I had a test last week and I had following mistakes.

Set great store by displaying humility, respect and formality.
Teacher: set great store by something (=noun)
They steer clear of showing disagreement directly.
Teacher: steer clear of sby/sth. eg: try to steer clear of trouble (=noun)

Our collegues are more common with us and dont stand out in bold relief against us like the Austrians do.
Teacherīs commentary: I dont know if this idiom exists.

Would you be so kind and check these mistakes. I strongly question my teacher. I am employed in getting familiar with http://view.byu.edu/. But it seems to be pretty complicated.
