My name is Sarah and I am going to take the IELTS test in 10 days

I'd like to score band 7 or higher. However, my preparation for the test should be better.
I have finished my high school diploma something like ten days ago (it was a hard battle but i did it) and now, when most of my friends are enjoying their holidays, I am still studying. What about You? Is someone in my situation ( or similar) ?
Cheers,
Sarah.
P. S. I am taking the IELTS test because I am going to study ( or better, I'd love to study) Economics at the University of Edinburgh!
