I believe the answer is:

asses

I'm a little stuck... Click here to teach me more about this clue!

'it's foolish of them' is the definition.
I can't judge whether this definition defines the answer.

'cut classes' is the wordplay.
'ASSES' is hidden within the letters.
However, I am not sure how this is indicated.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for asses that I've seen before include "Pompous fools" , "Idiots" , "Hardy and sure-footed animals" , "Stupid people; Roman coins" , "Small, sure-footed animals" .)
