The costs of college are one of the biggest obstacles to adults getting college degrees.

These days, public school students pay more than $32,000 for a 4-year degree. Here are some tips on how to attend college for free from Yahoo! Finance.

1. Tuition-free schools. A handful of colleges and universities don't add tuition to students' bills, which can add up to major cost savings for those who qualify.But most still charge room, board, and other fees, so they're not completely free.A few of the schools are Berea College in Kentucky and St. Louis Christian College in Missouri.

2. Do some online searching. Staying on top of the news may also help you come across free tuition opportunities. For example, a quick news search of 'free college tuition' leads to an announcement called 'Michigan 2020,' a new plan in 2012 that gives the state's resident high school seniors a 95-hundred dollar grant each year.

 

3. Watch for full scholarships at new schools. Keep an eye out for brand new institutions offering inaugural classes where they lure in students with free tuition deals.This is a great way to end up going to college for free.

4. Cast a wide ccholarship net. One myth many have about scholarships is that you need to be a top student or have years of community service to qualify, it's not true. And the Coca-Cola Scholars Program, for example, gives 20-thousand dollars to the top 50 finalists. You also want to apply for every scholarship for which you're eligible.

5. Join the Army. One final strategy for those seeking free tuition is to join the army.It's not for everyone, but there are various armed forces colleges that charge no tuition in exchange for active service after graduation -- including the U.S. Military Academy, the U.S. Naval Academy and the U.S. Merchant Marine Academy.
