It's confusing, yaar—they take your raw score from one session and then rank it against everyone's scores from all sessions to make the percentile. Honestly, the obvious advice is to focus on the highest score, but retaking it shows you that the session you get matters too; my physics paper last year was unfairly tough and it changed everything. My real study is comparing my two hall tickets side-by-side, hoping for a gentler set this time.
