Meet Britain's smartest teenager, who is aiming to complete 28 A levels - after getting 34 A*s in her GCSEs.<br /> <br />Mahnoor Cheema, 16, has already completed four A levels in just two months.<br /> <br />And she's hoping to study for at least 28 in total - which she believes would be a record.<br /> <br />Clever Mahnoor, from Slough, Berks., did 24 GCSEs in her own time alongside 10 at Langley Grammar School.<br /> <br />She scored an incredible 33 nines and one eight - equivalent to 33 A*s and one A/A*.<br /> <br />And she manages to squeeze it all in by using an unconventional sleep routine.<br /><br />Mahnoor said: "After school I sleep for three hours as I'm so tired, I wouldn't be as productive.<br /> <br />"Then I wake up at 7pm and go to bed again at 2am. The last hour of my day is spent playing piano.<br /><br />"But the most studying I will ever do in a day is two to three hours - it just comes naturally to me."<br /> <br />Mahnoor was born in the UK before moving to Lahore, Pakistan with her parents in 2010.<br /> <br />Her family then moved back to the UK in 2016 - by which time she had already shown huge promise.<br /> <br />Mum Tayyaba Cheema, 42, said she realised her daughter was "different" when the then one-year-old told her "I'm here for you" following a bereavement.<br /> <br />Tayyaba, a full-time mum with a masters in economics, said: “I got news from Pakistan that my father had just passed away.<br /> <br />"Mahnoor saw me and asked why I was crying, and I explained.<br /> <br />"She told me 'I’m here for you'. It just showed how sensitive and intelligent she was - even at that age."<br /> <br />Mahnoor then kept conquering complex tasks as she grew, according to Tayyaba and husband Usman Cheema, 48, a barrister.<br /> <br />By the age of six she had read all seven Harry Potter books, and, by 11, had learned the entire Oxford English Dictionary "by heart".<br /> <br />Mahnoor achieved her impressive GCSE results in the summer, for which she was praised by a former prime minister of Pakistan.<br /> <br />She achieved top marks in traditional subjects including physics, maths, and computer science - as well as Latin, Urdu, and Classics.<br /> <br />Mahnoor started her A levels in September and has already completed four - in English language, marine science, environmental management, and thinking skills.<br /> <br />She will get the results back in February.<br />
