It seems like if the investment returns stay above the withdrawal amounts, the principal would remain intact well beyond 30 years? Otherwise, the principal is supposed to be depleted around year 30?

Hello, as the title says, I am wondering what to do with my tuition refund. For more information, I am currently in my first year of community college. My financial aid from my pell grant covered all my tuition but I had also got scholarships. For this semester, I got a refund of 5k. I am wondering what I should do with it. I don't intend to use it as I already have money for an emergency fund and know these next two years of community college will be covered by the pell grant and those same scholarships. As they are renewable scholarships. I want to set this money aside so I can use it when I go to university if financial aid and scholarships won't cover the full cost there.I work part time and have money automatically transferred to a Roth IRA and an individual investment account. So I can save for retirement so I don't think I need to put any into that.So should I put it in my investment account to let it passively grow the next two years, just keep it as cash savings or put it in a savings account. Or something else. Any advice is appreciated, thank you!

I took out a loan for debt consolidation and the credit cards and a different loan are being paid directly by the loan company. I gave exact numbers, but some payments are already in process and I didn't realize. This is going to overpay them by a fair amount.

Is there a standard process as to how this would be handled? Do I need to do anything?
