Typically, you will be prompted to pay for the exam when you schedule the exam. When using ProctorU or Examity, there is a fee involved. If you are using a face-to-face proctor or a testing center, you may or may not have a testing fee depending on whether the proctor accepts payment at the proctoring location (which will be indicated in the proctor's profile) or if they offer free proctoring.
