My English experience.

I've been learning English about 5 years. I try to be an intelligent student but sometimes I can’t. In my opinion if you want to study English you should be hard -working obviously, and you should be eager, you know, you should be eager to study which means that you should initiate your study and then try to start learning by yourselves, not like depending on the teacher, and you know, just doing what you are told to do. I think you should have the motivation to study, so that would make a good student.

Another way of studying a foreign languages is how you learn the language. There are a lot of ways of studying English. Nobody learns a language the same way. As many people as many learning methods.  Try to combine the different methods and get a balanced approach.  You should do a little reading, a little writing, a little speaking and a lot of listening.  

If you have enough money the best way to learn a language is go to a native speaking country, and live there for a year or two. You can take a crash course of spoken English and immerse yourself completely into the language and the culture.

And of course you have to be disciplined and learn to manage your time. Don’t leave things to the last minute. It’s a good idea to do the tasks in good time.
