You can, that is why it is called an accelerated program. But if you are acutally 16 as your post states, you would be much better off going directly for your BSN.. If you select to go the ADN route, remember that even those programs are listed as two years, most require you to have many pre-requisites done before you can even start, so many that get an aDN have actually put in minimum of three years. Something that you need to pay close attention to, plus the accelerated programs are usually much more expensive than the regular programs.
Hope that this helps......................
