I am doing research for a paper and I can't find anything since the internet is so crowded...

The Internet is "crowded"?

What kind of schools? How late in the day?

What exactly is your research for? Subject? Title of the paper?

I am not going to look for you, sorry. Maybe someone will, but you are too vague about the whole topic. You don't say whether public or private, grammar, grade, middle, or high, college/university. You don't say what you consider 'later.' Too vague!

I think the OP means that the internet café is overcrowded (maybe)

OP we really do need more information before we can help you.
