Doctor Who series 8 premieres later this week, but how well do you know the show’s fourth series?

Here at Hypable, we love Doctor Who – and with Peter Capaldi’s debut as the Twelfth Doctor drawing ever closer we’re holding seven days of Tardis-centric festivities with Who Week. As part of the celebrations, we’re testing your knowledge of every series of the reboot era in the run up to the start of series 8.

The quizzes are especially designed to test just how astute a Whovian you are. So, they certainly won’t be easy. You’ll need to know every adventure of every series inside out if you want to achieve ‘The Doctor’ status on all of them.

Today, we’re quizzing you on Doctor Who series four. Airing in 2008, David Tennant’s final series saw the return of Catherine Tate as Donna Noble (now a fully fledged companion). It also saw the first (and last, story wise) appearance of River Song, as well as the return of friends in the form of Rose, Martha, Jack, Mickey, Jackie, and Sarah. There was also a more sinister return though – as Davros, creator of the Daleks, lurked in the shadows.
