My favorite teacher of all time! Mr. Clark was an engaging, educated, helpful teacher.
Mr. Clark is the SMARTEST chem teacher Northern has. We all love the pringle man!!! (only his tests are hard) but I still love him!
what more could you want than a teacher that loves blowing things up more than his students do? his class is difficult but worth it.
MISTAR CLARK NUMBER ONE BEST HAPPY FUN TEACHER CHEMISTRY. ALLA TIME BEST! seriously, this guy rules. take his class(es).
I don't really like Mr. Clark. He's really boring and he over-exaggerates and stretches out everything he has to say. Very nice guy tho.
I went from a 44% in chem to a 96% in 3 months. best teacher in school
Mr. Clark's jokes are the best and he's a great teacher!!
its chemistry so its not easy but he's an awesome teacher!
