English as a second language online

Using English is an important resource online with a large collection of English as a Second Language (ESL) tools & resources for students, teachers, learners and academics, covering the full spectrum of ESL, EFL, ESOL, and EAP subject areas. You can find tests and quizzes, handouts, printables, scientific articles, blogs and an interesting teachers forum. There's also a section that we found particularly interesting on English  idioms and idiomatic expressions. Give it a try!
