Yeah but timeline is missing him going into the Nurse's office (as the nurse states he did)

And also when it was he had shot through the door into the second injured woman(shot her arm and leg)..

Also when did he visit the other class where he was banging and yelling "let me in let me in"
??
He would've shot through he wouldn't just yell.

Found that on one of the links from this thread- she's right it needs to be counted for on timeline:
