Help with my Spanish composition, por favor!?

When you define what "comercio" is, do you mean to write it in Spanish? If that is that is the case then I think it would sound better if you wrote "especializaci�n en finanzas". The word "financi�n" is spelled incorrectly, it should be "finanzas". If you wrote "los lunes y jueves" you should write "los mi�rcoles" as well. In the last sentence when you say that you eat with your friends at the Uni Bar, you cannot say "con nuestros amigos de otros" it would be much better if you say " con otros amigos de nosotros". Other than that it's great spanish! Keep up the good work! :)
