Start with our Standard version — it's FREE! All colleges using the Common App® will require at least those sections that are covered in the Standard version. That might be all you need, in which case you won't have to upgrade at all. Some colleges require additional sections (like essays and college supplements), and if you want help with those, you can always upgrade from within the Standard version. You can wait to see if you even need those extras before upgrading.
If you already know you'll want more than the Standard version, you can purchase the Plus, Pro, or Ultimate version from the beginning.
