Meeting his parents..?

so i've reached the stage with my boyfriend where we're planning the 'meet the parents' meal. I'm really worried because my boyfriend is like.. perfect. Went to a grammar school, got all A's and A*'s in any exam he's ever taken and is a very academic person, he also does loads of sport, he does loads of volunteer work and has a really well paying job, he's really funny and chatty so i'm really not fussed about when it comes to meet my parents. My issue is that I didn't go to a grammar school, I got mixed marks at school, i'm not an academic person i'm into art and fashion, I have a part-time modeling job that doesn't pay that well. I'm just so worried because I already feel inferior to him and I know his parents will feel the same and wonder why he's with me. How can I impress them?
