About 4 years ago me and my sister left the US to come to Bolivia, when I left I was in 6th grade. In Bolivia I finished 7th, 8th and 9th grade and now I’m in 10th grade, the plan was to go back when I finish 11th grade but my father wants me to go after I finish 10th, I was going to do it until I found out that there is a possibility that I have to repeat a year in the US because if I finish 10th and go to the US I would be 3 months behind, my father told me that I would just take an English test and continue the year but my sister’s friend told me that she needed to repeat a year when she got there.
Do I have to repeat a year? Or should I graduate here then go? Will it be harder for me to get into college if I graduate here? Please help me out, if you do not understand I will answer anything you ask.
