WJEC has sent a letter to schools offering to show them papers from January's GCSE English Language exam for 10% of pupils free of charge.
A small number of papers are being re-marked, because of inconsistency by one examiner - but WJEC said the vast majority were marked correctly.
The board said the move would be an opportunity to "illustrate" marks and grades awarded.
