Scenario I am confused about

Hi everyone,

I am applying this summer to seven different schools, and I am confused about how this will work. What if I get say 4 interviews out of the seven, and need to schedule interviews apart because either I got asked at completely different times or because of plane tickets. Well then I have heard you don't have that long to make a decision, but what if I haven't even gone to 3 places yet, and I got accepted into one. How do you make this work with that short of a time window to make a decision?
