A GIRL aged just 14 has scored a top grade in her maths GCSE, – with only two weeks to prepare for the exam.

Sona Mistry scored an impressive A grade in the subject at New Charter Academy in Ashton, but she only found out two weeks before she sat the exam that she’d made it onto the list of candidates.

Sona’s journey to her early GCSE success started last year when her older sister sat her GCSE in the subject, and Sona, who has always loved maths, started to look through her revision guides.

Thinking she could answer some of the questions, she mentioned it to her teacher and just two weeks before the exam Sona was told that she’d be sitting the exam along with students two years older.

"I was really surprised, I didn’t think I would get that (an A grade)," said Sona, who is also keen on classical and Bollywood dancing.
