worst teacher i ever had

Get yourself a tutor and a huge box of Midol... for him. "Friends don't let friends vote Democratic." ~ Alcan'tteach

This guy is a terrible teacher.

He's a monster! Geez, LOUISE! Where do I start? From working too fast, to giving snide remarks to students when they have questions about the material he just RAN OVER. He's a monster...

when i had him he would rather talk about the acid rumors about him, and politics than teach, and when he did teach he went soo fast you couldn't catch everything that was said.

can't teach, hes to smart for his own good, take it at another school if possible, oh ya and right-wing politics for your enjoyment.

He expects you to know everything, without actually knowing what you know until you fail his tests

This was the worst teacher I have ever had, ever! He hates explaining things- the worst at helping you understand. He'd rather talk about politics and any other thing. He's pompous, brash, and offensive. There are much, much better math teachers to take, I promise!

He is absolutely the HARDEST math teacher I have ever had in my entire life. I have a B.A. in Math and his 173 class is the only class I have ever failed. Even upper division math classes are easier than his. Don't ever take him for any class, especialy Math 90. Very Very hard. Very Very VERY HARD.....do you get my point???

Dan is a cool guy in and outside of class, however, he does have a bad time with talking over everyone. He will constantly repeat "you should know from math 70" which gets annoying. If ur not a math major, dont take him!

He was the worst teacher I have ever had in my life. He made me feel like a complete idiot. I feel like I can't finish college because of him. I'm not kidding.

What a complete closed minded freak of an ****......you idiots that actually said he was a good teacher must be his S.I. representatives. LOSERS! -TEACH, DON'T PREACH!!!!!!

I can not believe that this man is teaching. He is rude, condescending, a vain (in the math sense). If you can not pick up math from the text book you might as well drop him. He doesn't give very many quizzes if at all and his exams are crazy (he wants you to derive the formulas you need to work the problem) AVOID LIKE THE PLAGU!!!

This guy is crazy. He teachers like we all have master degees in math like him. He gets off track really easily too. If you ask a question, he makes you feel dumb. If you a democrat and easily offended, dont take his class either. (i thought he was very funny though)

WOW! This guy is hard and annoying!!! He has terrible lesson plans b/c he starts out with a section and ends up talking about another math class all together. He loves math 122 becaus thats all he talks about in math 90. You can't understand him when he explains the math lesson you have to go home and read the section to get it!

No explanations./Ask a question and this instructor make you feel retarded!!

DO NOT TAKE THIS TEACHER..LECTURES NOT CLEAR..HE TOLD THE CLASS I WAS IN IF WE DONT PASS MATH 70 WITH HIM WE SHOULDNT EVEN BE IN COLLEGE BECAUSE EASY...NICE WAY OF CALLING US STUPID

He is very hard but a genious.

No comment. But i will say that he is pretty helpless.

i usually do not rate a professor, but this guy made me to. i TUTOR math up to 172. I am failing his class with an F. this is while i have an A in both math 171 and 172 (the hardest Cal between 171_174) with j. Johnson (the hardest Inst.) the poblem is this guy teaches from book, ignore the entire class, but his tests are impossible, terribely hard

Mr. Alcantra knows a lot. he has been doing this for 22 years. But when i sit in his class i would rather to gain some of his knowelage throughout the semester; i couldnt. his test is out from space. there is no connection between his lectures or H.W, and his tests. he is the only 173 inst. for other classes you are crazy if you take him, period!!!

So I read these comments before i registered for his class and I did NOT want to take his math 70 class, but I had no other choice. My plan was to just try my hardest but that didnt work. His tests are from outter space, lectures dont make sense, and doesnt collect homework. Dont take his class!! He is by far the worst teacher i have had.

This is by far te worst instructor ever. If you take his class, then you are pretty stupid. He never collects any homework and seems to get pissed off if a student keeps asking questions. if you want to fail, then take his class. He also always looked out the window when he came into class and came to class with his zipper down. NEVER take his clas

Funny Guy but only has 4 tests, dose not collect homework, no extra credit and tests cover 2-3 chapters. Each chapter has 4-8 sections. Does not explain material well, solves problems in his head without showing steps, tests unlike the homework.

Danny Boy aka Baby D is not the best math teacher. He always glared outside the window as he solved math problems in his head. He walked in with his zipper down and made jokes about democrats and Nancy Polosy. If you want a good laugh take his class. If you want to understand the material and move up to math 90 don't take this class.

Took him and regret it. Got an A in math 70 and only passed with a C because I had to spend hours studying the book and teaching myself. His lectures are useless, I never learned anything. He gets many of the problems wrong himself and his notes are very disorganized.

this guy is HORRIBLE, i hate his class. talk about crap a lottt. he does take attendence. after 2 month in his class i figure out y he take attendence because he know that students will not go to his class so he take roll to force student to come to class. i notice there a few good comment about him on here but i believe it himself who put that com

No matter what, don't take this teacher for Math 173. His notes are extremely unorganized. Not helpful at all as to when certain methods should be used. Very poor teacher on a difficult subject.

I constantly wonder whether he likes to teach or not. Doesn't grade homework which only has me wondering where I stand and unsure of my skills until test time. Not allowing us to see where are skills are and where they lack before a test is only hurting the student. He seems lazy and uncaring. Do yourself a favor and take someone who cares.

Dan alcantra is good at math, but he hates math 70 it seems to be too easy for him. He runs through the material with no homework checks and when we finished our 2nd test he told us that there were only 4 test. I would not recommend anyone to take his class because he does not care about his students at all our half class dropped

I have had a bad experience with teachers but not even close to this teacher I took math 70 with him just this January 2014 for spring and oh my he makes you do hw everyday and he doesn't correct or collect it, you will never know if your doing your hw right or wrong. he only grades you on 4 test and a final worst teacher ever.

Probably one of the worst prof. He would ramble on and on about a homework question, taking up to 10 mins, then once he explains how to do it a different way he would say not to worry that he would cover that later on in the semester. There he would waste half of class time, By the end of class I left confused and like I did not learn a thing.

Alcantra is a really difficult teacher. He expects you to know how to do the math, for example he expects you to remember the work from math 70. When doing example a lot of the time he'll do parts of it in his head which may cause problems if you don't understand. He assigns homework but doesn't, he only grades tests. I would not recommend him.

Not a good teacher at all. Not helpful. If you struggle with math in any way or aren't too confident, don't choose him. The only credit you earn is through tests and they are very hard. Overall he's not a good teacher at all.

This is by far the worst teacher I have ever had its not even close. I am a math major whose transcript is literally all a's until this class and then a's after literally the only b ive gotten and it was a close b. He disrespects the entire class every class always has time to complain about Obama but never time to go over a hw problem.

Different teachers have different teaching styles; his wasn't for me. I'm mostly here to warn that he LOVED to go off topic; he frequently went on tangents and they were often political (specifically his hatred of H Clinton); it probably didn't help that I took his class during election season, but just a warning.

Lectures arent clear, takes a very long time explaining. Makes lectures very confusing when they could be simplified.

He constantly talks off topic to state how much smarter he is. I get it, you're a math major. Also he constantly shares his political opinion about how Hillary is a terrible person. He rarely actually teaches the material, he just answers homework questions. He whines about student's leaving on time while he goes over constantly. Terrible teacher

He spends half the lecture answering homework questions and the other half of the lecture complaining about millennials wanting free education while bragging about how he only paid a $5 fee when we went to CC while barely covering the math. He gets very political too. His tests are extremely hard. He gives out homework but it isn't graded.

One of the worst professors Ive taken at Mjc. He does a lot of math in his head and doesnt even do it step by step. Wastes time ranting about random things and goes off topic, and gets upset if you ask a question because he expects you to know it already. Be prepared for tests as well.

Worst prof I've ever had. If you want to do well you need to have all of calculus memorized off the top of your head. Extremely political and unprofessional. His reputation is true, you are better off not taking him, or dropping and taking it somewhere else. For reference I got a high B in Calc1 and 2. This class with him is not worth the stress.

Honestly the worst professor at MJC. Makes you feel bad for not remembering things from algebra and trig classes that were taken long before calc 3. His tests are RIDICULOUSLY hard, no correlation to the homework. Talks about politics a lot. Overall, terrible professor. Do not recommend unless you enjoy suffering.

TERRIBLE PROFESSOR. Thats all I have to say

Do not make the same mistake I did by taking this class. Unless your a math major/genius he could care less about you. Grading was totally unclear. I got a pt. higher for getting concept right vs. someone who didn't answer on an exam. Take math elsewhere unless you're a genius. Nobody cares about what Margaret Thatcher had to say about socialism!

Dan is a friendly guy and a lenient grader. It won't help you. The exams are really tough, and that's all he grades. He's also a very proud conservative, and he will make offensive remarks without reserve. I wish he didn't spend half his class talking about politics or Adam (who came here LEGALLY). He will humiliate you with irrelevant quizzes.

This was the worst teacher I have ever had. He frequently went off-topic, going on tangents about how much he hates liberals, telling jokes about minorities, and his personal life. His lectures are just plain confusing and I only passed because of the book, I learned EVERYTHING from the book and nothing from him.

If this is your only choice for a professor, just dont take the class. Please save your time and hope for an earlier registration date to choose anyone except this professor. I did all the homework and showed up to every single class and tutoring and still failed. He blames the students for not passing! He is rude and just doesnt care if you fail

You will barely pass this class. I was a 4.0 college student until this class, I have put in more than enough hours to pass this class but yet I'm still barely passing this class. Go take calc at Merced community college and not this college. I taught myself everything this semester and even stopped taking notes on the lecture. Grade is 100% tests.

This is the worst professor I have had thus far. He only grades exams, which is understandable, but his exams are too difficult and can't even be compared to the homework. It's like swimming in a pool and then trying to swim up a waterfall. Also, his lectures are disorientating. He doesn't organize his notes well either.

I heard many peers talk about how terrible of a professor he is, and I was naïve enough to ignore the warnings and take his class. His lecture are completely disorienting with no direction. He goes off the top of his head and does not care if students are following along. Grade is 100% based on tests and he chooses the conceptually difficult ones.

If you're enrolled now, drop him and don't look back. Lectures are for people who already know material, he grades based on if he thinks you're an A/B/C/D student. Allows his prejudices to come out and does not care to help. He's an awful professor who shows off instead of lecturing. RUN. DON'T. WALK. FROM HIS CLASS. You've been warned.

Let me start my saying math is far from my strongest subject, however he hardly taught us and if we needed help he told us to watch videos we find on YouTube. He would post another professors lectures instead of making his own. He expected us to know the material before teaching it. He would bring up the election every class instead of teaching.

Probably the worst professor I've taken so far in my college career. As someone who grew up loving math and science Alcantra made me hate it. Class is excessively hard and you will have to teach yourself EVERYTHING. One thing I can say is this was during COVID so maybe he's better in person. I went to a different college to avoid taking him again.

His lectures are poor. His test are ridiculously hard for no reason, (meant to fail) and I would know because I took ap calculus in high school got an a+ for calc one and two, and passed the ap test. Also, all he talks about is how we dont know anything because of common core and brings up his political beliefs in the middle of lectures.

Absolutely terrible terrible teacher. Tries to teach you about a subject in a way he would explain it to someone who already knew what he was talking about. His teaching style is disjointed and confusing and makes literally no sense. However, if you make it out of his class with an A, you can consider yourself HIGHLY proficient.

If you have a knack for watching a professor ramble on about theory for an hour in the morning from monday to thursday this is the class for you. If you want to read the entire textbook by yourself without any worthwhile explanations by your teacher than this is the class for you.

I regretted it every single minute.He does not care if we follow lectures.There is no place to get help. If you ask him anything it ends with him saying irrelevant views about politics how he used to do things back in the day.He gives lectures on paper and I had to see his hand throughout the semester. In his head, he is still living in the 1900s.

Does not teach any material whatsoever. You will be learning everything from either the textbook or youtube. Test questions include the most difficult questions he could ask. When asking a question, instead of explaining it he will just do the problem and assume you can figure out the rest.
