Are you currently researching colleges and career schools?
Not at the moment.
What is the refund policy if I stop attending classes before completing my course work?
If you begin attending classes but leave before completing your course work, you might be able to get some of your money back.
Is there a way to research a school without going there in person?
Yes, sure. Lots of schools offer virtual tours on their websites. You can see their campus and know more about the school without visiting in person.
And for the undergraduate programs, is there any test I need to take during the admission process?
You most probably will be required to take either the SAT or the ACT test.
Ok. And how could I research the school's reputation?
