Yellow braiding on blazer

What if l got all 100% in biology,chemistry,geography,maths,English and Mandarin do you think that they would give me the yellow braiding

And participate in the international biology olympiad

Which part does the school recognize

One of my friends asked because she participated in the international biology olympiad

what yellow braiding for? Im scottish and confused

it's for participation in long term activities and leadership when you are in S5 S6 you usually get them in school.It shows importance

When I started s6 we got red braiding on our blazers but it was purely for being an s6 not long team activities
