He literally doesn't teach... he just sits behind his desk and makes us watch videos, take notes and quizzes all on our own without teaching us ANYTHING. His exams are literally impossible because we do bookwork, don't go over it, take a test, and then here him moan about why we all failed. I came to Benet to LEARN and be prepared for what the future holds for me... after taking geography w/ him I can truly say that I haven't learned a single thing in his class.

Worst teacher I ever had... Oh wait, he's not a teacher, he doesn't teach. Every student in all 4 of his classes will verify that he has never taught a lesson in his life. Instead, he just makes us watch videos and verbally abuses students daily. Oh yeah, and then there are the maps that "hardly anyone gets a 100 on" according to him. I got a point off for putting check marks in the direction box. He also makes up vocab for tests (one time all of the words were Arabic).TRANSFER OUT NOW

Worst teacher at Benet. "Teacher" is used loosely, considering Leffler has never given a lecture in our class and we have around 20 days left of school. All we do is watch videos and take notes on the textbook at home, and then take extremely hard tests based on material we 100 % teach ourselves. No exaggeration. Only thing the guy's got going for him is the zotts he gives out, which only half make up for his awful personality and 0 knowledge. Do not sign up for any class in which he "teaches".

His class is more challenging than my other classes, but still not that hard. He gives quite a lot of homework; it is indeed overwhelming at times. However, the worst thing is that he rarely teaches. Almost all days of the year, we have either been watching videos or working on assignments during class. He has only actually presented information to us on a handful of days.

Mr. Leffler is a nice guy but I don't think he should be a teacher. He assigns too much busy work to his students and he doesn't really teach. We watch cool videos in class but my class has not gotten a proper lecture from him since the beginning of school. Mr. Leffler has an assignment called maps that you do for every chapter. They take about a total of five hours to do and they are just busy work. You color them and fill in useless cities. I would prefer to have my old history teacher.

Boring, I can handle. Hard tests, I can deal with. Busy work, I can accept. Study hall to focus on all these things in place of the AP class I signed up for? That's pretty much where the line is drawn.

Mr. Leffler goes down in my academic history as the worst teacher I had ever had. He takes out personal frustrations on his students....while never really teaching anything. I'm VERY surprised that such an exceptional school would retain this man for 25 years. He's extremely lazy and often inappropriate in how he addresses students. I would avoid Benet altogether if I knew my child would have to be taught by this man.

I don't know why everyone complains about him. His class is very bizarre and his methods are a little obscure, but he teaches you what you need to know, regardless of the class. I think people just think he's weird and he does things a little differently than other teachers, so they immediately label him as "bad"...He does tend to hold grudges, so just be nice. Respect him, he'll respect you, easy A

Don't expect lectures in class, because all of the learning will have to be done on your own, basically. Do your work and try to participate a little bit, but in the end his grades are erroneous. Don't be afraid of him, although he tries to be intimidating. He can be very nice. He just expects efficiency and work out of his students.

Do the work, and stay on his good side, or youre screwed. He doesn't teach, so just be nice to him because he grades people on how you act.

He has a unique teaching style where basically he doesn't teach and everything is independent work. But his grading system is very fair and usually he changes your grade to your advantage! One of my favorite teachers albeit a bit odd.

Had him as a teacher 20 years ago. His first or second year teaching. He was abitter man back then. Leffler may have personal demons. I hope he eventually decides to seek counseling.

He was ok. I learned how to color. There was a lot of random stuff we did in class that had nothing whatsoever to do with geography. He also wasn't very nice.

Mr. Leffler has an "abrasive" personality. His bitterness is understandable if you listen to the rumors... He tends to be grumpy but his sarcastic humor is hysterical. I'm pretty sure I would laugh at anything he says. He knows what he's talking about and if he is in a good mood he can be really nice. Both in theatre as a director and in history as a teacher he has high expectations, and if you meet the expectations you'll do fine and you'll be better off for it.

Mr. Leffler is probably one of the only reasons why I stayed sane in Modern World. He is a funny teacher and if you pay attention in class and take good notes you will do fine and become one of his favorite students!

You learn but are not taught. If you want all the benefits of the class, just go buy a college text book and read it, because thats about all there is to this course, plus busy work. He is a lazy, burnt out history "teacher"
