The impact will vary by child. I had a good friend in college that skipped a grade around this same period in his education. He was academically ready for college but not so socially or emotionally. It seemed like he was OK at first, but the pressure of college just caught up with him. He took a year off and came back and did very well.
Another person I know that skipped a grade did just fine.
As others have said, the colleges will look at what you’ve done and not your age.
But the real question is why rush things? Are you really looking to move on to the “real world” and all its responsibilities as fast as possible. Take it easy, slow down. Take other classes that fuel your passions. Enjoy the ride.
