Ucas application

Hi everyone, UCAS want some scanned copies of my level 2 and level 3 qualifications.
And I gave the Information in UCAS that I am still in High School, I will graduate in June 2019. So is that meant my qualifications from 10th and 11th grade (high school) ??
And another university just want my "copies of your qualifications", so which qualifications should I send? All of the high school?
If someone had experiences with it, can someone help me please? Thank you!
