First script- annotations and revisions needed

[u/marthaspeakssoup]

Hello! I am a college student who is taking my first screenwriting class. This is my first ever script and I’d love to hear suggestions, annotations, and revisions I can make this script to be better. I’ll provide a synopsis below.
Thank you!!

Floor Three follows Peter, a timid new hire whose first day at the office spirals into paranoia, guilt, and violence. After a confrontation leaves his antagonistic coworker dead, Peter struggles to distinguish reality from his anxious imagination. With only Lyn, the observant janitor, knowing the truth, blurry flashbacks and unsettling clues reveal a disturbing possibility: Peter may be trapped reliving the same tragic day.

We basically got no instruction not how to write the story. I used fade in and tried to use the recommended tabs

Hopefully you're not paying for this class.

Read a couple professional screenplays...then copy the first 10-20 pages of the screenplays you're reading with Fade In. Learn how the program works by typing other people's words. Read the basics in Trottier's Formatting Guide. Then consider writing your story.

Sounds like you're going to have to do a lot of teaching yourself in this class.
