ER modeling exam interview with BB next Tuesday (3 hours), looking for some resource guidance

Hello internet friends! Long time lurker, recently made an account as I graciously got a second round at a BB for a modeling exam with a maximum duration of 3 hours. For a lil bit of background, I am a fresh grad interviewing for an associate position with an "intermediate" finance background (ik the terms and concepts behind a financial model but have very little experience building them if at all).

I did enough due diligence to guess the potential things I will be asked to do (updating a model based of a PR and writing a note, potentially creating a 3 statement, etc.) but wanted to ask if anyone had any resources to preview or know some good public examples. Given that it is 3 hours, I was also wondering what the "quality" should be (ik this is a case by case but if you were an interviewer, what would be passing for you?), given that some public examples of notes are really intense and fleshed out.

Thanks in advance and please let me know if there is anything else I should have added to the forum!
