There isn't a test you can take here. There are tests online that you could probably look into that would estimate your level. However, unless you've taken a more official test that accurately tests your level in any given language, you simply have to estimate it for yourself based on what level you feel that you are at. Do some research over the Common European Framework of Reference for foreign languages (CEFR) and you'll get a description of each level. This is the level system that ITALKI uses in their profile settings. Find which ever level best describes you and choose based on that.

hi, I teach you spanish and you teach me english by spyke, what do you say about it? :-)

You can look at the Wikipedia page for CEFR (Common European Framework of Reference for Languages), as there is a fairly good description of what a language learner is able to do at each level.
