How good is my ASVAB score?

I just took the ASVAB today at MEPS, I get sworn into the Marine Corps next week and go to boot camp once I graduate high school. My ASVAB score is 80. Is that good? My recruiter says it's really good, but I want to be sure. Once in the Marines, I want to EARN THE OPPORTUNITY to try and become Force Recon or Sniper. But anyways, just, how good is the score?
