I don't think certification can ever replace something like SATs to get into college. I however would never think that a certification could be a bad thing. The more information you get the better. I recently got my MCPD certification, and I recently went to a place called CED Solutions in Georgia. I've been to a few trainings before but the facilities here were pretty awesome. All the caffeine you can drink to keep you awake for those long 10 hour boot camp days.
That being said the level of effort they put in to ensuring that everyone got the most out of it that they could. I've been programming for a few years and still got a lot out of the boot camp I took instead of just a certificate.
I guess ultimately my point is that you should inundate yourself with the most information you can.
