Doesn't even teach our class just tells us to answer ridiculously hard worksheets. He also doesn't tell us the homework we have, he says its on the so called "planning guide" that he never puts up.

He made un of me a lot. Also, I learned nothing. I did well in the class, but the only thing you really need to do is hand in your assignments. In addition, if he's ever not in school, there's probably a sale at Boscov's.

Class is pretty easy and we moved through the book very slowly. He dfinitely knows his stuff, and is willing to go in early to help you.

BEST CLASS I EVER TOOK IN HIGH SCHOOL. ONLY TEACHER TO OUTRIGHT MAKE FUN OF KIDS IN CLASS AND THEN ACCEPT CRITICISM IN RETURN. NEXT YEAR IS GOING TO BE TOUGH WITHOUT THIS CLASS: DUE DATES HAVE TO BE TAKEN INTO ACCOUNT, NO MAKING FUN OF CERTAIN STUDENTS, AND NO DR. J. IT'S GONNA BE TOUGH

Dr. Janasik doesn't teach in the conventional way. He mostly hands out packets and makes you do a lot of busy work, but it works and you will truly learn Chemistry if you do the work he assigns. Plus, he's a really fun teacher.

It's not hard to get a good grade in his classes if you work hard. He's honestly not the best teacher but you do learn Chem one way or another.Does not prepare you well for AP exam, but he's not bad.

possibly one of the worst teachers i've ever had. and i like chemistry and pulled As in chem. You won't learn anything even on the days he actually decides to teach instead of just handing out packets

I truly believe that this man was one of the best teachers I have ever had. He helps student understand the material but, more importantly he makes his students better people.

I liked him...didn't think class was impossible; useful info for college classes; went to europe with him on a class summer trip with a bunch of people and had a blast.

I actually really like him and think that people who don't probably aren't doing well because it's chemistry. He always took time out to help me and I learned a ton that helped me in college pre-med

I'm not giving him a good rating, even though I don't mind him all the time. He can really be a pain because he just makes stuff up and puts the most random stuff on his tests.

Dr. Janasik is an intelligent person who knows how to teach and knows how to get students interested. Sure he is strict and it's a difficult class but it's Chem I LOVE THIS CLASS!

I can sum up the Janasik expierience in one word: chemistry??? Maybe if he spent less time trying to be funny and more time teaching, we'd be able to learn.

If you're known to be smart and want an easy, good grade, he will give you one, since he grades on reputation-don't expect to learn anything
