Where can I find free IELTS Listening practice tests with an answer key?
The test owners publish practice material of their own. The British Council's free Listening practice tests give you a full test across four pages, with a question paper and a blank answer sheet to download, and the answers published so you can mark your own work.

The official IELTS site also publishes sample test questions with answers, a second set once the first is finished.
Whichever set you use, the key itself decides how much you learn. Published keys print alternatives separated by a slash, so Unit 15 / Unit fifteen means either form earns the mark, and words in brackets are optional, as in (a) barrier or (certain) disease(s). Before you trust a third-party test, check three things: whether the publisher behind the test is named, whether the key shows alternatives rather than a single form, and whether each question set prints its own instruction line. Without that instruction line you cannot tell which word limit was tested, and the marking of your own answers becomes guesswork.
