Section A is all about reading. So as along as your punctuation, spelling and your key English terms are accurate you're fine.
For all of the 4Q mention (in Section A):
•Text-type
•Audience
•Purpose
•Occasion;
Do these all briefly but try to find multiply-purpose and multi-audience.
For:
Q1- just find and select the information relevant to the question and write it out in a good order
Q2- identify the main layout points, so headline, strapline, subheadings, pictures, boxes (with quotes or information) and link the effect of them back to the overall points (text-type etc)
Q3- identify atleast 4 points about language within the text, and mention the effect to the reader, and how it 'fits' in with the the whole idea of the reader (for example, 'saying that Democracy is a 'waste-of-time' forces the readers biased opinion onto the reader and this fits in with the overall purpose of the writer belittling Democracy. However the writer simply could be trying to make a pun to take advantage of his anti-democracy readers').
Q4 - use the information and answer from Q3, and the other text should be the one where you see more difference or is simply more complex and long. For this mention the main points for both, then mention a point about one (use the technique from Q3) say how it differs but is somewhat similar (don't give a simple answer such as 'it is because'; use 'it could be because' or 'the writer may have been' to show overlap) and then link the reasons to the main points of the two texts. Try to mention as many point, at least one linking back to each text-type, audience, purpose and occasion.
As for section B the key thing is to use methods you've seen in section A and elsewhere and implement them within your text as required. Q5 is usually quite broad and allows your to write about anything within a large area, such a protecting the environment or a hard decision you had to make, so you need to either use the inform or possibly explain/argue techniques. For Q6, this will usually be a longer, more detailed writing required such as a piece to change opinions, persuade, so the techniques need to be more 'severe'.
Hope that helps :')
