Do I need "the" before "class"? I seem to recall (from my school years a long, long time ago) that with words like "school" or "home" or "church", no article is needed. Is "class" one of those words?
She is in class (at her school) right now.
She is in class = she is currently taking part in a lesson.
She is in the classroom = simply a statement of her location.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
