Anonymous question statistics

When you submit with statistics on, your answers add to totals for each question version: how often it is answered correctly and time spent on it. Broad score groups from the other answered questions help us check for a possible wrong answer key. We keep the combined totals, with no submission ID or list of your answers in these statistics.

These totals have no name, email, account, IP address, device or browser details, or time of day. Your scratchpad, eliminated options and flags never leave your device.

We use these statistics only to estimate how hard each question is and to find questions that may be wrong. We keep these question totals indefinitely.

The totals combine contributions from different learners, so we cannot remove an individual contribution later. If you don't want to contribute, turn off Share anonymous question statistics before you start. The exam works the same either way.

What else is sent to us

  • When you start a set, check a practice answer, move on in an adaptive exam or submit, the page sends the set's sealed code and your answers. The server sends back the next question, or the answers and explanations.
  • These requests carry no name, email address or sign-in cookie.
  • To keep an answer from changing once it counts, the server keeps a note of your first answer to each question, of each question an adaptive exam served and of each scored set, under a code that says nothing about you. It deletes the note after about a day.

With an account

When you are signed in, each question you answered in a finished set is added to your study history with the day you finished. Question timings are left out. These answers count toward your skills on Progress. The privacy policy covers the account.
