When studying English in Denver, it’s easy to get into a routine of classes, homework, sleep, repeat… so don’t forget to experience the new culture in which you’re immersed! The most enriching experiences you’ll have abroad are those made while doing things you wouldn’t or couldn’t do at home. Also, the fastest way to improve your English is to get out into the real world, have fun, and make plenty of mistakes.
It’s easy to spend all of your social time with others at the same language level, or others from the same country as you. Beware of this! It can stunt your improvement in English. The more native speakers you befriend, the faster you will improve your English.
