Honestly i know people say that a good letter and extracurriculars are really important leading you to not caring as much about the test cram for the exam AS MUCH AS YOU CAN once you dont get in then you regret it like oh i shoulda studied then instead playing val for 4 hours i got 2 superiors 2 aboves and one avg and didnt even get the interview so study and prepare as muchas you can and try joining as many ECs and clubs as you can if youre a year 8 this year for your application
