Here is an idea for the OP that saves time and money:
Don't go to college, but take evening classes at your community college. (like stats, math, psychology) Even if just for a year, you will save a shit load money and you can even trade during the day.
Advantages:
1. Obviously cheaper than full time college.
2. You can cherry pick your classes and take only what you think will be useful later on, instead of having a major with a bunch of BS classes.
3. You can start trading (and losing money) right away, while you are doing this.
Also, there are some online trading college classes if I recall, they are just hard to find.
So if after 1 year you still think you want to be a trader, you can keep doing this until you think your education is over and you are actually profitable. If/when you get fed up with trading, you will still have a few most likely transferable classes and you can go fulltime student...
In short, you get best of both world....
