I did not expect a teacher of this caliber when I first walked into this class. Clear, intelligent, helpful, fair; all of which describe Professor Navarro. His exams by no mean were easy, but Organic Chemistry is simply difficult! He taught well enough to make it seem like a cake walk. Go to class put some effort and thank the heavens for Navvaro.

Just say his name on campus and you'll get a review on him, even from students who didn't have him. Orgo isn't a easy class that you can master on your own. You need to do your work but also have a good professor to guide you, which he is not. His slides are horrible, his lectures are fast, and his test are killers. Take him on your own will.

It's not hard to find out how many dropped his class. It was not that his exams were too bad, but how unreasonable he was. His first test average was a 33.5 and the second one was 44.5. He believed it was enough of a jump to not curve at all and fail anyone who got under a 70. Anyone in the 60's was to get a C- or C+ with high recitation.

Not the warmest professor I've ever had, but you learn a lot if you pay attention and take copious notes from the textbook. If you've studied, quizzes are a breeze; problem sets he posts are easier than the tests themselves. If you want to take this class, just be prepared to work. Also, he looks exactly like Fred Armisen.

For orgo 2, recitation quizzes are now equalized between sections so ignore anything about difficulty and pick a professor who will TEACH. Navarro was great at teaching recitation sessions.

Great Professor, he doesnt use slides, only teaches on the board, very logical style. He is very smart and funny. Exams are not easy but if you follow his lectures and work on his practice problems you should do well. I found very useful to attend to his office hours, he was very approachable and helpful. I wish I had him for orgo 2 as well !

He tries to teach. However, there are many cons to his method and quality of instruction. He speaks way too fast for a course that is so advanced and requires deep understanding of topics. He does not explain topics well. He did not give us the solution to the homework problems.

Prof Navarro was really great, he is a very smart and knows the material incredibly well. He is very also passionate about Orgo Chem. His teaching style is very logical. He was very approachable during office hours and his tests were quite fair. To do well you need to stay on top of the material since day 1. I will definitely miss him in organic 2.

He recently started posting youtube videos which were very helpful to watch after a lecture because they solidified my understanding of a theory or lesson. If you ask he makes online office hours before an exam, as well as an in-person one. You should go to class as he doesn't post slides, and he also answers your questions thoroughly.

Avoid this professor, despite him being the most readily available during regular semesters. You are much better off taking this course, somewhere else. He knows in orgo but cannot simplify it to communicate his message; his tests are awful. To give you an example, Fall/Spring average for test 1 was around 50s while summer semester was in 70s.

AWFUL. He goes so fast and there are no slides so easy to get lost. He doesn't prepare you. His exam review didnt come with answers so it wasn't helpful..Each exam is worth a lot. (30%,30%,40%) Not helpful if you are not doing well and rude.

Honestly the best organic chemistry professor, incredibly kind and empathetic towards students. He genuinely wants you to succeed. Take advantage of his office hours he is very accessible. It is a hard class you have to study from day one, and the material builds on itself. He explains concepts very well

Navarro is the best lecturer I have had at Brooklyn College, he is incredibly knowledgable and he really cares for his students. I attended to his office hours regularly and that made a big difference. The class is not easy and you will have to study hard but if you work on the problems he provides you should do well in his exams.

Came in deathly afraid of Orgo as someone who sucked at gen chem and barely survived pre-orgo, but ended with an A-! His exams are hard, but he does a good job preparing you (coming from someone who rarely attended lectures). GO TO OFFICE HRS.Taught me how to thoroughly analyze and understand Ochem.

Overall challenging class. Expect to devote 4-5 hours after each lecture to solidify the material. This course was TOUGH, and extremely time consuming. The exams were on the "difficult" side. Study HARD, always remember why you are taking this course, and you will DESTROY this class. Think clearly on the exams, because they are made to TRICK you.

Lectures were very helpful, he knows the material really well and he is really a great lecturer, very logical, organized and clear.

He is a great professor for understanding ochem. All of his lectures make everything piece together really nicely so I would highly suggest attending to get a grasp on the material. This class is difficult solely because you REALLY have to understand it and practice. (P.S. his preorgo class is actually really helpful for this class)

Would provide practice for Ochem but little to no solutions. I brought it up he suggested that I should've come to his office hours to get them corrected, which was quite inconsiderate since I had other classes during that time. Also lectures were a little pointless since I taught myself everything anyway. Office hours did help though.

Very smart guy, no slides in class, just him teaching the material, reactions etc on the board, which I appreciated a lot. You do have to pay close attention though.

Firstly, during the lecture he goes extremely fast. If you ask questions, he makes you feel dumb. In addition his favorite word to use when explaining is “obviously”. Secondly, if you go to office hours, he will “lecture” you about ur study habits instead of helping you understand a question. Thirdly, he provides practice but with no answer key.

He does not tolerate disrespect so beware. But ultimately he wants you to do your best, ask questions, and encourages you to work hard and come to office hours. He can be kind but he also does not play, take this class and him seriously and you will pass. Ask questions, he doesn't use powerpoint he just explains examples he writes on the board.

First professor I've had who teaches out of his brain, no ppt slides, no papers, nothing, insane how he can do that, especially on this subject. Lectures are very organized, his teaches you to reason the topic never to memorize it. He is brilliant and also quite serious about discipline in class. Very helpful and kind in office hours.

Doesn't know how to teach. The class is already hard but he makes it ten times harder than it needs to be. You have to read the textbook and teach yourself everything. He expects you to know everything from the get go. If your go to his office hours with a question he will be rude to you. The exams were confusing and the assignments made no sense.

If you are deeply interested in and love Ochem this is the professor for you. He's knowledgable, will go over everything as much as you need and keeps his office hours going if ppl are there. BUT if you don't love chem, he aint it for you. He's a very tough grader and expects you to KNOW this subject inside and out. Wait a semester and take Mohd.
