Remember, both exam papers will have a reading section AND a writing section. What makes the two papers different is whether they deal with fiction or non-fiction.
Exam Paper 1 deals with 'fiction'. Fiction refers to stories that aren't real. As a result, the reading section will focus on sections taken from stories/novels, while the writing section will focus on creating writing (writing stories or descriptions of locations).
To comfortably get a grade 4 (a grade C), we should be aiming to get at least 50% of the marks.
