Pupils at a north Wales school affected by an examination board mistake are celebrating after receiving top marks in their A and AS-level examinations.

The papers from 19 AS-level students at Ysgol Brynhyfryd in Ruthin were among 300 thrown away after they were delivered to the wrong address.

It emerged last month that papers for a sociology exam set by the Oxford, Cambridge and RSA Examinations Board (OCR) which were supposed to go to the home of a marker, has ended up at a neighbour's house.

However, head teacher at Ysgol Brynhyfryd Eleri Jones said students had not allowed the mix-up to cloud their day.

"That was extremely frustrating in terms of students realising that after all their hard work for that specific paper, it will never be marked.

"They will never actually know how well they performed in that paper.

"Clearly they have been awarded grades which have been based on their teachers assessment and also their performance on the other two papers."

Emma Davies from Ruthin was one of the students involved in the blunder.

She said the examination boards mistake did not concern her.

"I'm quite pleased with my AS result - I expected it to be worse, I'm not bothered about the paper mistake because I got a B so there's no point complaining."

Excellent grades

The 18-year-old added: "I got an A in A-level English, B in media, C in art and two B's in AS-level sociology and general studies.

"I'm going to study English and Psychology now at Liverpool."

Ms Jones said staff and students are overjoyed with the results: "These are the best A level results in the history of the school with 100% pass rate at A-E grade and 89% passed at A to C."

She added: "Statistically, the girls have outperformed the boys but we have had more A grades amongst the boys."

Liam Burn and Thomas Fay were two students who received straight A grades.

Nell Cattell plans to travel

They both got into their first choice of university to study music and history in September.

Eighteen-year-old Nell Cattel from Denbigh achieved three A grades in chemistry, biology and maths.

She said she was shocked by her grades: "I just didn't expect to get these results."

"I'm taking a year out to go travelling and decide what I want to do."

Students across Denbighshire have received excellent grades with 98.1% of pupils in the county's eight secondary schools gaining A-level passes.

Wrexham council have said that although not all the results have been analysed, early indications suggest that the overall pass rate is around 97%.

Pupils using the Welsh exam board, Welsh Joint Education Committee(WJEC) in Flintshire have seen a 97.4% pass rate.

Education officers say that is an increase of 2.76% on last years results.
