Best way to move forward in learning spanish?

I currently attend a school in Mexico city to learn Spanish, I'm in básico 1. The school is expensive though, about an additional $13000 pesos/month. I want to learn Spanish so that I can go to a local university. The classes are 3 hours a day and 5 days a week.

Right now I have no money to go out and do stuff, so I was wondering if it would be a good idea to not enroll in the classes next month and taking one 8 hr class a week in addition to personal study... Would that be a better idea? Because now I am unable to actually go out and speak Spanish because I am spending so much on classes.
