If you have an associates degree now do to take another 4 years of college get a bachelors degree?

No, you would not need to take four full years to get a bachelor's degree if you already have an associate's degree. Many bachelor's degree programs allow you to transfer credits from your associate's degree. This means you could likely complete your bachelor's degree in less than four years, often two years or less, depending on the program and how many credits transfer.
