You could get all 9's but it's not a realistic goal. If you get at least 2 9's, that's just beyond amazing. Tbh, I'm not that keen in the new 9-1 system, only because they separate the A* grade into level 8 and level 9. It somewhat tells students that even though you achieved an A*, you haven't got the highest possible grade. Getting an 8 should be an incredible achievement. These grade 9's do put some students down if they don't achieve it.
