Readabilty (Help!)

So I remember on here a little while ago that someone had found a website where you can enter a sample of your writing and it tells you what reading level it is at. I need that website. I thought I saved it, I didn't. And I so badly need that.

I've recently applied to SNHU online to get into their Bachelor's program for a degree in Creative Writing and English with a focus in Fiction writing.

Their journal for their writing students is holding a fall fiction writing competition and to be honest, I really need the scholarship money. I know that I can write something great, but I need to be absolute sure my writing is up to par with other college students because the scholarship money can be put towards their Master's Degree programs, which means it's not just a bunch of hopefuls like me who are entering.

Anyone have an idea? Anyone?

I'll be eternally grateful!!!
