Usually when exams trend on Twitter, students complain about the difficulty or unfairness of the paper.
But when a GCSE Chemistry paper, set by AQA, started trending, it was for a very different reason.
The C2 exam formed part of students' 'double science' GCSE. Many teenagers find science tricky, but luckily for these students, the questions seemed easy.
The so-called '6 marker' was especially easy, apparently.
However, students that study triple science had to stay for one more exam: C3.
Unfortunately for them, C3´s questions weren't so nice...
And there's still one particularly tough exam left...
