BBC Bitesize is good for Nat. 5 English Scottish Texts and I would encourage pupils to access the SQA website for practice papers/ examples re. both Paper 1 and Paper 2.

Most importantly, pupils should re- read their Scottish texts and other literature which has been studied for Critical Essay purposes and read any Notes already given to them by their English teachers.
SQA’s Understanding Standards web page for exemplification of the different elements with commentaries and marking guides. To familiarise themselves with the course, parents and carers can look at the SQA’s Candidate Guide.

If the class is doing any Shakespeare text, “No Fear Shakespeare” is excellent.
