Hello. I'll really appreciate it if you help me with a few questions.

1)Is the article used in the context "I am late for the (?) class"?
2) What is a natural way to ask a question the answer to which will be "twenty minutes, I am 20 minutes late for work." Maybe, "How much time are you late?" (it sounds strange to me.)
3) Do you think the following questions are OK?
a)What are you agry with your sister about (over)?
b) About (over) what are you angry with your sister?
Thank you for your answers a lot.

Question 1 is fine, but could be "my (blank) class."
Question 2: Yes, your question does sound awkward. It might be, "How late for work are you?"
Question 3: About is better than over.
