I think you don't need ''study hardly'', because like that will be really difficult to you, so .. it is better you learn with something that you like, how musics, series, chat, articles, settings in english, these things, so if you do it everyday just a little you'll to better much. =)

study hardly

First of all improve you vocabulary. The more you can improve your vocabulary it will be much easier for you.

There are many sites, so use more than one. Use a good online dictionary and translator, but remember they are not perfect! A great thing to do, is look at the lesson corrections of this site and others. Look at how things are said.
