Advice pls! Korean Int. Stu. Wants to Study 1 more year to go to higher ranked college!

If money is the issue- why not work for a year while keeping her brain active instead of spending money without improving her financial situation?

You/she/her parents could check on transfer rates to elite schools. I doubt they are high enough that this strategy would work- especially for getting merit money. Many such schools may consider her college courses insufficient to handle their versions of follow up ones. She may need to reset her aspirations.
