He's so awesome! He's very nice and understanding...just don't tell him your ringtone is better than his!! LOL!!

Diaz is a good teacher. Plus he's a cool guy in general, take this class if you hate math! He makes it easier to understand and its not so boring!

Awesome teacher.. planning on taking other classes with him. He's more than helpful.

Mr. Diaz is a great math professor. Is the only teacher that I have that really listens and actually tries to help. Everyone should take him. He makes things really clear by using a lot of colors on the board.

He's cool..

Mr. Diaz is a very good teacher he’s very attentive to the students needs. If you have to miss class just e-mail him or call him but definitely keep in touch and that will totally go a long way.

no way! he make the class so easy. he gives practice tests that are just like the in class tests. he is so nice in and out of class. he answers all my questions and is super patient--can't believe that he can ever get mad at anyone. he tells us to do the practice test and hw over email so that we don't forget. do the work and he's an easy A!

I respect and like Robert Diaz. He is challenging but not demanding. He has no favorites. He likes students who work hard. He is young and enthusiastic about his subject. He is absolutely my favorite all-time teacher. You will love his math class and personality. He is real, humble, and very smart. He is a wonderful person!!!

diaz is a cool guy, funny with an odd/dorky sense of humor. very willing to help, and re-explain things. lectures and has you work in groups. i hate math, and im horrible at it...HORRIBLE at math, and i got an A. Good guy, good teacher. :o)

a dyslexic math teacher. Very funny... He's a decent guy, and a good teacher. He'll answer your questions, he'll explain stuff well in class, and he'll be very upfront about his tests. No nonsense, no favorites, no bullsh*t. I rated him middle-of-the-road easy because I've got him for calcIII, which is hard no matter who you take it with.

He's a really nice guy. He's helpful, and makes you laugh, which keeps you interested:although he has random stuff to say and looks for his classmates myspaces, he really is a great guy :)

he's a pretty easy teacher. very easy going. but doesnt allow people to disrespect him at the same time. still holds his position as the teacher and not your best friend. very respectful. i reccomend him. he really cares about students and them learning.

great person. makes the class real straight forward. always willing to help if you are willing to talk with him. very approachable and down to earth. he is a better teacher than my math 20 and 40 instructors. does not play favorites and treats everyone real well.

The coolest professor I have ever seen. He is a combination of a comedian and a helpful professor. He has passion on his job and enjoys making some interesting examples about daily life and fashion to relate to his math smoothly. Students will feel time passes too fast in his lecture. He makes notes for students, which have been organized and diges

He cares about students. He makes notes for students, organized and digested. Lectures and exams focus on them, students feel easy to know what they need to know. Students can get high grades in his class. It is not because it is easy. He helps students to find their potentials on math, helping students make it. Take his course, you will enjoy it.

Best teacher ever have taken him for 2 semesters and cant wait to take him again. really cares about his students and makes sure you understand. always available to help. hes goofy and fun. classes werent too bad. Take him if you want to understand math.

Highly Recommend! Has a great sense of humor and always kept things interesting. Exams are fair, grading is more than fair. Miscellaneous extra credit available from time-to-time if you're in the hole. Overall, great teacher, great experience! Oh, and he has all the cool guitars I want :) Rock on :) !!!!

i've always had a weak math background. He was very helpful. Great guy. MORE than fair! dorky, but cool :) I think he's probably the best teacher in math. He's not easy to the point where his students take him as a joke. He's not hard to the point, where he's a ****. Overall: GREAT!

Great teacher, very helpful, great system with the group work and mymathlab...awesome experience

The class itself is not that easy, but the way he explains it clarifies most questions you might have. He is there if you need help and he also has a great sense of humor.

this dude is awesome. his style of teaching a subject is totally different. if u attend a class regularly and take all the notes.. then there is no chance to fail this class. most of the problems in exams, are from his notes. he is very helpful, kind and the best thing is his nature. he makes the suject very easssyyyy....

Upon first seeing Robert you might think he is another student.Great guy! If you are NOT a math freak, but like me, are actually afraid of math, Robert is your guy. He also keeps regular office hours. Two bits of advice~ Don't miss class, and DO YOUR HOMEWORK!

Robert was a great proffessor. I would suggest his class to all who need it.

Class was easy and enjoyable. Must do all homework(not much), be on time, and not miss any days. Exams are straight from notes. Again Easy & Fun!!! I strongly recommend him!!!

alright everyone is giving him pos. feedback, which is good here is some neg. feedback. He doesnt realy go over hw he assigns. And you realy must know all the tricky problems, but they will either be in hw, or the notes. Go to him during office hours for hw u dont get. I didnt do that and i regret it. Great guy, prepare to spend lots of time

It's a very easy class if you show up, and do the online homework and study a little for tests, he's a really nice teacher.

lol what a class! it actually made me enjoy math a little! thanks robert!

I was probably in the same class. No one really studies so I can't blame him for moving on. When I didn't understand something, I would see him in his office, and was always helpful. He would go over anything I wanted and more. Helped me on old tests and homework from the computer. I got an A in this class. Nice guy. I will take him for Math 40 too

GREAT TEACHER!!!!!!!!! his lecture and homework problems are resonable not too hard not to easy. very clear in explaining a problem and his tests are easy if you do hw and study lecture notes. take him for this class. very nice guy with a good sense of humor!!! material is not too hard and he explains in detail.

He is very nice and always ready to help students. The tests are not tricky and hard as long as you study for your notes and homework. you might feel like homework is a little bit pressure, but remember that what he assigned for your homework is always important for your test also. He is a great teacher, you will enjoy ur class for a whole semester

Mr. Diaz is a great teacher. he is willing to help and is always on time and generous. you will learn a lot from his class.He is easy if you take notes and do all your HW. The way he teaches is so HELPFUL. I would take this teacher for ALL MY MATH CLASSES. Awesome TEACHER EVER!

For his class you don't need a graphing calculator. Attendance is mandatory and hw is mandatory and due every day. he's a great teacher, explains things clearly and follows the book exactly, but you should listen to lectures bc this textbook sucks at explaining things. he moves kinda fast, but that could be just for his summer course.

Expect Quizzes, but they are easy if you pay attention to the lectures. The test are not hard but all the material learned is covered. The teacher is so cool, and really helpful. I'm planning on taking his 250A class next seemster. Take his class if you are willing to study and to keep on track with the hw!

Robert is the man! I took his class during Summer 2007 at 7am. He's a younger dude that most students can relate to. If you're looking into taking PHYS222, be sure to take MATH250A first!

He says he is "as hard as the book." It's true. He definitely helps you learn the mechanics of calculus and not just spitting stuff out - you must know theorems for the tests. I would recommend him for those who enjoy math. You'll either love or hate him. If you can't stand him, get out of the class.

He is straight forward. Nothing was ever tricky or somthing that was never seen before. He was always helpful in office hours and was willing to help. Very thorough. I was able to easily do the homework with just his notes. Like the guy below, a lot of idiots in his class that suck and can't do the hw. He's not to blame. I wish he is teaching 150B.

Took Mr. Diaz after a real bad experience in Math 40 in the spring. Mr Diaz is such a great teacher. He is real nice and listens even to those people that were failing the class. A lot of people were failing the class and dropped but it was not his fault. The tests were like the notes and homework. The final was easy.

He is amazing Professor!! He always ask what he wants and he knows what he is teaching!! Although he asks quite questions for homework, it is worth it!! Because all his test is based on his notes and homework. Exams are easy if u see the notes and homework!! He doesn't call the order and he is nice and funny! Take his class he is the best!!

he is really good, i had for math150A and im taking him for 250A he is the best

Mr. Diaz is there to teach adn help you learn math, so he is a little strict but he is super sweet and understanding. I recommend taking Mr. Diaz if you are looking to learn and succeed. :)

This professor was one of the most interesting professors I've had. He notes were easy to follow and he kept his lecture interesting. Homework is a must if you want a good grade. Do the homework, attend class and you should pass no problem.

very easy give alot of extra credit. prints out lecture notes for you to fill in during lecture. test are somewhat easy

Mr. Diaz is a very good teacher. Apparently he has a problem with younger students complaining about his difficulty (might be why he was so mean to our class). The class is Calculus and if you are not savvy in math, sadly it will take some work to get it. That's life though, and you are going to have to work to accomplish anything worthwhile.

Diaz is the best, hands down. If you need to move onto higher math classes, Diaz will make it his duty to make sure you KNOW everything - while making it enjoyable. He explains topics very well. His tests are reasonable, and he will train you to dominate any class ever.

It will take you some time to realize this teacher's worth. At first, he will seem like a real jerk, but he will eventually prove himself. The class isn't necessarily EXTREMELY difficult, but if you don't try hard, he will definitely show you off. Attendance, punctuality, and a passion for math are a must in his class. He's a very good teacher.

Very down to earth. wants you to actually want to be in his class. drops people without warning if you miss days and misses 8 homework assignments. Kind of up and down with his emotions i guess. more of a friend than a professor. homework is all online so he doesnt make you buy the textbook. take him if your not lazy. i was and got a c.

He is very thorough in his notes and nothing unexpected came up on tests. He's a little crazy, but a nice guy who is passionate about math. If you show up and take the time to do the work, he'll like you and you should enjoy the class.

If you like laid back teachers that are nice then hes the one for you. He's very easy going and is very passionate about math. he makes everything clear. If you ask him questions he does his best to explain in way you can understand. Diaz is a good teacher.

if u need any help with math or just need a laugh diaz is your go to guy

This guy is epic. Super helpful, will help you if you go see him. Loves math. Make sure to talk to him about videogames. Dropped one test to replace with the final which saved my grade! I got an A thanks to his help. Couldn't recommend him enough.

Had him for online math 16 and 20.easy going,helpful, course work is not hard at all. drops your 2 lowest test grades. he gets it cause he is young. i recommend him for sure.

Mr. Diaz was very nice. He always signed his emails with "kindest regards." More recently, I had to contact him about something and he remembered me and asked how I was. That may not seem like it has anything to do with his teaching ability, but good teaching starts with caring about your students.

Diaz is really a simple and approachable instructor. He expects a lot from his students and expects meticulousness in his exams.Homework is online and exams are from the notes. Lone thing i disliked about the class was his notes: he transcribed the ex. problems from textbook and redid them in class. Take him if you have the chance.

Book & HW online?do ALL the HW. Tests are hard but doable. Write out the proofs & show ALL your work. Diaz is one of the best teachers I've ever had. He's passionate about math & truly cares about his students. Not an easy class but don't let that discourage you. I hate math but loved this class. Take him & put in the effort?you won't regret it.

awesome! took his math 40 online class. so easy. homework not mandatory, all you had to do were quizzes and tests. you get 3 tries on each test to pass. i suck at math and also super lazy when it comes to it, and i got a c. always responded to my emails. take online!!

Im a skilled math student and not a whiner, but this is the most out of touch professor Ive ever taken. Unreasonable expectations for homework & studying (5+ hr hw). Obsessively meticulous. He needs to remember few of us are math majors and the rest of us (engineers/computer majors) will not be doing calculus by hand in the field. Not recommended.

Diaz is a very straightforward professor. If you work hard you will do well, if you do not do the work, then you won't pass. At least he says from the beginning that it won't be easy and that you will have to spend a lot of time studying. Don't be surprised at 4+hrs of homework a day + study time when each day is like a regular week (Summer class).

Robert is different~ I seldom talk to him but feel he tries to help and encourage his students without words. Tests are not difficult and he grades fair. You can "double" the final to improve your whole grade a lot.I always guess if he is an artist-typed person although he likes to repeat it's hard for him to draw a PERFECT line when graph~

I think his lectures and note sheets are tremendous, however more in class interaction with the students, i.e. letting them try examples while they are still in class, would be beneficial.

Diaz is by the far most the meticulous and competent of FullColl math faculty. I like the fact that he enjoys teaching math (may be a façade) and is approachable. I don?t like his exams. I have picked up a pattern: he plucks problems identical from his class notes and throws them in the exam. I feel this does a disservice to students.

The best Math teacher that I have ever had. He doesn't mess around, if you don't want to learn in his class then don't pick him. Robert will read and the rest is history. So pay attention and LEARN!

Robert Diaz is my all time favorite professor. He is unique which makes class fun! He is more than helpful if you take the time to approach him. Robert knows when you put in the extra effort and it will pay off in the end. The group work helps to so you understand the material and his lecture notes are wonderful! He is adorable and funny

Pretty good teacher he enjoys math and what he does.The class can be pretty hard because theres so much material to cover,but thats only because he knows you have to have a good understanding to move on to Calculus. Tests consist of slightly modified problems from the notes so listen up If you ask, he'll tell you what you need to know for the test.

Professor Diaz seems to enjoy what he teaches and although he has a keen sense of humor and often sidetracks during lectures, he still manages to lecture pretty well. This class is somewhat difficult and you might have to allow more study time than other classes. His tests are usually predictable if you do homework and notes thoroughly.

I've never been really good at math but he explained it in ways that I could understand and would gladly answer questions. He did sidetrack from lectures at times and said some innapropriate jokes but I did learn a lot from him and recommend him. All homework was online so you could try a problem again if you got it wrong the first time (awesome!)

Diaz is great. He types out notes for you and doesn`t grade hw. Your entire grade is based on exams and the final. BUT...he prepares you very well for the exams. He offers extra credit and makes learning fun. Attendance not mandatory. Class is relaxed and enjoyable. He is helpful with questions. Will take again for 250A.

very easy class ! as long as you show up and do your homework you are fine ! ( not a lot of homework) he has horrible jokes that are extremely funny/inappropriate ! He is there to help you and is very good with notes as long as you follow along. TAKE HIM

Diaz really helps you understand math and explains clearly. Tips: ALWAYS do homework, it's online, you can always try again if you get it wrong (easy points!), ALWAYS come to class or you will get dropped, and ALWAYS study for everything throughout the semester because the final is cumulative. If you aren't a math person, take Diaz. He's the best!

Robert is my all time favorite professor. I've always hated math and he made me believe that hating math was a choice. Every time I had a question he answered it. The lessons were to the point and the worksheets he made for us made for really great notes. Ignore the bad reviews TAKE ROBERT.

Great teacher! Straight to the point in lectures, goes over what you need to know for the exams and explain theory. Nothing tricky on the exams, and he is very helpful in office hours. Highly recommended.

Diaz is an AMAZING professor. Goes above & beyond to help students understand calc. Notes are thorough so NEVER miss lecture, & take note of every detail. Exams are very difficult, but possible to complete. Really funny- WARNING: some find his humor off putting. HIGHLY RECOMMEND if you plan on taking higher math. Be prepared to work your butt off!

Really helpful. I missed two tests because I'm so scatterbrained and he actually extended the due dates so I could pass. Honestly, what professor does that? Awesome!

Very passionate. Time consuming work so just start it right when it's assigned and you'll be fine. Tests are pretty easy if you understand what's going on in class. He goes over what will be on the test so write it down and study. Provides textbook online free. Just take notes in class, do homework, study, get help when needed and you'll be fine.

Robert is everything. Without a doubt he loves being a professor. Everyone that is hating on him expected a good grade with little effort. Robert expects your best, and gives credit where credit is due. Taking one of Roberts classes will leave you with more than math skills. I recommend him 100 percent! Take him as many times as you can!

It's easy if you do the homework. Lectures can get slow, but he wasn't bad. He's the type that shows interest in the course his own way. Try to talk to him.

I hate math and this was the best classes I've taken at FC. I really wish I could have taken more classes with him. He is very clear in class on what he expects and will show you shortcuts. I struggle with math and came out with a B at the end of the semester.

Robert Diaz is a great professor for the math department. His notes packet really helps student in understanding the lecture. Very brilliant and loves his job. BUT he is definitely a weeder professor. Very hard grading. Makes you work for it, but all in all he's a great professor. Recommended if you take school seriously.

Overall he's a good guy who really does have good intentions. He's quirky, funny, and really chill about stuff. If you have any questions, you raise your hand and he'll explain to you to his best of his ability. Typically he does a good job in explaining, but sometimes he can kind of confuse you. If you use MyStatLab, it comes with the textbook.

He is not a bad guy. He gets off topic at times and he is such a dork. He gets mad at himself and embarrasses himself which actually made the class a bit more funnier. He does offer help actually just go to his office hours he will help! I would not take stats ever again, for me it was a bit hard, but I pulled through. Good teacher.

Really great class, Diaz explains the material thoroughly and clearly. You'll work hard for your grade, but it will be worth it. Homework isn't gone over in class but he is willing to help in office hours. He likes to joke in class, though his humor is a bit random. Maybe not for everyone, but one of the best math teachers I've ever had.

Prof. Diaz is a very helpful either inside and outside the class. You need to approach him. You have to do each homework practice in the math lab and you will be fine. I got A in each of the exams because I practiced all the questions he gave us to practiced.

All of those looking for Easy A's, he's the one you're looking for honestly. What I suggest is doing a problem or two each homework. I would do the first couple of chapters since they're the easiest. The first two exams were at home. He drops the lowest one. You can write a whole cheat sheet. I got a B but literally did nothing towards this class.

The best math teacher I ever had. He walks you through every step and if you have a problem he will always help.

Teacher gives long-winded lectures that are quite frankly boring. There are three tests that will make or break your grade, I found the first to be the hardest. The class is tough but I found it to be fun being that I enjoy math. Everything is online so access to a computer is important. Don't take the class if you aren't motivated to pass.

He really wants to make sure that everyone passes but it was an online hybrid class that was unconventional because we still had a very helpful lecture on Fridays. He has office hours and if you never show up to class it will get harder over time. if someone failed his class it's because they stopped coming to class once a week. He is available too

Great professor, explains and lectures well. Funny and let's you use notes on test. Gives estra credit as well. I've always struggled with math but in his class I did great, teachers do make a difference.

He understand not everyone is a math major and makes math easy for everyone. Has weeks built in semester to catch up, really wanted everyone to pass. He really asks for the bare minimum. You can use cheat sheet for exams and he uploads textbook to canvas/no homework so you dont need to buy anything. Super caring. Highly-HIGHLY recommend

One of the best professors I have taken. It was an online math class due to the pandemic, but he really helped his students pass. If the student did not pass, it was due to not doing any homework, reading the textbook, or just staying stagnant. Homework was not turned in or graded, which I really liked because it was less stressful + learned more.

I really liked taking this class with professor Diaz. Grading, homework and tests were right to the point and at your own pace before the deadline. There is a lot of homework, but like I said, just do them earlier!

Professor Diaz is an amazing professor of probability and statistics. He uses a software name r studio and it is not for everyone but it's very easy if you practice it more. He is understanding and makes math easy for students. Our final was a group project easy A in his class. Take his homework is only two assignments per week.

Provides note packets each chapter that show you exactly how things work. He likes to use R Studio which will do any statistical problems for you if you follow the packet instructions. He's a goofy guy, and you can tell how much he cares about his students. We had one in person exam, an online exam with unlimited retakes, and a final group project.

Took him in-person for Trigonometry. Make sure your math skills from previous classes are not rusty. Homework is very light; however, he places a clear emphasis on making it look neat and with proper notation, formatting, and neatness. Don't be afraid to correct him or ask politely for clarification if he makes mistakes in lectures or notes.

Took him for my stats class and passed easily, he is super nice and seems like a quiet person but is very knowledgable of what he teaches. Everything is on the projector and board that needs to be done so nothing is confusing at all, it's pretty simple. He also makes jokes and is just a nice person to talk to, please take him to pass math!

Professor Diaz has a unique teaching style that takes some getting used to. The R Studio software can be tricky, but the note packets are very helpful. With practice and using Unstuck ai for study prep, the class is manageable.

Professor Diaz was great! I took 120 online over Winter Intersession. The quick pace was a challenge, but having a friendly professor made it a lot more pleasant. He cares and was very personable. The course was well organized and the grading criteria was clear and fair. Pro tip: check out a calculator for free from the campus library.

It's easy to get lost during lecture because he goes examples and proofs quickly. But he is a great professor that clearly wants you to succeed. Expects you to give it your all, will call you out if you don't. He would also highlight the sections in our math handouts that will be on the test. Lots of HW. He's not for everyone though.

Was extremely caring, I struggled a lot in his class, but he was always available to help. He curved the exams which made it easier to pass.
