He is not hard, but he is unfair and bias. He wrongfully took off 5 points off an exam, and would not give me the points due to his error. To me, flashing a book on a screen is not teaching. He acknowledged that cheating was occuring in class, and did nothing. There were a lot people cheting

Very BAD professor

Even by mistake,don't ever take his class. He gives exams which are really tough..

If you have him change class, he knows his stuff but does not teach it well, does not know how to help or explain things or concepts to you. For this proffessor you need to do your own work, read the whole chapters your self. He is not good at his job at all. You see him teaching go the other way!!!

He is the worst most uncaring teacher I ever had- half the class withdrew and then 1/3 of the remainder failed. I got a D! and I got A's in all my other Chemistry classes! I had to transfer to another school to pass the freaking class. I srongly recommend NOT taking this class woth Alva- he is AWFUL!!!!

he is by far the worst professor ever. he never answers any questions that u need help with. and he tells me what im not doing in lab while i AM doing it, so i had to tell him off several times. his exams are very difficult and he tells us he went over it while he never taught it to us. He seriously CANNOT teach. no joke. he might know his stuff, b

cannot believe he was allowed to teach such a difficult class and not be able to teach it. it is so unfair to students who want to learn.

I strongly advise you not to take this professor. He just reads a summarized version of the chapter and he never wants to answer any questions never goes over formulas he does grade on a curb but he has to cause he doesn't teach. I passed the class but i didn't learn anything...

He is the worse of the worst! He sucks! I can't stand him! He is mean. He is not in favor of the students. He seems to get a kick out of failing students. DO NOT TAKE HIM! you will regret it. somebody told me not to take him, but I didn't listen. He even laughed at the class for taking him during the summer.

I did pass the class with a good grade but still say he is the worse professor in the world. He seems to be concerned but he is not. he does not grade the test fully always missing points. He doesnt go over nothing. you will be teaching yourself. DO NOT TAKE HIM! luckily i didn't work or else i would have been in trouble. He is the pits!

USELESS

Just like everyone before me stated "WORST PROFESSOR IN HISTORY". How or why he is a professor baffles me. He has no social skills, he hates students, and he obviously hates teaching. I hope BMCC reads these comments and give him no student contact. I avg a 95 on his exams got a 85 on the final and he gave me a B because I missed a lab !!!

I got an A in his class by my own determination. Read the text....I truly take credit for teaching myself chemistry because he is not helpful at all.

He gave us the first test back yesterday, 70% failed, and the class average is 53%. He is a murder in taking out points with no mercy. I had to withdraw from his class. My GPA is 4.0 , but I was afraid of getting a C or D in his class. Honestly, do not even think about him

you dont want this!!

DO NOT take this prof. He speaks Spanglish and is difficult to understand. I had to withdraw from his class. He is very vague and teaches you like you should already know the work. There is a different lab prof. who gives you a quiz on experiments you haven't done yet - which is part of your overall grade. DO NOT TAKE THIS CLASS!!!!!!!!

Register for this class only if you're prepared to teach yourself the course from start to finish. Alva's class notes consist only of figures that he's copied and pasted right out of the textbook. He doesn't explain ANYTHING and rants on and on about how students complain about their grades yet he can't see that his lack of teaching is a direct ca

this professor is useless, pleasse do not take his class if you have another option. he teaches nothing and expect you to teach yourself. he doesnt take his time to explain things in class. i will never advice anyone to take his class

Horrible teacher. If you have questions he will just brush you off. You need to teach yourself. Don't waste a semester!!!

if you are willing to teach yourself, take his class. if not don't even try because you will not learn anything from him. he will simply read( not explain) his powerpoint slide.

I'm currently in his class and I have decided to write this as a warning. This man in someway has impacted me in a negative way. He is rude and demeaning. He talks to his students as if they were animals. He is bias toward the students he feels are not capable. If you do not have to take him please don't.

I don't think he means to be rude, but he can be very demeaning. He is into posting grades in front of the class and if someone knows your grade do you know how embarrassing that is. He is not fun to talk to if you let him get to you he can be nerve wrecking. If you have another choice for org choose someone else.

Prof like Carlos needs to understand that being a tough prof is not synonomous with being a good prof. A good prof sees that the class is struggling and does something about it. A good prof sees that when its the WHOLE class complaining maybe he's the problem. This is not the type of subject where one is expected to know EVERYTHING Understand that!

First, I would not recommend this prof to anyone. I know this is a tough course for everyone but clearly he doesnt do his job. When students ask him how the test looks like, he always answers do the problems from the textbook. However, his lecture(powerpoint) is the same as the textbook. He only cover few of them.

Wash time & money!!!!

This professor is upfront on the 1st day of class, if you do not read the text book you will not pass. The exam questions are from the text however his teaching style is the issue he only reads from the powerpoint never reviews the different style of the questions unless you ask him. Stay away guys!!

DO not ask a question because he will ask you the same question back. He wants you to think for yourself . And don't ever think he doesn't see or hear you because he does! Your work must be on point at all times no mistakes for him. Good Luck

Horrible professor. He hates to answer questions. He just reads off of the PowerPoint slides ,and his study guide is unclear.

The worst professor at bmcc. He just sits in class and reads off the powerpoint presentation. He is not helpful at all and gets annoyed when students ask him any questions.

You basically do all of the work yourself. He is extremely rude and demeaning and absolutely hates to explain the material properly to students.

The absolute worst. He is very rude and condescending.

Terrible experience. You are basically your own professor.

please don't take him if you want to get good grade !!!!!

He hates to give any explanation in the lab. He just runs through and reads the powerpoint with no explanation. Be prepared to do all of the work yourself.

The worst. Do not take him if you have other options.

Horrible. Alva just does not care.

The labs are the worst. He doesn't explain the theory behind experiments at all. He expects u to know everything by yourself. He writes nothing on the board, just handouts. It's very difficult to assemble equipments and understand the theory without the help of ur Professor. This Prof. just leaves u there hanging. U understand nothing at the end.

I took this professor during the summer . Professor went too fast and was annoyed when you asked him questions. Does not answer emails and doesnt not help you outside of class . DO NOT TAKE THIS PROFESSOR.

Horrible professor. Do your self a favor and dont go through this. Reads through powerpoint, makes fun of people in the class, discourages people in the class. Cant answer questions idk if he is professor or he is just there to make money. You can study this class from youtube on ur own. Taking his class waste of your money and time.

Very bad attitude. Doesn't know how to teach. Save your GPA

Horrible Professor who doesnt know how teach. He ruined my gpa. Avoid his class

This professor is the most difficult one in the department. His exams are very difficult. You also have to teach yourself. Avoid his class if you care about your GPA

Avoid and run from this professor. Very tough exams and tough grader. He's not flexible a all.

You might as well teach yourself. Professor Alva doesn't care for the students' performance. He expects you to know everything just after one lecture. Don't take him if you wan't to keep a good gpa.

The lectures were long and you need to create your own study guide because the practice test did not consisted of any tests.

-verryyyy insulting and harsh when you ask ques. RUDE! -you're teaching yourself, just reads/ rushes thru lectures -TOUGH grader, and barely any assignments sooo you need a good grade on the little he assigns to get a great final grade -careless asf -Has a heavy accent -Terrible explainer -HAVE to know the coursework VERBATUM before going 2 him

I had to drop the class mid semester. He is very racist. Made a comment of two people from different country that they all look alike AKA Chinese. Do not bothered asking him any question because he wont answer. Very hard to understand what he is saying. He's exam reviews are not helpful ATALL.

I would like all of you students to know that the test book chapters won't help you in the exams.There are no review before exams.He has a very poor practice test which consist of only 10 questions that are not related to exams at all. He just reads his slides in a monologue in the lecture and doesn't help during the lab. Doesn't answer questions.

As it was a summer class, I went in knowing it was going to tough. However, I was not expecting to have to teach myself all the material. He is not available outside of class as he's "too busy" - no office hours and does not respond to emails. Lecture sounds like he is talking to himself rather than actively trying to teach the class to understand.

Prepare to not be actually taught material and then be berated that you don't understand. His slides are just images from the textbook with no context and he does not actually teach.Don't take in summer, not enough time to teach yourself. Grades are just based on exams and lab.

Do not take him no matter what. He is the worst professor I have ever had. Very rude to everyone and cannot teach to save his life. The only people who are passing the class are those who are taking it for the third time. Save your time and do not deal with him. I do not know why he still has a job.

You could not pay me to retake that class. By the time of the final there was only 5 people left. I am not sure how he has a job. The worst professor I have ever had in my life. Can not teach and expects you to know everything already.

This is the first time I am rating a professor just to tell you how awful he is. The only lessons he provides are reading off the powerpoint,he takes offense to people asking questions and the only determining factors are labs (16%) and exams make up the rest To top it off the lessons are not even relevant to the exams themselves Avoid at all costs

This is my first time eating a professor just to tell you how awful he is The only "lessons" he gives is reading the PowerPoint and he takes offense if you ask any questions to top it off 84% of your grade is made up by tests and the PowerPoint is not relevant to the exam content. Avoid this professor at all costs or you will commit gpa suicide.

This is my first time eating a professor just to tell you how awful he is. His idea of lessons is just reading the PowerPoint and he takes offense if you ask questions. To top that off the only real determining factor of your grades, exams (make up 86%) have content hat will literally never be discussed in class. Avoid at all costs.

He is a very tough grader. I would recommend you teach yourself and go to tutoring. He does not give resources, he just teaches the PowerPoints in class only. It was also hard for me to take notes because he jumps from slide to slide. Worst teacher for a hard course like this

I took this guy years ago-on the 1st day, states he failed Organic Chemistry twice. Refused to answer any questions during office hours or during class + openly mocked students for asking a question. Made disparaging comments how private school kids are taking this class at BMCC to take advantage of the system. Surprised he's still allowed to teach
