How do I complete this sentence?

[HomerBong]

I was doing an exercise involving use of English and i have to complete a sentence with 2-5 words without changing the meaning of the original sentence which was:
The alternative energy exhibition is opening in two weeks time.
I have to use the word until and complete this one:
It is two weeks .............................. of the alternative energy exhibition.
I was thinking about complete it this way. but I'm pretty sure it's wrong:
It is two week left until the opening of the alternative energy exhibition.
Any advices?

Your version is fine without 'left'.
