SQL Proficiency

Hi,

I recently started to learn about SQL to develop my skillset a bit. So far, I have started with and completed all the SQL tutorials over at Tizag (Couldn't post the URL since I'm new user sorry).

As I am still new to SQL and do not have an appreciation for its full scope, can someone please identify for me what level of proficiency you would say I am at after completing the tizag tutorials? Basic understanding, beginner, intermediate etc. ?

I have already found a couple good learning resources, but if you have anymore to throw my way, please do. Especially if they involve real world exercises on a database I can import.
