@alisadeghian1372,

I'm a bit confused by your comment. We don't run the registration procedures for the HSK exam -- that is usually handled by the various institutions paid by Hanban, so if they have deadlines we cannot help with that. Was there something specific that you needed?

Generally, if you're looking for background information on the HSK exam, copies of the wordlists and/or tips on how to prepare, you might want to take a look at our page dedicated to the HSK test. If you visit our study center and scroll down, the last paragraph has links to test questions which might be useful as well.
