Studying abroad directly? Or go to an international school?
In any case, first of all, you must obtain a degree recognized by the school studying abroad. Generally, domestic ordinary high school diplomas are not recognized abroad. If you need the corresponding diploma, you must go to an international school, otherwise you will take many detours. Of course, you can also go to a foreign preparatory school for one year after graduating from high school, instead of going to an international school for the whole high school!
