Help!!!!!!!!! !!!!!!?

So, i got a newsletter form my school the other day, saying that there will be a "gifted screening process". And I'm in grade 7. I had the particular test in grade 4. But i moved right after and my results got forbidden and lost. I have an immense wish to go into the gifted cl. But I'm confused can anyone tell me all about it and can you do it after grade 4??? Tell me about the test please!
