How would you handle a coworker ( your trainer) who speaks to you in a very condescending tone?

She doesn't speak to ANYONE ELSE the way she speaks to me.

She'll route back items that I've made a mistake on ( through the computer) and wont say whats wrong with it. When I ask, i get told to figure it out. Like in a rude way. Anyone else asks " oh look right here, you forgot [blank]".

I haven't even been here for a month and I'm tired of putting up with her antics.

The manager seems rude herself. She's never asked how things/ training is going.
