Samantha Lewthwaite told The Bucks Herald she was ‘surprised’ to achieve an A grade in A-level religious studies in 2002.
The Muslim-convert is wanted by Interpol on charges of being in possession of explosives and conspiracy to commit a felony back in December 2011.
The ‘white widow’ has also been linked to the terrorist attack in Nairobi earlier this month, although her involvement in this has yet to be confirmed by authorities.
Lewthwaite took A-levels at the Grange School in Aylesbury in 2002 and was singled out for praise with eight other students by then-headteacher Alan Silver.
The Herald said that ‘Samantha, 18, will be studying at London’s School of Oriental and African Studies next year, following her grade A at religious studies and grade C at history’.
She had told The Herald: “I’m surprised with the religious studies one. I’m really pleased.”
Lewthwaite also took an A-level in English language but it is unclear what she was awarded.
Mr Silver said of his school’s performance: “These results are largely as expected and show that the pupils at The Grange School have worked hard these past two years and achieved the level of success of which they are capable.”
He gave a list of nine students ‘we are particularly pleased with’ which included Lewthwaite.
Lewthwaite, now 29, was married to 7/7 suicide bomber Jermaine Lindsay.
