It was the final of Child Genius on Tuesday, when five young finalists were whittled down to just one champion through an exceptionally tricky specialist subject round and a final head-to-head.
Those battling it out were siblings Stephen, 12, and Georgia, 10, from Birmingham, Rhea, 10, from West London, diminutive Saffy, nine, from Surrey, and 12-year-old Jonathan from Gloucester.
But the wonderfully intelligent kids were overshadowed completely by their amazingly pushy parents, in particular Rhea's mum and dad Sonal and Anish.
Sonal, who gave up her job as a obstetrician to train Rhea, giving her up to three hours a day of extra homework, caused a stir on the show when she questioned one of the incorrect answers Rhea had given.
In her specialist subject round of Florence Nightingale's influence on military and healthcare reform, Rhea answered Dr Duncan Menzies to the question, "To which medical officer did Florence Nightingale report to in the Crimea?" which wasn't what quizmaster Richard Osman had on his card.
But mum Sonal went to the adjudicators and got them to accept the question was "too general" to bring her neck-and-neck with Saffy on 16 points and see her through to the final.
Some viewers praised the "tiger mom".
Said it last week and saying it again; Rhea's parents are on point #ChildGenius

Rhea's mum is proof that sometimes you really just have to go and push for what you want and you might just get it! #ChildGenius

British parents would be too modest and polite to challenge the adjudicator #childgenius

But some were very against her actions, which meant Stephen was knocked out the competition.
I realise this isn't a controversial opinion but most of the parents on #ChildGenius seem to be doing more harm than good for their kids

Parents just cheated another kid out of the competition, how grim #ChildGenius

#childgenius if I was the adjudicator I'd say ' thanks to your parents interfering you are now disqualified' ?

But everyone was in awe of the kids.
If I studied for the rest of my life I couldn't compete with these kids. Impressive stuff #ChildGenius

Both children in the final of #ChildGenius are amazing regardless of who got to the buzzer first.

Although parents at home were just as happy with their own kids.

In the end, Rhea went on to win the competition, with just one more point than Saffy.
