I didn't really like lecture. It's better to learn comp11 by just doing the projects. Mark is still a great guy though. He's very helpful and in the end I learned a lot in this class.

Mark is super enthusiastic and hilarious. He inspired me to major in Comp Sci.

Awesome guy

Honestly, I didn't enjoy his lectures. I fell asleep in the middle of class, everybody left, and another class began and I was still sleeping. He is rigid in his grading/with accepting feedback. The course could have been managed more efficiently. He is affable outside of class. (Ooh by the way, he is an excellent ballroom dancer)

Really cool professor, teaches the material really well. Not for those expecting CS professors to hand feed them everything they'll need for projects or hw. He teaches the concepts really well, but expects you to be able to learn a lot of the syntax from the many online resources.

Sheldon gets a lot of criticism on here, and I don't think he deserves it. The class itself (comp40) has a lot of problems, but he does his best, and he is ALWAYS available to talk if you need to. Also, he's the only teacher I've ever had who didn't make me feel like a burden or like I'm dumb for being special needs. He wants to help, talk to him!

Mark is great. He's one of the funniest professors I've had and he teaches pretty well. If you don't understand what he teaches in lecture, you'll know relearn it in lab. The topics aren't too hard and homeworks are fine as long as you don't procrastinate til the last day.

He is a great professor. Thanks to his class I chose to be a Computer Science major. You learn a lot. There are a lot of projects that take up a good amount of time, but through these you learn all the basics of programming. If you put in the effort, you will do well in the course. Highly recommend.

Professor Sheldon knows his stuff, and he's good at covering the data structures in-depth in interesting ways to help you remember. One thing, though, is that we tended to spend heavy amounts of time on some data structures, and much less on others. Labs are good and fair, and homeworks are phenomenally helpful for cementing knowledge.

Sheldon is overall a very caring professor. Many people struggle in this class, myself included, but once you decide to actually talk and get to know Mark, youll find that you will understand the material better. Attending lectures isnt all necessary, but the readings (Weiss) are helpful before doing any of the HWs. Use the course calendar.

I think people get frustrated with the class and Mark because they simply don't start the projects on time. He is pretty generous with his grades and you get a note sheet for exams, so you have the ability to write down pretty much everything you've learned.

Mark is a phenomenal professor. He's articulate, clear, knowledgeable and fun. His tests can be a little unclear and he can be a little disorganized, but if you're going into a class interested in learning the material there are few better professors.

Great person, fun lectures, loads of work.

I liked him but I can definitely see why some people wouldn't  he's very passionate about comp, but often goes on tangents (which are entertaining but not always related to that class). If you're love comp, you'll probably enjoy him if you enjoy laid back profs; if you're gonna take this class and never touch comp again, try someone else

Sheldon is a pretty good professor. He can be a bit vague and his hw specs can be a bit vague as well, but he lets you have a cheat sheet for exams and he is receptive during office hours. Comp15 has been pretty breezy this semester and I think it's because Sheldon gave me a good base in Comp11.

Really knowledgeable/passionate about cs. Uses analogies and examples to describe concepts, making it easier to understand.

There are a lot of bad reviews on here but I don't think they're deserved. Mark is the best CS professor I've had yet and really cares if you learn. Homeworks are definitely hard but doable and there is always help if you need it. Exams are also hard but never feel unfair. He is extremely passionate about CS and wants the students to be too.

Hilarious guy, loves teaching comp sci. Gets concepts across but the syntax for coding you have to figure out on your own. Homework is not hard as long as you can manage your time well. Expect to spend a few more hours than you initially think on homework.

One of the most caring and funny professors I have ever met (in my long years in school). Does everything he can to help students. I think he also influenced the TAs of this class to be super caring and attentive to students. Very fortunate to be in his class during a difficult time (quarantine).

I haven't taken the final yet but honestly Comp15 with Mark Sheldon has been for me infinitely less stressful than Comp11 was last semester. I personally had never coded before Comp11 and struggled so much back then but in Comp15 I felt the assignments were very reasonable, had enough time to do them and they always broke it down into stages.

Great professor who really cares about his students. He grades by quality instead of quantity, so be prepared to do a tough homework assignment every week (but just one). He is very accessible, with office hours open to everyone and a Piazza forum where he remains very active and answers student questions. Get's you into the loop.

The lectures can get pretty long-winded and boring when he's working through example problems. Homework puts a lot of emphasis on testing. For big projects you're forced to explain your plan to a TA, and the waiting lines for office hours can get super long. Sometimes you'll be waiting for hours.

Prof. Sheldon was great! He seems to really care about his students and made choices throughout the semester that benefitted us. His lecture videos were very useful imo, and he had a strong and active presence on Piazza. He and the TAs were really on top of your understanding if you reached out and asked. Would definitely take another class!

Has a lot of jokes, so that always lightens up the lectures. If you are a first-time programmer, be prepared to put in the work. I highly recommend going to office hours--the TA's are super helpful.

Mark makes CS lectures about as fun as they possible can be. He is funny, entertaining, and explains the concepts clearly.

Very energetic and passionate about the subject, he makes the lectures engaging and allows you to really love CS. Sometimes the material and work load can seem daunting and overwhelming, but many office hours to help out.

Shark Meldon is a good lecturer and keeps things very light and enjoyable. CS11 is very difficult but I found the days in which he lectured were the days in which I learned the most.

Honestly don't know why he's getting so much hate. Yes, CS 11 is tough but DO NOT expect to be held by the hand the entire way! Make sure to get help when you need it. Mark provides so many resources and opportunities to ask questions both during and after class.

He was a really helpful professor, and a great lecturer.

Shark Meldon gave very engaging and amusing lectures about computer science. He also made a tremendous effort to help students outside of class through the help of TAs and Piazza *with which he is very vigilant and helpful*. The homework was challenging at times, but greatly reinforced the material and was genuinely cool by the end of the course.

I came into the class an English major wanting to clear my math requirement, and came out of it a compsci major. I really enjoyed the lectures in this class and appreciated Prof Sheldon's enthusiasm and sense of humor. Definitely get ready to spend anywhere from 3-7 hours on assignments. Start hw early! There's a reason there is one per week.

Good professor. I took CS11 with him (~300 students across 2 lectures). He's a clear lecturer and pretty funny. Review of CS11: 5/5 I'd never coded before but found it very manageable. Super organized for an intro class. Office hours are so plentiful and helpful. Lectures are good but most of the learning happens in lab and on homeworks.

His lectures were funny but I found them a bit unclear and unengaging. The structure of this class seems to make it hard to reach out and you learn more from TAs.

Shark Meldon is an amazing professor and I had so much fun in his class. He is super engaging and loves questions! The class is also what you make of it, aka he's as engaging as you are engaged! Definitely taking another class with him in the future.

Mark is a genuinely nice guy who really enjoys teaching. I would definitely recommend taking CS40 with him. He is always quick to respond with any questions outside of class. It's a very intensive class, but well worth it with the knowledge learned.

Very engaging lecturer, lecture content not too rigorous, gets off topic sometimes. Tests not too difficult, homeworks are very difficult but lots of resources (especially TA office hours) provided.

Average lecturer. Cool guy, taught 40, no complaints with him specifically. Course itself is time intensive as everybody says, but not that difficult if you go seek help (office hours, etc.)

Mark is very enthusiastic and friendly. His lectures can be hard to follow and sometimes he teaches things in a weird order but overall he is a good teacher.

Mark is a great guy and he and his army of TA's run an amazing course. Go to lecture, Mark's nerdiness for low-level programming is infectious. Ask questions, he often gives very good answers. Most of all, get ready for an average of 30-40 hours a week designing and coding. GO TO OFFICE HOURS or you'll suffer horribly (unless you're a savant).

Mark is a passionate professor and one of the kindest people in the CS department. He knows a ton about the course material. Mark sometimes goes on tangents which were a little confusing when I was in 11 with him, but were interesting in 40. Exams can be difficult but fair, especially if you go to the review sessions and make a reference sheet.

Yeah, CS40 is CS40. Its just as hard as everyone tells you it is. Expect this class to dominate your life and end your social life. But, this isn't Mark's fault. He is very passionate about the class and made it as enjoyable as possible. He was also very available, and office hours were super helpful.

Great professor. Take the course!

Professor Sheldon is a fantastic lecturer who knows just how to explain things in an accessible way for students seeing material for the first time while simultaneously offering optional insights into more advanced material. He cares about students, which is needed given the nature of the course which seems structured to tear them down

Funny and super caring professor. Honestly more engaging than I was expecting, he keeps you engaged and makes some jokes and is super accessible. Rough class obviously, but ended up enjoying learning the stuff a lot !

CS 40 is never an easy class, but Mark makes it fun and makes it seem like he genuinely cares for his students. He was communicative and pretty awesome - it's really just the projects that take up a lot of time. His lectures were always fun and worth going to.

One of my favorite professors of all time. Take a class with him (especially if it is CS21)! For CS21 (Concurrent Programming), there was a considerable amount of work: 5 homework assignments in the beginning of the course, bi-weekly puzzles in the middle, and a project in the end. Tough, but very rewarding. Take the class.

Clearly very passionate about the material and he does a great job of explaining everything starting small then scaling up to more complex problems.

Great professor, generous grader. Just wish the course could cover more content, and I think it's necessary to include more hands-on practice.

Professor Sheldon keeps the lectures engaging despite the challenging material. The workload is heavy, but Unstuck ai and the optional review sessions helped me stay on top of it.

Overall good class. Sheldon is a nice guy and does his best to make class a welcoming environment even if his jokes don't always land. He at times goes off topic and yes CS15 is not an easy class (its not meant to be), but if I had the choice to go back and take it again I would.

He's great at responding to piazza posts considering the class size. He explains complexity math well and why it's relevant for job interviews, performance time, etc. I personally think he's hilarious. Assignments for CS15 were definitely not as fun as CS11, but that's just a side effect of harder material. Exams were very reasonable.

Cs40 is crazy hard, but its not his fault. He's nice enough, but the lectures are very, very boring. Try to stay awake though because the content is relevant for exams. Go to office hours for the homework, or you are screwed. Be prepared to have very little social life this semester.

Mark gets too much hate. I also had him for 15 and he is so much better in 40. He is so incredibly smart and you will learn so much. Though his lectures can drag slightly, he is so incredibly passionate. The course is extremely difficult but that is intensional. I highly recommend his course especially if he is teaching with Noah. JUSTICE FOR MARK!

Cool dude w/ good lectures.

CS40 is a hard class, especially if you've only taken 11 and 15. The material isn't crazy hard but it's a LOT of a time. As hard as the class is, I think it's really worth it. Take this in a light semester! Mark is really nice and loves to talk CS. He has great stories linking the content to real life. Definitely go to OH. The TAs are great!
