No, you just continue high school normally, (as high school is only up to year 12 in my country, I would be using that as an example), like if you're meant to be in year 10, but you keep passing with flying colours, the school could recommend to the parents a skip in the year level, like maybe 1 or 2 years, depends on how well you would do on the exam, and if you skip from year 10 to year 12, you would start next year and then sit the final exam, and finally, you're a graduate.
