It's getting to the business end of the University Challenge deal and the weekly contests are getting ever more tense, as the latest match - between St John's Cambridge and Balliol Oxford - proved.
Dubbed 'the boat race battle' on social media, the Monday night contest between two of the UK's top universities left viewers on the edge of their seats during an encounter that saw the two brainbox teams neck-and-neck throughout.
Quizmaster Jeremy Paxman seemed just as enthralled as fans of the BBC2 quiz show when, with just five minutes to go, the teams were level pegging, with Cambridge appearing to be the more likely winners.

In the end, however, it was a knowledge of birds that propelled Oxford Balliol to grasp victory, pulling away in the final minutes of the programme to win 200 to 155 after a bonus round on ornithology.
Paxman asked Balliol: 'Which flightless bird is the second largest living bird after the ostrich?'
The answer, emu, saw the Oxford team stretch ahead, and they didn't look back, with Cambridge failing to score another point.
Paxman, still sporting bouyant lockdown hair as the episode was filmed during the first lockdown, told Oxford 'you just got in under the wire there' as they fired off a series of correct answers to swell their score.
It's emu! A question about flightless birds saw Oxford finally gain the momentum to win
