I haven't finished the class yet, but so far I have a D. I was hoping other people would have rated him, but they haven't, so I added him hoping others that have had him will offer words of advice.

hard teacher, but very fair. expect to work in his class, but you will learn a lot if you do what is expected of you. if you want an easy A then go elsewhere, but if you want to truly learn and understand the material, carretero is a good teacher .

Very hard teacher. He is helpful out in office hours. Expects that you have already taken classes that are not prereqs. Has a funny accent.

Very hard teacher, Very hard teacher, Very hard teacher. You will cover 4 years worth of material in 2 semesters... He will expect that you can apply what you learn to "new" applications. NOT EASY!!! But he is fair and is getting to be a bette

good teacher, you will have to learn. he is very fair adn open to all suggestions. has a funny accent but it is not that bad. keeps you entertained through the class. very helpful.

Great teacher. Very good at answering questions, and giving examples where students in the physical sciences will use the material. This is a great class and he makes it very interesting when with excellent computor simulations.

ATTN: He rated himself! the comment posted on 2/19/04 was his own comment about himself.

If you are like me, and had a choice between 342A/342B and some other class, take the other class or suffer the wrath! The class moves very fast, and the book is the WORST I have ever used. He’s a tough prof, but it’s mainly the curriculum in the class.

You will have to learn and do your work if not youll fall back. I got an A in his class (I like math a lot and i did it in high school in india).If you will be needing math in your major you better take this class cal III gonna be harder.GET THE BASICS

Ricardo is the chillest teacher out there. He has a thick costa rican accent, talks alot about chorizos and sometimes weird mexican things, but he is funny as hell, talks a mile a minute so its hard to keep up with his words but its easy to understand his notes, i reccomend mucho

Got a bit of a Mexican accent, explained things pretty well. talks very quickly, but its good becuase he covers a variety of examples. If you can, get a TI-86 to help figure out the hw. if you can get 80% of the hw, you will have an A.

Good professor. Fair, animated, helpful one on one. Has slight Mexican accent, but understandable. Uses online homework system, Webworks, gives 5 chances to get answer. Homework worth 25% of grade. Tests are less difficult than homework. Calc II is a very hard class. You cant bull your way through.

TAKE HIM if you can. He is not easy at all, but knows his stuff and will explain it to you even if he does make you feel dumb.

I though he was an excellent teach for calculus II. This was my second time taking the class, and I actually understood the material when he taught it. It's a hard class even with a great teacher, so don't expect it to be easy. He does talk very fast and has some funny moments though.

He's a chill teacher. The overall grading of the class is very confusing, but from what I have heard he's better than Chavez-Ross. He talks fast but answers any questions you may have. You're allowed calculators and an index card for the tests which help a lot.

Has good intentions and can be very funny, but do not fall behind lest you never recover. Midterms are difficult, but if you can do all homework then you will pass the midterms. Group finals at SDSU are a joke.

Speaks extremely fast and can be confusing at times. Teaches labs fairly well, and he's open to questions about tests. He goes over practice tests a week before a test, and it helps a lot. The grading for the class is confusing, because everyone seems to be failing, but they say the tests are curved. Index card and calc on tests allowed.

He is very energetic and makes learning math fun, he is much easier to learn from than Ross, and is more available.

I TOOK HIM MY FRESHMAN YEAR AND HE WAS PRETTY GOOD. I MISSED A LOT OF THE CLASSES AND JUST READ THE BOOK WHEN I COULD AND I STILL GOT AN A. HE DOES HIS HOMEWORK OVER THE INTERNET SO YOU ONLY GET SO MANY TRIES BEFORE IT DOESN'T LET YOU ANSWER THEM ANYMORE. BUT I LIKE IT. I AM A MATH MAJOR BUT THE OTHER PHYSICS MAJORS THOUGHT IT WAS EASIER THAN I DID

Very funny professor. Just make sure undesrtand the HW (webwork), and go to the lectures. He throws alot of curve balls in the tests.

Carretero knows his stuff. He also expects his students to be very proactive in their studies. If you work hard, then you will learn a lot from him. If math isn't your thing, then you will have to work even harder. If you do not work hard, no matter what, you will probably dislike him as a professor, get frustrated, and write bad reviews.

Here's the deal: I took Calc 1 from this guy in Fall 2010. If it weren't for him there is no way I could have made A's in Calc 2 and 3. He was tough, but don't you think you should have to work for an education?

only rating cuz i see he has a lot of bad ratings, which he doesnt deserve. hes a good teacher. knows his stuff and knows how to teach it. the TA sucked, but the prof was awesome n helpful. id recommend him, but ive had better professors. curved a lot.

A wonderful prof. if you are willing to put in the time to learn. If you study, you will do well, but understand the material. I was lucky because his tests were easy this semester, but I could sort of understand if other people had difficulty problems. Do the homework and understand the subject matter, and you will get a fair grade. Honestly.

this semester 50% of the classes failed. I was lucky enough to get a c+ its not that he doesnt teach good. his tests are tough, and his curve is very small. If you are going to take him, put in the work, or you will die

LOVED IT, seriously he is a great and fair professor he will ask a lot of you but that is because he expects you to understand the material. If you can't grasp Math well try getting a professor that just passes most who should fail as you will get what you earn in his class and will definitely be prepared for follow on classes!!!

Hard teacher, don't expect good grades if you're not willing to work a lot each week. HW takes 3 to 5 hours per week. But the guy is smart, friendly and passionate. You will learn (a lot) the hard way.

Knows his stuff, and expects you to learn it. Prepares you for tests, reading the book will be extremely helpful as that's where he gets all of his examples. Homework is online and not too bad, tests are very similar. With slightly above minimal effort and a good math intuition, this class isn't that bad.

Really hard class. I was not required to take this class but, Carretero is the best math teacher I have had at state by far.

Class was insanely difficult (obviously, it is calculus). Teacher was not very good. It's hard to teach calculus well, so he might be alright but not gonna help you understand the hard topics.

Carretero is a great professor, he is extremely considerate and a pretty funny guy. He teaches pretty well and his lectures are enjoyable, his office hours help a lot and although Math151 is a difficult subject he get's you through it with a pretty good understanding. He relates concepts to real life and you can tell he wants you to succeed.

Anyone who complains about him is lazy because he literally tries his best to make you understand through lectures, homework, and office hours. In my opinion, that's minimal effort, what you should already be doing anyway. All the other professors had lower averages, Carretero's was always the highest. Go to class, do hw and you're good.

Prof. Carretero is a very enthusiastic professor who explains the content pretty well. He does however go over the content at an extremely fast pace, so do not get behind! He gives a lot of hints on what to study for the exams(he writes the exams), which helped tremendously.

I understood his Spanish accent perfectly. He's a crazy calc prof who does indeed talk fast, but I enjoy profs like that for they keep my attention. He writes the tests for every calc 2 teacher's classes. Very nice to talk & ask questions to during office hours. Quizzes do range from easy to difficult.

Carretero is a unique yet enthusiastic character. He has a slight accent but teaches relatively well. You need to study and go to the lectures in order to get a good grade. There is one homework assignment due once a week. MESA made me take a workshop class that was very helpful. I would recommend looking into the MESA program for extra help.

Calc teachers at state are awful but I actually learned the subject w/Carretero. I simply went to class and did the hw (& i don't mean copy, actually did it). Very helpful at office hours if you're still stuck. Exam material is nothing you haven't seen before and if you keep up, you won't need to study/cram so much. Did well beyond test averages :)

Carretero's the best there is. Yes he has a slight accent/speaks quickly, but he's very enthusiastic and loves what he does. He's a genius. He writes the exams for all MATH 151 classes and there's nothing you haven't seen before on them. Review practice problems/homework and you should be set. Lectures optional, strongly recommended.

You could obviously tell that he loved his work and is amazing at teaching it! As long as you do the homework you should be fine.

He's a good professor if you're willing to learn Calculus. I'm a laid back type of person myself but you have to put in work or you're going to fail. Quizzes, weekly WebAssign homework, 3 midterms and a final.

He is an amazing Prof, he makes the material seem so easy :) Attendence is Mandatory due to the iclicker which isnt a bad thing since you learn so much from the lectures. His Quizzes are set up so that as long as you answer the questions youll get an A on them( you dont even have to get the right answer). Overall solid CALC 2 proffesor

Calculus II is not tremendously easy, but Prof C goes out of his way to be super enthusiastic about it. He is a great teacher and explains concepts in easy to understand ways. He constantly finds ways to bring humor into the classroom, so you are in an awesome environment. Definitely recommend.

Calc 2 is the hardest of all 3 but he writes the tests so you have a leg up on others and unless you want an 8am with Manchester (also really good), take this guy. Speaks pretty fast with a sorta thick spanish accent but the dude is fun and you won't fall asleep in front; do and you get called out. You really gotta do extra problems to study best

Carretero is very passionate about the topic. Honestly, Calc II is not the easiest class, but Carretero made it the highlight of my semester. Out of all the Calc II professors, take him! I received a B- in Calc I and I thought I was set up for failure. Just make sure you keep up with the material and do all of the homework. Study groups also help.

I don't know why carretero has such a low rating. He is a great teacher and is super passionate about math. He is very energetic so it's easier to stay engaged in what he is teaching during lecture. I wish he taught calc 3.

Carretero is the best professor for Calc 2. This is a difficult class that many people fail, but Carretero manages to explain difficult concepts in the minimal amount time he has. Also for this class asking questions during small section is very important. If you don't understand a previous concept you can quickly fall behind.

Professor C is an amazing professor! He really cares about his students. Sometimes he does go a little fast since 50 minutes is a bit short to teach a complex concept, but the TA sessions, SI sessions, and his office hours are all super helpful. Going to SI is key if you want to do well in this course.

Carretero is one of my favorite teachers I've ever had. He is ridiculously passionate about his material and he is very funny/animated which makes paying attention in lectures easy. Theres a good amount of homework and the tests are hard, but that is just how calc 2 goes. He writes the tests too so Carratero is your best option for 151.

Carretero is a phenomenal instructor. I loved his lectures, he made difficult concepts make sense. He used clickers for attendance, but I would 100% recommend to show up rather than share your clicker. He cares about making concepts easy to digest, and he is really funny. I went into the class dreading calc, but he made the class amazing.

Great/funny lecturer, makes hard concepts understandable. Math 151 is a very tough class and meant to weed people out, averages on tests are very low but there was a decent 5-10% curve my semester. To pass, you have to study. I failed once with too many units so I spent more time and went to almost all classes. Lot of library hours for final.

Carretero is super energetic during lectures, he clearly explains topics, he has a passion to teach, and you can tell he really wants the best for his students. He also expects a lot from his students so the class probably isnt going to be easy. If you dont work through the problems during lecture and do the homework youre not going to do great

Professor C is really passionate about what he is teaching. It is a really hard class that I had to take twice and he is the only reason I passed the second time. He is pretty intense sometimes, but he is a pretty cool guy and a solid teacher.

Carretero teaches in a very energetic and fast paced manner so I often had to rewatch lectures. The class is hard so be ready to work and carretero isnt a monster like a lot of people here are saying. This sem they were pretty leniant and provided test corrections so those were a big help. There is one homework due per week but it takes a while.

Calculus can be hard if you dont put effort into it. Currently taking this class, he is great at explaining and responds all your questions. if you miss a class you can still get notes from someone else but I recommend you go. He really cares that you learn and makes class engaging.

Carretero has great lectures but the tests get progressively harder. The class starts out pretty easy but towards the end you do NOT want to miss a lecture or you will fall behind fast.

Awesome class, super interesting, but very tough.

Pretty solid professor overall, the exams are mostly based on what goes on during lecture and are mostly concept based, so as long as you know what's going on in all of his example problems, you should be pretty good for exams.

While the notes can get complicated, prof Carretero is a very enthusiastic guy and you can really see it. Many times he dives into more complex applications of the materials in lectures, and it is really interesting to see the use. He makes math lectures interesting to go to and I appreciate that. Gives you plenty of resources to be successful

He is a great teacher. Very enthusiastic and makes lectures interesting and easy to pay attention to, even at 9:30 (early for me). Tests don't involve trick questions and have easy calculations, so understanding concepts is more important than solving integrals/derivatives. He has a low rating because the class is hard but he is a great teacher.

Carretero's lectures are engaging, but his exams are concept-heavy and progressively more challenging. Attend class, use the free textbook, and try Unstuck study for exam prep - it really helped me stay on top of the material.

Professor Carretero cares deeply about his students, and wants to see them all truly succeed. The homework exercises are very comprehensive & thorough. Some homework exercises are very difficult, which was frustrating. Exams are very straightforward, with no curveballs. He is a fair grader, and very reasonable. Lectures are energetic and engaging.

He is a super nice teacher and is extremely caring and smart in math. During tests he gives helpful hints and going in to office hours/ talking with him after class really helps. The homework was extremely tough, but it's like that for every diffeq class. He uses a lot of variables instead of numbers during lectures which can be tough to follow
