BRITAIN'S smartest teen who is sitting 28 A-levels has scored A*s in the ones she completed just weeks after the start of the school term.

Mahnoor Cheema, from Slough, has an IQ higher than Stephen Hawking and Albert Einstein - and has her sights on studying at Oxford University.

After sitting 34 GCSEs, the 17 year old began sixth form in September, and enrolled on 28 courses.

She completed four entire A-levels in November and has found out she scored four A*s in environmental management, marine science, English language and thinking skills.

And she's sitting the final exams for eight more courses next month - including maths, further maths, chemistry, biology and film studies.

She says she has no regrets and would be "bored and understimulated" if she only did the standard three A-levels - and said burnout is "a choice".

The grammar school pupil, from Slough, said: "Absorbing content and analysing and evaluating things comes naturally to me.

"I'm busy but I don't take on so much that it’ll cause me stress or pressure - I try to do everything within my capabilities.

"I have loads of interests, that's why I wanted to do so many subjects - it doesn't take that much time or effort.

"I think if you have the capability to do more, it should be explored - I would be bored doing only three subjects over two years.

"Burnout is a big thing for some people but I'm just motivated and driven and it doesn't affect me.

"I see burnout as a choice - it's not burnout if you enjoy what you're doing."

Mahnoor was born in the UK before moving to Lahore, Pakistan with her parents in 2010.
Her family then moved back to the UK in 2016 and mum Tayyaba Cheema, 43, a full-time mum with a masters in economics, said she Mahnoor "quite different" from a young age.

By the age of six, Mahnoor had read all seven Harry Potter books, and, by 11, had learned the entire Oxford English Dictionary "by heart".
She studied 24 GCSEs in her own time alongside 10 at Langley Grammar School and scored 33 nines and one eight - equivalent to 33 A*s and one A/A*.

Mahnoor, who dreams of doing a TED talk one day, said: "I just read the book and it goes into my head.

"I don't really take notes - I find them to be a waste of time. I don't think my memory is photographic, but it's good!"

As a budding medicine student, her favourite subjects are maths and sciences but she's also studying film studies and French.

She said: "The main enjoyment for me is studying the subject and the rich knowledge - the exam is just the qualification.

"A big misconception is I'm just an exam robot, but loads of the subjects I do require analysis too.

"For film studies, I have to create a film, edit, write the script. And with English you have to develop your own critical stance."

Mahnoor has an unusual sleep routine - going to bed for three hours after school, getting up at 7pm, and going back to bed at 2am.

Tayyaba creates a study timetable for Mahnoor to keep her on track, making sure she makes time to see friends, travel and enjoy hobbies.

But Tayyaba, also mum to Laila, 14, and Jibran, 10, said there is "no pressure" from her or her barrister husband Usman Cheema, 48, for Mahnoor to do anything more than what she wants to.

Tayyaba said: "I have given her the choice, I just say 'whatever you do in life, do it the best you can'."

She got her recent four results in January.

Mahnoor is currently still studying psychology, sociology, law, business, accounting, economics, Latin, German, computer science, film studies, politics, classical civilisation, maths, further maths, geography and media studies, physics, chemistry, biology, English literature, film studies, French, statistics and accounting.
