Times they are a-changin'...and with that so are thoughts about college.

About one in five young adults of age say they may choose not to go to college. Many others see a less conventional path through education as a good idea. We're finding more and more college-age kids considering taking a gap year between high school and college.

The average borrower now leaves college with about $37,000 of loan debt, up more than $10,000 from 10 years ago.

“Rising college expenses are changing the modern college experience,” Luber said.

Just over one in four young millennials say they are delaying college due to the cost, according to the TD Ameritrade study.

About half — 49% — of young millennials said their degree was ‘very or somewhat unimportant’ to their current job.
