Anyone who got a an A/A* in Gcse history could you give me some tips please? Watch
Start your paragraphs with your point, then provide the evidence and explain how that evidence fits the point, before then linking the point with your other points.
Have a range of figures and other things to throw into your evidence section. Also, practise essay writing and read examiners' reports to see what good essays look like and what the examiners are looking for. If on a new spec. then previous specifications should be fine for practise.
I also recommend past papers, loads and loads of past papers, they help a lot!
