I was trying to compare the initial KE/PE with the final KE/PE in order to find out how far the skateboarder rose but the solution was wrong for some reason?

Keep in mind the skateboarder is traveling along the HORIZONTAL portion of the ramp at 6.5m/s so when he gets to the top of the ramp he will only be traveling at 5.77m/s by my calculations.

Somehow, the skateboarder's initial horizontal velocity morphed from 6.5 m/s to 6.8 m/s in your calculations of KE/PE. Bad handwriting, perhaps?

WOW, thanks so much. I was killing myself over this question and probably spent ~3 hours trying to rack my brain around it even though it's basic physics.
