Is it normal i can not find classes at night?

Uhm, well, to be more thorough...

It's usually community colleges that offer the night classes because they cater better to working adults. You can easily take classes at a community college and transfer to University and it will save you A LOT of money so look up local community colleges in the area for night classes.

Now, when I say funding, I don't necessarily mean expense. In fact, just the opposite. For state funded schools that run both on money from the government AND from private funding (i.e. tuition costs), the better funded that they are, usually, the less expensive that they are relative to Private colleges (like Harvard and Yale), a state school would be like San Diego STATE University, or Asheville-Buncombe COMMUNITY College.

Generally, any college with the words "State" or "Community" in it are going to be publicly funded schools and generally community colleges cater to working adults. However, if a community college doesn't receive much funding, they will have less classes to offer and night classes and summer courses are usually the first to go when funding is cut.

So don't go to a more expensive school just yet, try community colleges and state schools first. Private schools typically cater to a better moneyed crowd and if you grew up in a household that has money and therefore CAN pay to go to this school, it's unlikely you'll have to work through college.
