For the AQA new English specification, our teacher has been teaching us a host of writing and reading skills.. but I read on the AQA website a few months ago that the questions are always the same:
Question 1: retrieving information from a piece of text
Question 2: analysing presentational features
Question 3: analysing the feelings/meaning of a text
Question 4: comparing/contrasting two texts
Question 5: writing to inform/describe/explain (although the question could ask you to do both)
Question 6: writing to persuade/argue
This is what I've gleaned from the specification and the AQA website; hope it helps!
