With the cost of college rising rapidly, it can be overwhelming to think about how to pay your way through school for either yourself or your kids. Fortunately, saving hundreds, or even thousands, is possible. Teenagers can help keep down the cost of their future college tuition by taking the following classes and exams while in high school:

• Advanced Placement (AP) classes and exams provide the opportunity for high school students to take college-level classes at their high school and an exam at the end of the school year. Many colleges will accept AP credits as placement and/or college credit. Most will accept a passing grade of 3, but some universities may require a score of 4 or 5 to earn college credit. (AP exam scores range from 1 to 5.)
• College Level Examination Program (CLEP) tests also offer the opportunity to earn college credit by passing an exam. However, instead of taking a class, you must study on your own and schedule an exam at a testing center when you’re ready. CLEP exams receive a score between 20 and 80. A score of 50 is typically the passing score to obtain college credit, but each university sets its own requirement. It is important to note that while many colleges accept CLEP credits, some top schools do not.
• Dual enrollment classes allow high school students to take college courses at a local college or university and earn both high school and college credit. You must be a high school junior or senior to qualify for the program. Dual enrollment credits are widely transferable.

Cost of Exams and Potential Savings

AP exams cost around $100, while CLEP tests cost $93 plus an additional administrative fee while dual enrollment programs pay for tuition, fees and books. According to the College Board, the average cost of a 3-credit class at a four-year college ranges from $1,200 to $4,500, meaning for each 3-credit class you test out of, you save hundreds—potentially thousands–of dollars!

Additionally, earning college credit in high school can enable you to finish college in less than four years. Just make sure that when you’re choosing a college, you pay attention to whether or not the schools accept AP and/or CLEP exam scores as credit.
