Lets face it, Physical chemistry can be hard. If you show some interst and make an effort he'll do the same with you.

Material is beyond most peoples capacity, unfortunately they take that out on him by giving bad ratings. I never saw him try to "humilize" anyone but some people "humilized" themselves. Slides are cluttered but make sense if you read

He is a good teacher. Some of us try to blame our professors for our misery. You need to read.

May sometimes ask ambiguous questions. Expects you to go beyond what is in the book (so get a another quantum text). Tests aren't that bad if you do the PROBLEMS in the Atkins text and DO THE PROBLEMS HE SUGGESTS. Look out for trick questions.

Students have a hard time in this class with him because he is so hot and charming that one cannot concentrate in class, Believe me!

Dr. Hernandez is the best teacher WE'VE ever had. Cares A LOT about students always has time for us. It is a difficult class and he has a great sense of humor to make it bearable. Bad students blame the professor for their bad grades so all those other comments are WRONG!!!!!!! He is also VERY hot!

Very good at teaching complicated materials in an easier way. Tests are hard!! So prepare ahead of time. Usually very helpful at the officehours. Help students that are serious and eager to learn.

Great Teacher!! Very Hard tests beacause the material is tough but follow his guidelines and you will survive. All the best!

While he's hard he's fair, when he has designated time to help you he helps, fairly tough grader, if you're looking for an easy grade def not the professor for you. You will learn if you apply yourself, he's not giving anything to you, except the tools you need to succeed; you have to earn iwhat you want.

Wonderful professor who brings clarity to a hard subject such as PCHEM I.

The professor is very interested in making sure you learn the material and not just go for the heck of it but by doing so can make chemistry a little more confusing. However, I think hes fair as long as you read the book and do some quizzes in the textbook website youll do fine. I got a 87 in the class but with the curve a 96

I took PCHM Lab with Dr. Hernandez and I found out he is not bad as the other students think. He is the best professor so far I have in UCF. If you listen careful what he said you will be find. Yes, he is very hard, but even if you have 'C' in his class is paid off.If you take his classes be ready to study hard. Best professor.

Definitely need to study for this class and attending class really helps. He gives you his power point notes but reviews everything the day before the test. He genuinely cares about your learning and tries to help you.

This professor is great. He truly tries to teach you something so that you learn it, not so that you can just forget about it after class. He has a bit of an accent, which makes his stories even funnier. Every time I have a question, he is willing to sit with me for an hour after class until I completely understand. I recommend him very much.

For a lower level chemistry class, I found it more difficult than it should've been. Although I take most of the blame for not studying thoroughly. The professor truly cares for your learning however the class grade comprises of only test grades. To pass his class, first attend it then practice as many problems out of the textbook as possible!

This class is not easy, and I don't recommend to anyone who isn't a strong test taker. He cares a lot about the students and clearly enjoys teaching. He is fair when it comes to curves. Make sure you study heavily, and know the material very well. Test questions come from the problems in the back of the book, usually the harder problems. I got an A

Not an easy class by any means, but it's chemistry and this is college. Worked very hard and ended up with a high B in the class. He is a nice guy and does care about his students. he is nice if you go see him during office hours. and his accent isn't bad at all...some people are just uncultured. study hard and you can pass. taking him for 2041.

Chem is never easy but it is only chem 1 so it will get harder. He means well but does not fully deliver. Luckily, he is constantly adjusting towards improving his teaching style. Best advice: Do the problems in the end of each chapter and rework the problems done in class. If he even mentions a problem... DO IT! Large study groups NOT recommended.

He is a good professor and really does care about his students. He is really nice and helpful during office hours, so don't hesitate to go see him! Go to class, read the book, do the chapter questions, go to SI.I got an A in this class. Wish he was teaching 2046!

go to class. read the book. STUDY!!!! he is a good professor. I really wish he was teaching chm 2046. cares about his students and wants you to do well! buy the book, even if it's an old edition.

This prof. is really nice and cares for his students, great teacher. Only problem is his tests will blow you out of the water. Take notes do the book work, try for a B.

Chemistry is EXTREMELY DIFFICULT. He really does care a lot about his students and his grading scale makes it easier to pass his class. You will have a difficult time but if you take initiative and practice problems in your textbook, you'll do fine.

Very easy class. Many people who argue that it is hard, do not study. A lot of the questions on the tests are from the book with different numbers. Just study all the problems in the back and make sure you can solve it fast, then you will receive an A. I made a "D" in Chemistry in High School. In other words, just do what he says and "Study Hard!"

Tests are VERY hard. has an accent, but it's not too thick. all the slides are posted online, but they don't transfer well and the text is layered and hard to read. only 3 tests and a final make up your grade. and the 3rd test is 2 days before your final.

It is easy to see that Dr. Hernandez really likes chemistry, but if you want to get an A in this class you better put your social and other academic life on hold because his tests are short and difficult. He curves everything except for the A's (75-89% is a B, 60-74% is a C).

Very energetic and exiting teacher, sticks to his guidelines but is very straightforward. Don't expect to get a good grade with 0 effort, but it is not that difficult to pass. Otherwise I had a great time in the class.

Chemistry is a tough class, but Dr. Hernandez really cares about his students. You will have to work to get an A, but he is a very enjoyable professor to have. I recommend him.

Passionate. If I could describe him in one word... like others have said chemistry is tough and you need to do more than memorize. You have to apply yourself, Dr. Hernandez does care for his students and make it easier to pay attention through his energetic personality. I would recommend him!

Hernandez is great. I came in terrified because of these reviews but overall I have zero complaints. The material isn't that bad and he's always willing to help. However you NEED to put the work in. Go to SARC even. You'll get out what you put in

Read the book, understand the concepts and solve as many problems as you can. Understanding and practicing are key. He is good. It's not easy to get an A in his class but if you do, you deserve it.

Dr. Hernandez is a nice guy and give enjoyable lectures. His test can be a bit difficult, but passing should be too hard with diligent study.

Very Hard Tests. On the other hand he was a very approachable professor that was willing to help during office hours. I personally didn't like the grading scale, even though it was a huge curve for a C or a B

His class was one of the hardest I ever took, but that's only because we were required to actually know everything about the subjects and not just enough to get by. So I learned A LOT! Isn't that why we go to college anyway? To learn.. Take him as a professor and you may be stressed but it will absolutely make you the best student you can be!

Only four grades all semester, all tests. He is a good professor and helps out if you ask him about something on his Twitter page. Humorous, open to questions in class, stops and asks if everybody understands after each concept--overall a great professor. Tests are ridiculously short, though, so every point counts. Go to class and study every day.

Professor is very passionate about what he teaches. He makes it easy for you to understand the concepts. The tests are very hard, be prepared to study very hard.

Nice and funny, but not the best teacher. No homework or quizzes to check how well you understand the material. You basically teach yourself-- and to be honest, you're your own worst teacher. Would not recommend even though he's pretty funny.

He tried his best to teach everyone but he went to fast. I basically had to teach myself this semester. Youtube videos helped a lot. Definitely need the book. REALLY hard test. He claims he solves the problems on the test and multiplies the time by 5 and that's how he knows how much to put on the test. Good thing is the curve. Saved me big time.

He is great teacher. Super nice guy. I took chemistry though and the class does take effort. Based on his skills alone he's a great teacher but if you want to pass the class with a good grade you have to put in a decent amount of effort

Professor Hernandez Is one of the best professors that I have ever taking. the tests are a little difficult only if you weren't as prepared as you thought you were! Study hard and you can get an A. He is a Great professor and has no problem staying after with you are helping you in his office. He will go over every test with you if you want!

Very good professor! Really cares about his students and will go the extra mile to explain something to you. Class is difficult, yet manageable. All of your grades come from the 4 tests, but if you study and do the practice problems at the end of the book you should be fine. Overall great professor and makes this class interesting.

He's a cool guy. Chemistry is a hard subject but if you go to class, do the optional homework, and ask questions its not too difficult. The only thing I didn't like this class was that the final was cumulative, we didn't have a study guide, or even a review day in class. Definitely a teach yourself or get tutored kind of thing.

I really enjoyed professor Hernandez. I have had trouble with chemistry in the past, and this summer, in only 6 weeks, professor Hernandez not only made chemistry easier for me to understand but fun. He's funny, and really cares about his students. All you have to do is go to class, study the textbook, do the problems and you'll get an A.

I really enjoyed professor Hernandez. I have had trouble with chemistry in the past, and this summer, in only 6 weeks, professor Hernandez not only made chemistry easier for me to understand but fun. He's funny, and really cares about his students. To achieve an A you have to go to class, read the textbook, study a lot, and do the problems.

Pay attention to lectures and ask questions if you have them! Professor Hernandez is very helpful and thorough with his lectures. He doesn't assign homework, so it's up to you to check your understanding. Tests are short, so every point is important. I really enjoyed this class.

Professor Hernandez is a good professor. I would definitely take his class again. He cares if you learn and tries to make chemistry understandable. His tests are straightforward and fair. It's up to you put in the work to understand the material but Hernandez helps as much as he can.

Professor Hernandez is an excellent teacher. As an adult in college, be prepared to study and show up to class. His lectures are challenging but insightful. His explanations are genius and his metaphors challenge your perspective on the world. You will learn more than just chemistry with this professor.

First off, I got a C+ in CHM 2040. I was so worried over this class. However, Dr. Hernandez is an amazing teacher. His explanations are very helpful for someone like me, who doesn't understand chemistry naturally. You must show up to class, but he makes it worth it. Read the chapter and STUDY. You will get an A. His extra credit book was great.

Professor Hernandez is very helpful. key: GO TO CLASS. His only grades are the tests, but if you listen to what he emphasizes and do the practice problems you will do fine. I got an A in the class. his exams are not difficult but he wants you to THINK so don't rush. I enjoyed his teacher far more than my previous chem professor.

I'm so glad I took Dr. Hernandez for this class. Chemistry is definitely not my strong subject, but his methods of explaining were very clear, intriguing, visual, and helped me to fully understand the concepts. He's a good lecturer, so make sure you go to class. All it takes to do well in his class is effort on your part.

Dr. Hernandez is an amazing professor who truly is interested in helping his students learn how to think rather than what to memorize; he enjoys making sure you understand why the material is the way it is, rather than stating what to simply memorize. He fit my learning style 100% and I'd recommend him to anyone.

Professor Hernandez is an intelligent man with a lot of passion for the subject. I found him completely credible and always looked forward to attending class. He always delivered lecture with a lot of enthusiasm and was great at making a difficult subject understandable. I would have earned an A if I put more time towards studying!

Dr. Hernandez is one of the best professors i have taken. The material is hard but he gives plenty of examples. He is very passionate about chemistry and is always willing to stay after class to help you for a few extra minutes. Take him if you actually want to learn! He is awesome!!

At first, he comes off as a very serious and "stand-offish" but give it time. His amazing talent of conveying the chemistry knowledge will be obvious very soon. He is truly one of the best professors ever. KEEP your phone away. Practice practice practice the book problems.

Not an easy class, but the teacher does everything he can to help you out. If you study and put in the work you will pass.

Great teacher helps out a lot! Lectures are helpful but if your a self-motivated person then you probably won't need to go to the lectures. Book is unneccesary since the lecture powerpoints (from Google Drive) come from the book directly. Only 4 tests but each test has an extra credit question. Have about 3 weeks between each test.

Let's face it, gen ed chem 1 is not going to be an easy class. To do well in this class, you are really going to have to want it. I found myself teaching most of the material to myself. READ THE BOOK BEFORE LECTURE. If you do all of the problems by topic in the book, you will find his tests to be very fair (he uses exact questions from textbook).

Hernandez is the best professor you will ever have. Don't expect to go to lecture and absorb the material. Get out that clunky book, try to work out problems and if it's still all confusing, GO TO HIS OFFICE HOURS. In fact, just go to his office regardless, he's the coolest guy and will help you achieve more than an A in chm ib.

Dr. Hernandez is a great professor. He makes it clear for you to understand, he does have a bit of an but it isn't a great language barrier. He will make you work for your grade, but he is there to help during office hours all the time. Go to the lectures, its worth your time, and do the practice problems in the book and you will do well.

I took this professor for 2040 and again for 2041. His tests are always consistent.

Professor Hernandez is a very intelligent and well-rounded professor. You can tell he is passionate about what he teaches and is always willing to answer questions as well as clarify any confusion. His tests are based on the homework questions and are not that hard if you actually pay attention in class.

The people that complain about him should go back to high school, if you READ, go to class, and do the problems from the book, you should be fine! Yes, tests can be hard, because he wants you to think, but he is a great professor and even if he seems scary, go to his office hours and he will be very helpful!

Very good professor, he makes you learn the information rather than memorize the information and his style of teaching is very motivational and encouraging. You wont get an easy A but if you work for it the test won't cheat you out of your grade because they are more than fair.

Hernandez wants you to learn rather than to memorize. If you had any questions his office hours were mostly helpful. Biggest recommendation is to practice the problems from the end of the chapter in your textbook. If you are comfortable with those problems there is no reason you shouldn't get at least a B on your tests. You have to work for an A

Professor Hernandez is a very good teacher. His main point that he wants his students to learn in the semester is to actually learn the concepts and material rather than just memorize it. If you actually go to his lectures, do the review problems at the end of the chapter, and just put in some work then it's very easy to pass this class.

Hernandez is by far one of the best professors I've had at UCF. He knows exactly how to teach concepts in a way that helps you feel confident about the information without having to memorize it. If you do your part by reading before class and study hard it will definitely pay off in the test which are only 20 straight-forward type questions.

Loved taking this class. Professor Hernandez hates cell phones, so make sure yours is on silent and put away or he'll kick you out of class. Three tests, around 15 questions in total & Final Exam (cumulative). No homework graded but I'd suggest to at least look over and do some practice problems beforehand. Funny, jokes a lot in lecture.

Dr Hernandez wants you to THINK not memorize, having said that some of the test questions are harder (trickier) than others, he seems a bit moody and despondent sometimes (picking up test at the last minute? Good luck). Overall a good teacher, chemistry is just hard.

Hernandez is a pretty good teacher. Most of the things he teaches are pretty clear in my opinion. To get an A you need to do every problem at the ends of the chapters as most of the test questions are based on those and GO TO CLASS. Just like in life if you want to be successful in this class you just need to work hard.

I thought he was a great teacher, ALL OF THE NOTES AND LECTURES ARE ONLINE so you all you have to do is go to the lectures and pay attention, and the material WILL make sense. He is upfront about his grading and testing style. He gives 3 tests, & a final, and the final replaces your worst grade. As long as you study & try its impossible to fail.

I strongly believe he is a great teacher, he follows the syllabus and gives you all the powerpoints of the chapters and assignments to help you study before you even start class. All you have to do is pay attention in class, if he says something is important it is, make note of it. Great Professor and is always willing to help in office hours.

Don't text in his class you will get thrown out. Other than that Doctor Hernandez is a great professorm he knows what he is talking about and hw ould gladly explain you anything in his office hours. Do ythe problems he assigns as practice for the test, study HARD, and when ever he says something its important it is comming on the test so study it.

Doctor Hernandez is probably one of the best professor i ever had. The class will be hard if you do not study, but if you study and go to class like you supposed to you'll do fine. one thing about the class is that the grade is based on 4 exams and if your not good at taking exams don't take the class, but other than that this class was great.

DR. Hernandez is a great professor and takes the time to teach you if necessary and really cares for his students understanding. He is a lot nicer in person so go to his office. The class is tough but chemistry is a tough subject. Many of his questions come from the book so do them all. Theres only 4 tests. Hell try to trick you know your material.

He's hard and you will have to do the assigned problems, but he prepares you the best so if you want an easy chem grade go somewhere else. Kind of a jerk but he's good at what he does and people are too soft. Taking him again for 1b

Dr. Hernandez wants the students to understand the concepts of Chemistry. The tests in his class are pretty straight forward, all of the material is covered in his power points but reading the book gets you further in the class. Some of the questions on his exam come directly from the practice quizzes in the textbook! Final replaces lowest score!

Had him for Chem 1A, grades were composed of 3 tests and the final. If you go to class the information becomes much clearer and he goes over questions in class that are similar to the test. He isn't specific in what you need to know, but for Chem that pays off in the long haul. Need the textbook for studying purposes

Not much homework, puts notes online, and always helpful.

No homework, just study notes/book very well, attend lectures, and do practice problems to do well in class! Grade is composed solely of tests, for which he has a generous curve. Final exam score can replace lowes test score.

I took two classes with Dr. Hernandez, CHM 2040 and CHM 2041 and with hard work and determination I did very well in those classes. Dr. Hernandez is a challenging professor but is fair and you get the grade you worked for. He is funny and his classes are not boring. Read the book, go to class and you will be fine.

Professor Hernandez is a great professor, he is passionate about what he teaches and makes the class fun and interesting. i took 2040 and 2041 with him and i would take him again, he challenges you but doesn't test you on something he didn't teach or not in the book. He really cares about his students and try to make sure that they understand.

Very passionate professor. Ask for help, he'll give you help. He has humor, and he respects his students. Great guy. His tests though are very hard. Even if you study super hard, some questions will trip you up. A lot of questions are cumulative, some are very abstract. I feel like there are easier profs out there. I wish you all luck!

I absolutely loved his class. I have taken seven levels of chemistry classes, and he was my favorite professor of all. He truly loves what he does and wants his students to succeed. I always looked forward to his class. Also, he had an easy final and gave extra credit. He's a pretty neat guy.

GREAT PROFESSOR!!! I am so glad I took him for my Chem 1 B class. He was a great professor. Taught me a lot in the class. I really like his teaching style.

took Chem1B in summer B. Professor Hernandez did a great job explaining the material. The class is lecture heavy and you may have to read the textbook for better understanding. Study a lot of the practice problems and It'll be fine.

I didn't like the class because the only grades you get are the four tests. But, his powerpoints are very clear about what will be on the tests. Study his examples and book problems he assigns and you'll be golden. I suck at chem and did good. He said final would be cumulative but heavy on one chapter, ended up all being that chapter. Didn't lie

Professor Hernandez is a great professor. The class itself is difficult. The only grades are test grades, but he replaces your lowest score with what you score on the final, that was great. Its vital that you do as many practice problems in the book as you can, thats how to pass chem. You have to practice. Good professor though, nice and helpful.

4 midterm exams, 1 final. If you're a STEM major & are good at chem, take him bc the course layout will prep you for harder chem classes that you'll need (chem 2, organic, etc). If you're just trying to fulfill a GEP/you aren't good at chem/you're a bad test taker, don't take him b/c there are no "buffer grades" (quizzes, hw, iClicker, Aleks).

All his tests were information given on his powerpoints. All i studied were his powerpoints and ended with a B. Very fair with the tests, easy test questions, but they are 20 questions. Focus on powerpoints, he likes coneptial questions more than the actual math questions. Explains really well the powerpoints in class, so go to class. 75-89 is a B.
