Explains everything to the fullest. Awesome professor!

Great professor, makes learning chemistry fun. I actually look forward to going to class even the though the class is not easy.

HIS NOTES ARE VERY HELPFUL & COINCIDES W/ HIS TEACHING METHOD. THIS SEM WE ASKED FOR A PRACTICE EXAM ONLINE AND HE SET ONE UP! THE PRACTICE EXAM MIRRORS THE TEST. DO ALL THE HOMEWORKS & LAB TO HELP YOUR GRADE TOO. THIS IS AN EASY A.

Mr. Lopez is helpful and avaliable to help when you need it. He is prompt to answer phone calls and he is helpful in homework and lab work. By far he is the hottest professor at SAC.

Mr. Lopez is great. He presents the material well and is fair. He is always willing to help and is very easy on the eyes. Best prof at SAC!

I did not want to take chemistry before i went in, I was really expecting the worst, but Mr. Lopez made the class so much fun and so interesting. I really loved him as a teacher. He also curves most of the test so that really helps. The homework is so helpful and really helps you to understand material, and the same for his notes. Great Prof!!

A very nice guy who seems to really like what he does. Lecture notes are good, lecture is fast-paced and interesting (coming from a Bio major who hates chemistry). Very easy on the eyes :P

Definately not a class for slackers. He goes deeper than the book and gets further than most of the other professors. Drops one test grade, but TONS of homework. Final was really tough and seemed like it was written by someone else. Always available for help, but many students felt intimidated by the way he answers your question w/ another question

This professor is very helpful. He gives you all the information you need. If you attend class, pay attention and do the homework (tons of it) yourself, you should understand the material. Most did not like him. His sense of homur is different. His final seemed easier than his other exams. Without a doubt you have to study and earn your grade.

Summer I class is not recommended if chemistry is not one of your strong subjects. You have to work to earn your grade. This class is not for slackers. I enjoyed his class. I would take him again.

I liked Mr. Lopez. He gave homework which was hard, but there was enough time to get help, and in the end it was better as a review and helpful with my final grade. There were times when I didn't want to ask questions because he had previously made me feel stupid, but I might have waited till the last minute too much. He is also quite handsome!

Good teacher! must read text! alot of test material was not gone over in class! easily available!

Great guy!! Our class had lots of fun. His door is ALWAYS open and will help you figure out the key seq. on your calculator, if you are like me and are to cheep to buy an easyer one. Chapter Readings are suggested and I would have done better had I read them. If I had studied more I would have got an A. I deserve my "B". WOULD TAKE HIS CLASS AGAIN!

Chemistry defintely not my favorite, but really enjoyed this class. Prof can seem a bit aloof, but always willing to help me when I asked. Others in the class didn't like. I'd recommend him. Do the homework, don't be afraid to ask questions and do well on the tests (there's a weighted average). I made a B, think I could have done better.

Mr. Lopez is the nicest teacher ever. He was always available during office hours for help, and would explain everything until you got it. The homework was hard and no fun but helps. You have to do lots of reading and studying to pass. I would def take him again!

he's awesome, helpful and very clear and funny, i always tried to pass chemistry but never could. but he's so helpful and WILL answer emails and whatever you need. i love chemistry now and so excited about medicine. so take him if you want to LEARN chem, not just pass!!!

Mr. Lopez is a lively and engaging teacher. He answers questions in class and is more than happy to work problems on the board to clarify any issues. He makes his notes available online, so reviewing them and completing the homework should set you up to do well. He's taught me to love chemistry, something I never thought I would.

CANT MISS CLASS>If you end up with a passing grade, you will KNOW thoroughly chemistry to the point where you can tutor it. The only problem is that he Weighs his tests 70% of the entire grade.LABS 10% HW TOTAL!=20% its BS!It leaves VERY little error for mistakes on the tests. if you miss one written problem, it can drop your test one letter grade!

I was so scared to take this class, but instantly fell in love with chemistry! The class is difficult, and you will need to study, but Prof Lopez will help you any time you have questions. Do all of the homework and make sure you understand it and you will get at least a B. Gives progress reports so you know where you are. Loved the class!

Probably the most difficult class that I've taken in all of my college career! Wow! I am an A student but took this class in the Spring and my grade dropped to a B because of the difficult tests. He made half multiple choice and the other half written out. If you miss one ques, it could drop you a letter grade. Watch out for ch. 9 & 10!!!

This class is not easy- but it is because chemistry is not easy. I took this class during the last spring semester (09)and I got an A. if you want to make an A doing homework and reading his slides is not enough- YOU MUST READ THE CHAPTERS, and that's what he said at the beginning of the semester. Besides that he's very helpful, clear and funny.

Besides that he?s very helpful, clear and funny.

He has a sense of humor and isnt a stiff unless ur afraid 2 ask. I recommend him highly but ask questions and expect sarcasm. It could b worse.. generally classs does move quickly but everything he teaches can b learned in the book and his lecture notes (slides). B mindful about the tests they incorporate everything over the semester.. SIG FIGS! :p

Chemistry was a hard class.I recommend him highly but ask questions and expect sarcasm. My biggest problem and he will not change it - is that on the day of an exam, he will do lecture first on the on-coming chapters and then the exam. READ the BOOK.... and do many many practice questions and you will get an A or B at least.

best teacher ever had!!funny,hot guy!!

I have I do not do well easily in classes but Lopez is a great professor. He gives HW assignments that are tough and require effort, but after doing them you know the material. Labs are great because he doesn't let you leave with out a grade of 100. Lab quizzes also easy 100. With HW, Lab, and Lab Quizzes, lower test averages dont hurt as much.

Took him for Summer I Chem 1405. Teacher is extremly helpful!! Always answers any quesions you have during class. He even asks students during class if they want examples done on the board. Labs were a bit easy. Just show up to every lab and you get a 100%. I would definity recomend this teacher for someone that is needing a Chemistry class.

Mr. Lopez is a great teacher. He is super helpful and very funny. I took him for Summer 1 and I got an A even though the class is hard he made it very easy to understand. He even gives you his phone number if you need help. I would definetly recommend him to anyone needing Chemistry

Prof. Lopez is an awesome instructor. He makes chemistry fun and easy and the people making comments about having to be female to make an A are obviously students who did not want to put in the effort required to make an A. Do the homework and assignments in the book and attend every class and you too can make an A.

Mr. Lopez is a really great teacher! Although the class itself is tough, he provides plenty of help via text or phone. He makes the class fun and interesting... by far my favorite class. Definitely recommended!

Pay attention, memorize what he tells you to(metric system & such,do the HW over & over you will get an A. I got a B, mainly because I was taking Anatomy II(A) & Nutrition(A)at the same time & a mom of 2 young boys & have to take care of 2 sick family members I only had time to go over it once before the test with more time I could of gotten an A.

Mr. Lopez is very good about always being there to answer questions but he always answers your question with a question! Honestly the class isn't very hard, but if you take him for maymester it is very fast paced! :/ Take him during a regular semester and you should do fine! He drops lowest test grade and lab grade and HW grade!

He is a wonderful teacher! I took him for maymester and recieved an A. As long as you do the homework you WILL pass the class. He gives wonderful notes as well. Very helpful and ALWAYS availible to answer questions even outside the classroom! I would definately recomend him and take his course again!!!!

He is a wonderful teacher. I took his class for maymester, extremely fast paced. As long as you do the homework you WILL pass the class. He gives wonderful notes as well. Very helpful and ALWAYS availible to answer questions even outside the classroom!

Just be sure to look over your material before hand. He expects you to be prepared! This is a good instructor.

He is good.

Great professor but he won't just hand you a grade. Imagine starting from zero and working YOURSELF up to the number you get...Do the homework over and over and practice ALL quizzes before EACH test! He will help you get into the habits that you will need for Nursing School. My favorite class.

I am in his class right now and at first I hated this class but now I don't mind it. He is a good teacher and puts things into simple terms and not chemistry terms. Chem isn't an easy class and he gives his students good habits to use in nursing school.

The class is very hard but if you study a lot you will pass. Always print out lecture notes ahead of time. Do the home works he wants you print out. He drops one lab grade, one quiz grade and one test grade. You have a quiz each week so make sure you study. He is helpful if you want the help. The labs are easy the tests are tricky. He is sarcastic

He is a very good teacher! He puts everything in simple terms and gives you the tools you need to make a good grade. Every lab you make a 100 and he gives hw to practice for the tests. Most of the test questions are straight off the hw. He is very sarcastic but very funny. I would definitely take him again!

He's good. I'm currently in his class and actually look forward to going to class. It's hard but practice helps a lot! He gives you everything you need to study it's up to you to actually do it

He locks the door the minute class starts which is annoying. Attendance alone dropped my grade a whole letter grade. The class itself is fairly good, he posts his lecture online & hw on schedule. Makes it pretty easy to understand. He talks to you like a kid though, other than that his class is fairly easy to pass given you listen and do the hw

He definitely is a hard ass when it comes to attendance but it's something that everyone needs to learn anyway. He's funny and a little out there but it's nice! Also, he goes through his lectures pretty quickly but if you need him to explain stuff more before moving on, he will. You just have to stop him and ask. I would take him again for sure.

I'm in his class right now, he is big on attendance. He locks the door as soon as class starts, which can be a pain in the ass but I think it is good. It teaches you to be on time. He is hilarious. He does respond very quickly to emails.

Don't let the other reviews keep you away from taking this professor! 3 exams, 1 comprehensive final and he drops the lowest test grade as well as lab, which he doesn't give exams for! He explains topics really well!The HW does not count for a grade but DO IT, it makes such a difference when you've had practice. Also, quizzes for extra credit!

Took Lopez during the spring of 2016, beware exams are all MC and small math portion. No partial credit is offered, its all or nothing. Tests are curved though... All labs are a 100 if you do as your told! He's very nice and funny in class. If you get 5 or more questions right on quizzes, he will add 1 point to your exam grade. (all quizzes).

Overall not a terrible class. Quizzes are extra credit, tests are all MC with a small math section. Questions on the test are all or nothing, no partial credit. Labs are really easy, always gives 100s as long as you show up. Some of the labs you can even complete before class time. Puts hw and labs on canvas so you dont need to buy anything

Lectures are a bit fast paced, but all the PowerPoints are very thorough. Homework is not graded but definitely helps with exams. It's not easy but it's definitely possible. Absolutely recommend taking Proffesor Lopez.

Took Professor Lopez Spring 2018 for General Chem 1 and his class was a breeze. If you do the hw and actually understand it, youll be fine on the test. He drops your lowest test grade and gives extra credit. I wish he taught Chem 2 :(
