The Student Leaderboard
Here you can see the top 100 students in the world sorted by number of correct answers followed by total number of submissions.
The student leaderboard is updated only on Monday and is not "live" like the school leaderboards.
You can find the top 50 students in each year group on the results by year group pages.

There are more than 100 students who have submitted 100% correct answers so far so this is just the first 100 alphabetically by surname.
