When the bus came, the children rushed up the bus.
Is 'rushed up' correctly used in the above sentence? I wonder whether it is because it is not correct to say 'got up the bus'.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.

You need a 'to' after 'rushed up' to make this sentence work. Or you could drop 'up' and put 'onto' in its place.
You are right.
