Every other part of the exam was grand enough but I only wrote like three and a bit pages in the composition part. I did the first one about the three greatest achievements in human history btw
Its quality over quantity. I got 80 on a 3 page personal essay before. You need about 1.5 pages for a 50 mark composition so 3 pages roughly for a 100 mark composition. People that write like 5 or more are either writing junk or lying.
Only got 3 pages done with very small writing - your question B will hopefully scoop the most marks and don't have anymore post mortems about the exams!
I heard you should aim for 700 - 1000 words. I wrote 780 roughly in about 3 and a half pages. Don't worry, if the quality is there, you will be marked as such.
