I didn't think there were any 6 markers.
There are shorter 1-3 ish markers, in which case you need to just make 1-3 short points.
The essays are 8 and 15 marks. You need to make points on either side of the argument. You need a valid conclusion. If it states "refer to the sources as well as your own knowledge" then do make sure you do that - say what the sources indicate, and add your own additional points too.
