Achieve helps adult learners earn their online accredited college degree at 1/2 the cost and time of traditional schools. We help you test-out of college classes rather than taking them. LPN to RN, Nursing Degrees, CNA to RN, Med Asst to RN all available. History Established in 2008. In late 2008 Achieve Test Prep began teaching courses to help LPNs earn their RN degrees. What started with campus based locations has grown to include online virtual classrooms with the same great teachers but you can choose to learn from home or anywhere you can get online. Now we help CNAs, Medical Asst, and most anyone earn their RN or any college degree by testing-out of classes.
