"I'm great" sounds good if it's sarcastic and if you add "doing" --- "I'm doing great"... or just saying "great" would sound good. But I think you're right that just saying "I'm great" sounds a bit like you're saying "I'm a great person."

It depends on the situation. Most of the time it would be "get out of school," "get off school," or "school's out."

The difference between college and university really depends on where you are. In the U.S. we use the terms to mean the same thing, but I used to live in Australia and there they are very different because private high schools could be called colleges. A lot of the time a college refers to an individual school within a university, like the "college of business" or "college of science." A lot of the time it's referring to technical schools or community colleges.... it really just depends on the place.

All of them are correct, but we'd really only ever say "none of them like her." You could also say "not all of them like her," but it has a different meaning. "None of them" implies that not a single one likes her--- all of them don't like her. "Not all of them like her" is saying that the statement "all of them like her" is NOT true, but most of them could still like her. It just means that at least one or two don't.

The correct one is "between a desk and a table." A desk is used for studying or work and usually has shelves or drawers of some kind, while a table is just usually flat.
