To clarify...
In Higher English:
Folio= 30 marks (15 marks discursive/persuasive, 15 marks creative reflective)
Paper 1- RUAE= 30 marks
Paper 2- Critical Reading= 40 marks (20 marks Scottish text,
20 marks Critical essay)
Total= 100 marks
The biggest tips I can give you are...
Use a few key quotes relevant to the question (you don't need dozens of them- I would say include about 1/2 per paragraph)
Make sure you use topic sentences
Have a good introduction (it helps to almost have a template for this and just change it slightly in the exam to fit the question)
Analyse all of the quotes that you use- this is super important- fuller analysis will get you more marks
At the end of each paragraph, the last sentence or two should relate the paragraph back to the question, almost summarising how the point you made in the paragraph answers the question
Again with the conclusion, have a rough template of what you will use, so you don't need to think it up in the last 5 minutes of the exam! Make sure you bring together what you have said in the main paragraphs and be sure to answer the question in the conclusion!
Hope this helps
