He is completely oblivious to the fact that he can't teach. Kids in the class can even teach better than he can. He's nice at times, but usually picks on certain students. It sucks that he grades you 100% on tests too ;/ i suggest that you try to avoid him.

had him for geo. He's really grouchy and rude but an A is possible. people who are good in math should take him b/c his quizzes are kinda easy

Only take him for Alg1 or a class where you fully KNOW the material. He only checks the hw 1x every month, or even less. Quizzes aren't too hard but he's really specific, and you can't argue about anything because he won't listen. Reads the textbook in class...will pick on you if he knows your name.

I'm posting this because I don't want people to make the mistake I made of taking him twice. Do all you can do to avoid this man. Hes not a bad person, hes nice and tries to be fun at times, but he is not a very good teacher and his grading system sucks. Never checks hmwk, but grade=100% op quizzes.

Mr. Costa. Ahh, he's actually one of the better Geometry teachers. He doesn't have a language barrier (rosales), doesn't move too fast (evans), and actually teaches the material pretty well (fehey). His pop quizzes can hella hurt your grade if you don't know your stuff, but he's a pretty okay guy. I

BAD BAD BAD. Doesn't seem like he actually knows what he is talking about. Only gives answers to homework then gives quizzes without warning. Grade only based on pop quizzes.

Bad teacher because of his teaching method:First off, he assigns a large amount of homework, then falls behind like 2-3 days correcting it. Class time is spent going over, 1-2 of the easiest problems.Then when the test comes, he gives you the hardest questions, that way many people don't do well.

honestly he is a bad teacher. endless homework and he doesnt explain homework well. he expects you to know how to do the homework from reading the book. then he goes over it the next day. so i screwed up on one of his quizes first semester by getting a zero so it dropped my grade down to a c. thankfully i have been getting mostly tens and i think im the only person in his class with an a right now. yay me :).

for aa. dont take him! he doesn't teach at all and doesn't know his stuff. he even did the problem wrong and he has the answer key right in front of him! he never gives us tests. the final is worth like 50% of our grade. he gives us pop quizes that are like 10 pts each once a month. too much pressure because quizzes only hav 5 questions and it's all or nothing. it's impossible to get an A in his class unles you're extremely smart. he's okay if you like learning from the book. not a math teacher

He can be pretty impatient in class, but if you see him after class, he's really helpful. He can be a little harsh in class if you get something wrong, but he explains problems really well, and if pay attention and get it, you'll do fine.

I love mr. Costa hes so awesome, its pretty easy if you know your stuff, he pretty much drills the theorems and postulates into your head anyways. he gives homework everyday but rarely ever checks, and he gives quizes basically whenever he wants, but its pretty predictable and easy straight-forward quizzes. Its true that he talks really loud, but you get used to it after a while.

I heard last year he was pretty mean but now he's nicer so im being an optimistic. Dont miss more than 1 question on his test or you'll get a D or lower. Study the stuff you need to know before class because you can usually tell when he's about to give a quiz. Don't ask questions. Ask a friend for help because it's better that way.

costa cares. maybe i was just expecting the worst walking into his class, or maybe he just likes my class, but he's a good guy. he's not the best TEACHer in the world, but you can totaly ask questions and he doesn't get mad if you ask the people around you for help during class. doesn't hold grudges. if you like a little classtime wasted, he can get really excited about volcanoes and the SATs and we even watch movies. he likes to have fun and uses backwards tictactoe to help teach geo.costa=cool

His homework doesn't count for anything, but NOT doing them will make your grade drop. If a teacher's voice matters to your learning style, he always talks as if he is explaining something for the last time. And he has sort of a Brooklyn accent. I think it's more his non-changing tone that puts people (including me) to sleep.

also had costa the whole year. I think hes a nice person, wanting to save the environment and educate us on things he feels are important even if it doens't have to do with math, but hes not a very good teacher. Even though his tests are multiple choice, they're still pretty hard and he only counts tests which SUCKS! to me at least, his voice puts me to sleep >.> if you think you can learne verything from the book, hes an ok teacher, but if you want a lot of explaining, you shouldn't take him

I had Costa for a WHOLE YEAR of algebra. He's pretty stubborn at times. He doesn't count homework, but sometimes he will check if you do them or not. If you don't do them.. he will minus points.. and that can affect your grade. Teaches out of the book, so unless you know the material beforehand, you won't learn anything. If you get on his good side, he won't pick on you. Don't cut his class or he's ON TO you until you have a re-admit or admit you cut class. He has multiple choice algebra tests..

anyone who takes over 10 minutes to do attendance and another 30 to do 1 math problem is not worth the trouble. homework doesnt help you and you get "stars" for volunteering to answer questions. constantly picked me becuase i had neat writing. and those 5 question quizzes are annoying. pulled off an A but i doubt i really learned much. he's more interested in geology anyway.

I warn you, do not take Costa. He can be nice at times, but basically he is a horrible teacher. He marks you off all the time for hw and marks off if you don't get the basic idea on pop quizzes. You should at least get credit if you get the right answer.

Costa's not good teacher =[ He cant teach. You ask him to explain one problem to you and he starts yelling. It's like you have to solve it by yourself. He should be a science teacher, not a math teacher. He asks WAY TOO MUCH QUESTIONS(non math type). He reads out of the math book, and doesn't show you. He can be nice at times, but then when you don't understand a problem he becomes mean. It's like he doesn't even want to teach you.
