Hi Miriam, Well, that depends on what you are looking to improve. For English, speaking, reading & writing are the basics. Reading, writing & grammar can be studied on your own, there are many "free" resources on the internet. However, speaking must be practiced. A teacher will be able to correct you with pronunciation, intonation and grammar mistakes. Check out my profile and if you are interested, I'm sure I can help you improve your English. Anything that you consider studying will take time and discipline. Good luck!
