He's just not a very good teacher. He gives examples, then sits down. It's not very helpful. He also plays favorites a lot. Hurtful to those of us who arent his favorite. I used to love math, now i really dont like it.
Very nice and funny but an awful teacher. He usually talks to the board but is willing to help you when you need it.
He doesn't really incite any emotion an anyone, he's just kinda.... there. Definetely not a bad math teacher, I felt I had an okay grasp on calculus by the end of the year.
He's so... blob ish XD really, he doesn't care about ANYTHING.... no facial expressions, nothing! XD but, he is an ok teacher, I think. just... eh. but class is easy :D
Hes ok, i wish he would S-L-O-W down when talking. and he isnt very fun. complains about getting off task, but if his class wasnt boring we wouldnt get off task.DUH!
fine math teacher. really gets us to understand. just a genuinely cool guy.
He makes the hardest math the easiest. If you want to take Calc, get him for sure. If you want to do well in AP test. Study for yourself.
Took very difficult course taught by Yandl, but he does an awesome job teaching it. Makes things very clear!!
A fun awesome teacher. He teaaches a difficult subject, but, he has excellent teaching habbits. You can tell he is an experienced and effective teacher.
I learned more from Mr. Yandl than any other teacher in my life.
good teacher for a tough course...even though he screwed my 4.0gpa
