Chem 9 Taken for Credit:N/A Attendance: Not Mandatory Textbook Use: Barely cracked it open Rater Interest: It's my life Grade Received: A+

Ron was a real cool teacher. He was laid back and didn't make learning chemistry feel like a chore. Easy class if you actually study your notes. Tests are always straight from your notes! He goes over tests prior to the exam so if you don't pass, its because you didn't study. Rons really funny too!

BOOK IS NOT FOLLOWED LAB BOOK DOES NOT COINCIDE, JUMP ALL OVER BOOK, BETTER FIGURE IT OUT YOUR SELF OR TRY TO FOLLOW THE FAST LECTURE NOT WELL ORGANIZED. OLD NOTES, CHEM TUTORS HAVE TROUBLE HELPING. SKIP BOOK ALL OVER AND LAB MANUAL DOES NOT COINCIDE, FIQUIRE IT OUT FOR YOUR SELF. IF U CAN SPEED NOT WRITE AND LISTEN!!

chem 9 Taken for Credit:N/A Attendance: N/A Textbook Use: You need it sometimes Rater Interest: Low Grade Received: N/A

Ron really knows his stuff, biochem especially. Does a good job relating the material to nutrition and exercise(sports). Keep things light and moves fast but reviews and reviews important material before the test. Don't miss his test reviews and go to class and you'll do fine. Not too much homework given and will give extra credit.

Ron is very easy to talk to,but you really need to stay after class and clarify questions or else he wont go over them. he expects you to be knowledgeable on chem. hes old school and only does notes on the board. it takes a while to get used to his teaching style, but his test are taken directly from the notes. put the time in and youll be fine.

Labs are easy and some are fun. Lectures can be a little difficult to follow as he can jump around a bit but he always stops and answers questions. Little homework and if you go to class you will know exactly what is on the tests weeks in advance.

a couple tests and he tells you specifics to study the week before. labs are fun, hardly any homework, test can be difficult but if you study youll be fine. Hes kind of scattered and goes quick during lecture but he'l explain it slower if you ask him. hes really funny and down to earth.labs were fun&always flew by. we always got out early

CHEMCHEM Taken for Credit:N/A Attendance: N/A Textbook Use: Essential to passing Rater Interest: Really into it Grade Received: N/A

Decent teacher. I have prior chemistry background so that helped a lot. Lectures incredibly fast, and dont be surprised if you leave class almost 30 mins early all the time. Exams were hard, found it easier to study the book although his exams are usually relevant to his lectures. Gives extra credit and homework. Must keep up on material. Grade B

Chem is not easy, but Choppi is a great teacher. Very helpful, fun to be in lab with. Be sure to study and ask questions. His writing on the board can get messy and confusing, but he's not hard to follow. I'd definitely take him again.

CHEM9 Taken for Credit:N/A Attendance: N/A Textbook Use: It's a must have Rater Interest: Really into it Grade Received: N/A

VERY knowledgeable on subject matter. Lectures VERY fast and covers ALOT of material at once. Helpful after class, just gotta ask him. This is a true 5 credit course with lab. I don't recommend CHEM 9 if it's your first Chem course. Take CHEM 10 first. If you take him, make sure you read the text before lecture, otherwise you'll be totally lost.

Choppi is an awsome teacher. He is a little scattered and unorganized but he is very approachable and really wants you to succeed. His wa of teaching made me remember and understand chem 12. He gives study guides. Tests are based on notes. Reading the book made it a lot easier when taking thhe test. Do all HW. Do not miss any class notes.

Does talk fast & writes a bit sloppy but you get used to it. Three exams, chapter homework, quizzes are for extra credit points, lab was a little tricky, but REALLY kick back. Choppi is laid back & helpful. I do agree with comment below that he is hot... but in an old guy kind of way.

talk fast & may write a bit sloppy, but once the class progresses, you realize he's pretty laid back & funny. Tests are what he lectures on (use book for reference). 3 tests, quizzes were extra credit, lab was tricky but kick back. I agree with the comment below with Choppi being hot for an older guy.

Mr. Choppi is a nice person. But I felt that during lecture, he was not really helpful. It always appeared that he was in a hurry to leave. He talks fast when teaching. You are kind of on your own when taking his class.

I love Mr. Choppi. He really makes you sweat through this class. In the end he is really fair and for an older man I think he is pretty hot too. You should go to class because if you miss you can really fall behind. He does seem to be a bit impatiant but will help you if you ask. Go to the learning center for help with the labs. Good Luck!!

I am going to tell you this teacher sucks.He is sloppy, goes too fast and doesn't explain things well. If you ask questions, he acts like he's mad. Like duh, you dont understand? He is always in a hurry to leave, YES FOR SPORTS. So it's your problem to figure out whats going to be on the test. I would not reccomend him at all.

P. Choppi takes an very difficult subject and makes it entertaining. He does talk fast and erases things a little too quickly, but is more then happy to answer your questions. Your textbook will be your best friend - be sure to use it and the tutoring center. Work your butt off and you will do fine - no free rides in this class!
