He knows his stuff, so you will understand the material well and do good in the coourse

explains things very well, knows what he is talking about. talks pretty fast so u better keep up

Prof. Shell is what you call a teacher. He knows his stuff and brings it across to his students very well. I would recommend that anyone who hates math should take his class, you will find a new found love for math.

Very good, exams are ok.

he is a very great professor...best prof i had at ccny

i had him for 2 semesters. He's good, exams are somewhat ok, and very linear when correcting exams; take him and u'll get a good grade for the final. If u 2 minutes late for his class, u might not understand for the whole period, since he goes so fast.

he is very clear and explains the problesm properly. the tests are tricky as heck!FINAL WAS OVERKILL. homework is ok. overall: a great professor!

Prof shell is better than most math teachers at CCNY. Though he teaches fast, U get the point if U come to class well prepared. Exams are "standard" as he asks what U are supposed to know in his class. I ended up with an A- although with gruelling effort. I'll take him again anyday. Thumbs up Niel.

He goes fast but is very clear. His test are fair if you know your material. He is helpful and wants everyone to do well. He is a great overall prof.

Prof shell is not so bad.He's a good professor.I expected worst after reading his review but when i took him.I discovered he's great.May be boring in class but he gave most of the people in class a good grade and curves sometimes.He cares about his student so don't give up.He gave most of the students in class extra points.

I wish every professor in the CCNY math department was like him. This is not an easy class but he's here to help you. Bring your A game and you'll be rewarded.

One of the smartest math professors that I have encountered. He definitely knows his stuff very well. He is funny too. He explains and teaches very fast. His exams are fair. It gets a little hard. He grades generously as well. The dept. final is somewhat harder. The minor problem is that when he goes so fast, he makes careless errors. But take him.

This professor is exellent. He nows the stuff he is teaching, if you did not understand something he will gladly explain it in class. The lecture is straight forward and if you pay attention and take notes in should be a breeze for you. Although he may seem strict he is very friendly. Best math teacher ever!

he is excellent at teaching. nothing bad on him at all. i have no idea why people giving him such bad comment. i took 391 with him. he is funny and generous when it comes to grading. most of the time if you have small error errors on the test, he won't even take off points as soon as you understand the way to solve the problem. highly suggest him!!

He is a good professor. His exams are really fair. You must study from the textbook in order to pass them. He is also a fair grader. He speaks fast sometimes and you might miss some info but he is willing to go over what he covered. His exams prepares you for the final, so if you do well on his exams, you ace the final.

This class will be hard if you don't read prior to class. He teaches a bit fast but is willing to explain everything again. His finals are not easy since he asks you to prove a few concepts. You must know your math terminology well in order to get an A on his exams. He's a good prof. and a fair grader overall. Good exam grades = A on final.

Shell is a good professor and very helpful. he gives homework and goes over it in class, but doesn't check or grade it. CALCULUS IS A HARD CLASS, IF YOU DON'T DO HOMEWORK AND STUDY ON YOUR OWN TIME YOU WILL FAIL. He does go fast sometimes, but if you ask him to go over it again he will. If you don't ask questions he's going to assume you understood

Gives 4 exams(drops the lowest score) and a final. His exams are pretty much all of the examples he does in class and he does not put anything unexpected. Even though there's nothing that's unexpected you have to study hard to get a good grade.

Great prof. He just loves math and is very energetic when lecturing. Funny too. Possibly the smartest prof I've had, yet totally humble and understands how hard the material is to the students. Very willing to use his own time to help us and print useful stuff for us.

approach him after class or during office hours hes very helpful. Calc 3 has alot of material, seems he just wants to finish n doesnt check if students understand, trust me they dnt.hes lefty so he blocks the board, n towards the end of the semester hes pretty much at the board teaching himself the material n not the students.USE TXT-BOOK& Youtube

i took him for calculus 1 years ago, making it my second time taking calc1 since i failed before, and i failed this class too, making 2 failures. but again that was my fault for loly gagging too much. he is a boring prof but cares about his students. i actually learned from him even though i failed. im an A student(now) aceing calc2/3 etc

He is one of the best teachers I had. Very clear, goes over homeworks before the exams. Exams are very straight forward and the final is in the same manner. Highly Recommended!

nice guy, covers everything in class, does reviews before each exam. exams are easy,uses question similar to the ones from the book.Gives hint before the matlab exams.Tries to help in every way... even after class. Only problem i faced is he blocks the board since he is left handed,and some tiimes i didnt really understand what he was talking..

OMG One of my hardest semester, this guy rushes like hell. He is helpful outside the class but his exams always involve one tricky question which is 20% of the exam lol.. plus he doesn't curve. I wouldn't take him again. Good Luck !!!

I am writing this evaluation a while after I finish calc203 with professor shell. after 3 calc classes and two more advanced (391, 392) I am sure that he is the best Math professor at City College.

Professor Shell knows exactly what he is teaching. Math203 itself is a difficult class and by the time you reach this class, you'll know how to prepare for math classes. Just show up and be ready, he tends to go very fast and try to sit on the left side of class. Hard to see on the right. He is a great professor and he's always there to help

Nice guy, gives lots of partial credits on test. Study and you'll get good grade, be careful of the final though he doesn't write it and its a lot harder than his normal exams throughout the year.

In general, if you finished all the homework questions and understand them all, you will get a A+ for the exams. There will be 4 mid-term exams plus the final. He will drop the lowest grade for one of the mid-term exams. The average mid-term grades are around 85. He speaks very fast in class and LOTS of notes. He is very good professor for cal3.

He's a good professor, no doubt about that. My only problem is that he goes too fast, that's it. He's nice, understanding, helpful, and knows his stuff. His exams are a very similar to the homework problems. Do the homework and you won't have a problem. 4 exams, drops one, no quizzes and gives two questions for the matlab final.

A really nice guy but he likes to put questions from the final. Warns you what is on the exam, not the best ex plainer but no the worst math professor there. Overall, matlab test was super easy though, two questions from the previous things he taught.

One of the best professor's you can get. He talks pretty quickly, so you really need to pay attention to his lectures. Assignments aren't checked so you can basically do them whenever you want, and he goes over them a class or two before the exam. He has some occasional dry humor too. All in all a great prof and would take him again.

Great professor. Takes the time to stress certain key points that are fundamental in a specific topic. Also outlines common mistakes for students to avoid. Easy grader and will give plenty of partial credit (if deserved). Some complain he goes too fast but I think his pace is just fine.

He goes fast and lectures are long. But, if you pay attention you should at least get an A-. He's also a very nice guy and a generous grader.

Great professor. Go see him for extra help if you need to. His exams are fair. He grades them fairly and generously at times. If you focus on class examples and homework problems, then you should be fine.

Difficult material to start thinking in 3D, but he explains it very well and shows the proofs in detail. His tests are fair and he is generous with partial credit for algebra mistakes if your calculus is right. HW is not checked but it is reviewed in class and I recommend doing the assigned and then some to prepare for the tests. No curve.

Good professor. He goes SUPER quick however and teaches like he's on too much caffeine. My test Avg was an 82 and I got a C only because the Dept final got to me. Fair tests and does NOT curve. He does prepare you mostly well however. DO HW PROBLEMS AND DEPT FINAL PROBLEMS RELATED TO EACH UNIT! Go to office hours, and learn outside of class too!

Very nice professor. He lectures extremely fast so I ended up closing my notepad and just pay attention to him, and it worked! (Read the textbook also) Tests were not hard, very balanced as he has tons of experience and he knows what's important and what's not. He teaches with intuition and geeky humor :) Nice person.

He talks very fast but knows what he is doing. He also answers questions very well and doesn't take shortcuts when doing the work for a question. Make sure to do the homework problems to review for his exams which are not very hard. Overall he is a really nice guy too

He is so kind and nice. He gives you a genuine smile. Aside from that He is an excellent professor.

Your best choice for calc 3. He does a bit fast in lectures but if you ask him questions he will explain the concept in great detail. His exams are fair there are four but he drops your lowest grade. He prepares you for the final and even goes over some of the finals from previous semester at the end. Overall he is a very kind person.

ok here's the deal, he has fast lectures but if u pay attention you can keep up, ask him a question and he will answer it, your grade is in your hand if u study u will get good grades on his exams since they are not very hard. He is a nice person will help you during office hours, again you will have to put in time.

He is a very fast lecturers. If you pay attention, though, then you should be able to catch on to what hes saying. For me, personally, I dont show up to his lectures at all and only show up during exam days. Hes a good dude, but its hard to learn from him. Better to watch Professor Leonard. Having said that, he does care about his students.

Even though he speaks very fast, he is a gem. He always care for his students. After he solves the problem he always ask everyone whether they understand the problem or not. He gives reviews and solves every homework problem before the exam and go over final exams as well. You'll regret you don't take his class. he's one of the very best ccny prof

Professor Shell is actually a good professor. He lectures quickly but will not hesitate to help if you ask. His lectures are easy to understand for the most part and he will give plenty examples similar to what you will study for the test. He gives out sheets that give you practice problems that equip you very well for the tests (he will drop 1/4).

Dr. Shell is so nice and genuinely cares about his students. He never makes anyone feel dumb for asking a question, and he is super helpful in office hours. His exams are fair. Moreover, Dr. Shell's done an amazing job transitioning to an online class and makes practice exams so that the class can be better prepared for the final. 10/10 take him.

Professor Shell is a gem. He is truly interested in seeing his students succeed. The amount of work that has to be covered dictates that he goes fast, but hes always willing to answer every question and clarify any misunderstandings. The only downside is the size of the class, but that is the departments fault, not his.

Midterm tests are very heavy, with 60% of your total grade. There is a slight curve of +10 points to your last mid-term exam which is nice. He is not a bad professor, his pdfs and exam reviews are very helpful, just remember that you have to spend time reading them. He is very kind and you should ask more questions about things you don't know.

Professor Shell was a good professor. His exams may be difficult sometimes but are very, very fair and are pretty much based on the homework he assigns (which isn't mandatory - but I strongly suggest you do it) or the reviews he posts (again - make sure you understand the problems!). He's accommodating and is always there for help if you need it.

idk why there's so many negative reviews. i took him last semester, and while it's true that lots failed, i don't think it was because of him. he was very accessible and open for questions. he made us reviews when we asked for them, and made exams very similar to those. he was very generous with partial credit too. use leonard as a source too.

Shell is way better than some other profs here, if he made a mistake on your exam, he'll gladly fix it, i've seen it happen a few times. He always gave out review sheets for every exam (PLEASE do them) and doesn't mind answering questions people ask in class from reviewing a step to reexplaining the whole problem. I would gladly take him again

shell is better compared to other math professors here. he is an EXTREMELY lenient grader and he is genuinely a nice guy. dropped one exam and there were no hws but the review sheets were basically exactly the exam. he made the final too so it was not bad at all. only writing bc everyone is giving him low ratings when he isn't that guy at all

Shows a lot of example problems in lecture. Makes mistakes when writing so make sure you take the correct notes. Posts similar practice problems before every exam. Takes attendance but it does not count toward your grade. 4 midterms (1 dropped) + final. No HW (webwork and textbook questions are strongly recommended). He writes the final btw

At first I was given the impression that this professor was horrendous, but actually the opposite. He is a very caring person, he doesn't mind at all that you ask questions and encourages it. He genuinely cares about his students and cares about them learning the material and understanding it thoroughly.

Took him some time ago but honestly one of the better math professors I've had at CCNY. At the time, homework was not mandatory, though I highly recommended doing assigned problems and reviews as they prepare you well for exams. Drill problems as much as you can and you should be fine. Shell was a fair grader, caring, and always open to questions.

Might not explain topics perfectly but is clear about expectations and gives lots of partial credit. Grades are based on 3/4 midterms and final exam, so stay on top of Math 212 homework, posted online, and practice textbook problems to do well. Be consistent, and you'll pass. He also writes the final, so it's a win-win! Overall, a great professor.

He's a pretty decent professor in teaching cal 2. He does alot of examples and sometimes just tell us to memorize stuff rather than show us where does it derive from. If you self study cal 2 his class will be quite easy to go through. His exams are not hard to do. Do alot of practice and ur good (he drops ur lowest exam grade plus makes the final)

I barely went to his class, did no homework for him (not graded). He grades you 3 out of the 4 mideterms and the final (which he writes). I recommend going to his review sessions of his practice papers for midterm and final. His lectures didnt help me much, self studying did. You gotta put effort and know the content yourself. Its calc 2 so lock in

Super chill guy who's lenient with exam grading. He wont deduct points for small mistakes and such. The review exams he uploads are almost identical to the actual exam, making it easy to pass.

I don't know why this guy gets low ratings. He's one of the best calc 2 profs in the department. If you do the problems on his study guide, you will do good on his tests as well on the final. The people failing here prob didn't study enough and taking it out on rmp. Do you really think Calc 2 is supposed to be easy? (Well it is if u study)

If you are listening to the people giving him bad ratings, you're doing yourself a disservice. He is EXTREMELY generous with partial credit, stop complaining about self-study because you cannot learn everything in a lecture, they're too long to absorb everything. Put in effort to self-study & solve practice problems. 4 midterms & a Final.

Okay listen to me well. As an actual professor I learned little to nothing from him and barely attended class. But as a tester and grader he is AMAZING. He gives sample exams for the class exams that look exactly like the actual test, making it really easy to pass if you put in the work.
