The nicest and most caring man I have ever met. 10/10
Mr. Acosta is the Best Man I have ever met in my Life. I am honored to have ever seen him. This man taught me fluent chinese and oaught me, even better, how to be a man. Mr. Acosta, AKA "Ke Lao Shi" is what people in my homeland call "A God in a Man's Body." If I ever meet another man who speaks 17 languages and spills a bigger place in my heart, I'll let you know.
Awesome guy, Regis is blessed to have him teaching here
even though chinese was hard acosta made it one of the most fun classes i've had. great teacher
He's super great. One of the best, kindest, gentelest, most amazing teachers in the school! Everyone loves him and he loves and respects everyone.
Awesome dude that knows almost every language know to man!
the definition of linguist. very concerned about his students. great teacher.
Excellent teacher, master of languages, humorous, very friendly. Has a great deal of knowledge outside of his field of expertise, as well.
This guy knows Chinese better than someone born and raised in China. He is not only a great and extremely fair teacher, but also an extremely kindhearted man, He is amazing.
Mr. Acosta is the most helpful, funny, and all around nice teacher I have ever had. Aside from being a genius with languages, he really cares about his students and their understanding of the material.
Mr. Acosta is awesome. He speaks pretty much every language ever...
Mr. Acosta is in all honestly one of the most birlliant men I've had the pleasure of meeting. He is extremely kind and always willing to help his students. Simply put, he's the man
Didn't have him as a teacher, but as an advisor, Mr. Acosta was the best guy EVER. Brought us doughnuts all the time, was as nice as could be. ACOSTA'S THE MAN!!
Mr. Acosta is probably the best teacher at RHS. He's most certainly the only teacher who could put up with my Chinese class.
Mr. Acosta is the greatest teacher I have ever had. He is the only person in the world I know that could have EVER taught me chinese.
I truly cannot say enough good things about this man. I've been in his French class for two years now, and he is by far the best teacher I've ever had.
Mr. Acosta is definitely one of the most talented teachers I've ever met. Only he can tell you you're special in Spanish , French, English and Norwegian...
