he is insanely hard

HORRIBLE HORRIBLE TEACHER NEVER TAKE HIM

****, didnt change his teaching style at all after our class of 18 dropped to 8 people after everyone withdrew afer the second test.

So hard. So very unclear. He needs to learn how ti freakin teach and next time, dont have a test the day after St.Patricks day.

HORRIBLE... made math impossible and was SO incredibly hard. Our class went from 17 to 8 because he was failing everyone.

Impossible teacher, never take him. Can't keep a clear thought in his mind. Should teach some extremely advanced math instead of basic calulus. Smart guy but horrible teacher and unfair grader. Never take him, worst math teacher I have had so far.

awful awful awful - drop his class as soon as you can

this man is the most unbelievable/awful person i have ever had to deal with. DO NOT TAKE THIS CLASS. You will fail. doesnt know how to teach. once gave me a 52.5 on am exam----take the half point and shove it. on the next test, he gave me an F-, its apparently a new grade. the man is a nut case.

Please, do not take this class

worst teacher ever

He moves way to fast, and assumes everybody has seen the material before. Plus he gets annoyed when you ask questions. Also, he has quizzes nearly everyday which is supposed to be on the homework, but instead is on an advanced version of it. Don't take this class!

Do NOT take this class if you've never taken calc before! Precalc is not enough. He assumes everyone already knows it, and unfortunately some people do. Talks and teaches fast, his "questions, questions, any questions?" routine gets irritating b/c you don't even have time to write it all down, forget about ask questions. Stay clear or teach youself

WORST PROFESSOR EVER! This guy couldn't teach someone how to tie their shoes. Almost daily quizzes, teaches like you have a PhD in math. Homework counts for nothing, lectures are basically going over problems in the book, exams have NOTHING to do with what you're taught! AVOID AT ALL COSTS

By far the worst teacher I have ever had. Is incapable of teaching. Forget about asking a question because he will make you feel like an idiot. Avoid him at all costs!

This is the first class that I have ever had to drop. He is impossible to understand, very confusing, very frustrating. Big problem: the book used was written by him and is equally as confusing. I suffered through 2 full weeks and had to quit to keep my sanity. Go elsewhere for Number Theory!

WORST teacher EVER! Assumes you already know material. Makes you feel like an idiot if you ask a question and basically doesn't answer. Mumbles, talks to the board. I have never been so frustrated with a class! Needs to retire NOW!

Least helpful teacher ever. I failed his class last fall. It was my first F ever. But retook the same course over the summer with a good teacher at Merrimack and got an 'A'. Does not help if your having trouble and doesn't respond to emails. Anyone that says he is a good teacher is in his highest level math courses and math comes natural to them

This was by far the worst human being I've ever been in contact with in my life. Doesn't believe in teaching, just "presenting the material". He kicked me out of his class when asking for help. He expects you to know things even when he doesn't. Tests are impossible. Ridiculous that he is employed.

So so bad. Mumbles incoherently all through class. Refuses to answer questions unless you are one of his favorites who already knows the material and you question is superficial. If you don't already know the stuff he is supposed to teach, forget it because he is noticably bothered by students who come to class assuming they would be taught.

Can you read chicken scratch, interpret some mumbling alien type sound, and like the feeling of tripping on acid then this class is perfect for you. J.J. Tats just does not explain anything, he does not finish a problem. One time i went to the tutors and they had no clue what i was doing--DO NOT TAKE!!!

Knows math, does not know how to teach effectively at all. Teaches it like you've known it for years. Completely made me lose all interest in math. You are insane or intellectually suicidal if you take his class.

okay. so i had to take this in order rto be a finance major and it literally is the worse class ever. man never listens. tests are open book but impossible oh yeah and there is an entire test on excel that you have no idea how to do. have fun. class sucks.

Do yourself a favor and DO NOT TAKE HIM. He is very unclear and just does problems on the board without explaining anything. He wrote the book and it has tons of mistakes. Take a better instructor and actually learn the material.

Not a good professor. Yes, he might encourage you to see him if you have questions, but he is unorganized, tests are impossibly difficult, and he is often unclear when he teaches. In high school, I easily had a 91, and thought I'd be able to take this class to boost my overall college GPA but ended up dropping it because it was too difficult.

I took precalc in high school and felt grossly unprepared for this class. I have straight A's in every other class but I'm on the verge of failing this one. He is unhelpful and unclear. Worst professor I've ever taken and entirely unorganized. His tests make no sense and aren nothing like he prepares you for. DO. NOT. TAKE.

worst professor I ever had. Does not teach. Gives basic idea of calc in class and expects you to know all of the applications of the information for the exams. Do not consider taking him .

Worst teacher I've ever had. He does not teach and does not give you any tools or resources to success. He is not a HARD professor, but a BAD professor. I have A's in all my other classes but had to drop this one because I was failing. He just excepts you to know the complex material without teaching it to you. Uses his own textbook, lots of typos.

Worst teacher I have had in my whole student career. Never take this professor because he is very unclear and is no help. Very uncommunicative. Go to his office hours and it WILL NOT help. His tests are impossible. he worst part is that he give NO partial credit!

Terrible teacher. Doesnt not care in the least if anyone understands his lecture. Is of lesser help during office hours. Took same class with different teacher next semester, much better.

Has 4 exams and a final and gives you a study guide or lets you use a cheat sheet for every exam. Horrible teacher. Just starts writing numbers on the board and half the time doesn't even finish the problem. More kids probably dropped this class than stayed in it. Don't take him, his bad rating on here if very much deserved.

He is a nice enough man but sometimes I think he forgets he is teaching a class & just writes numbers on the board for himself. Even if you use the book to teach yourself his exam questions are so confusing I didnt even know what they were asking half the time. Most people drop his class so just save yourself some time & take a different prof

Dr. Tattersall is a great man, who is extremely smart, but does not know how to explain the material inside his head. His notes on the board are as disorganized as his lectures, and he cannot explain how to get from A to B. Almost everyone ends up dropping this class because they are failing, including me (and I had an A in calc last semester).

JJ Tattersall is the worst teacher I have ever had and will ever have. I am confident in that statement despite only being a freshman. He has no structure in his class. Even something as simple as writing on the board is low quality. He writes everywhere and everywhere in about font size 12. DO WHATEVER YOU CAN TO NOT TAKE DR. TATTERSALL

Taking his class made me feel like an idiot. The only reason why I managed to make it out with a C was by watching tons of calc youtube videos. His lectures are IMPOSSIBLE to follow and incredibly boring. Your grade is only made up of 3 exams grades and the final. Don't take this prof if you can avoid it. Even if you did well in AP calc AB/BC.

This guy sucks. He does not know how to teach a class. During lecture his notes are unorganized and students have to correct him most of the time. Do anything you can to stay away from this class he's horrible.

Tattersall is a nice older man who knows calculus very well and is extremely friendly. With this being said, that is all. He is by no means qualified to be a professor as he often struggles getting across his points. He flies through lectures, constantly mis-speaks/ writes, and his power points have many errors making it difficult to retain info.

Dr. Tattersall is a great and sweet man. However, he is by far the worst teacher I've ever had in my life. His style of teaching is by far the worst and all he does is write numbers on the board and expect you to understand how to do it. Pretty much a quiz every Friday and does not care the least for his students. STAY AWAY!!

Professor Tattersall is a nice guy but he is the worst teacher I have ever had. He is incapable of teaching calc, and friends of mine in other classes have had a much easier time getting good grades while everyone I know who has tattersall struggles for even a B. He could not teach any faster, Do not take Tattersall if you want to learn calc.

This man doesn't even know what's going on. When he's going over a problem he gets it wrong himself and the class consists of everyone else correcting him. If you don't already know the material, you're not going to learn it from him so it's basically a self-teaching class. He honestly made me confused the more I listened to him.

Definitely time for Dr Tattersall to retire. He barely knows what is going on and frequently messes up the work on the board. Tests aren't very hard if you got to class.

PLEASE avoid this class at all costs. You won't pass, or if you do it'll tank your gpa. The only way to learn is to teach yourself through the textbook. He makes no sense and it the most disorganized professor ever. He doesn't give partial credit for work on problems and will fail you on everything. for your own sanity, don't take.

I would like to say I'm good at math but listening to him made me confused. Honestly when I would have to go to class for quizzes and he would teach I would tune him out Everyone in class would be correcting him the entire time and his work on the board is impossible to understand.
