It’s a personal decision, but I think it’s not a bad idea to repeat. There’s no rush to get through your high school years. Being away from home for school will presumably be a new experience for you and the work expectation is often a jump too. You can take advantage of the 9th grade programs (many schools have special opportunities for 9th graders) and have more time for electives as you progress through the 4 years. When my son applied last year, his educational consultant told us that it is easier to get into schools for 9th grade than 10th grade. Again, that is just in general, and you have to decide what is right for you. There is no right or wrong.
