Home inspection Monday

I have read that people have had multiple homestudies. They didn't say anything about another one???? But he said it will be 4 hours plus inspection. Did everyone's add up to that long and they were just separated, or are there multiple 4 hour homestudies ad they just have't said anything about another one? Freaking out now! It is at 1, prayers please!ETA: the letter N. It seems my letter N is going out and I need a new keyboard! :)
