Is it possible to jump to grade 8 in trinity music exam without any proof or certificate of your grade?

Anything is possible, but this is unlikely. How do you master music? Practice, day in and day out.

How do you master music theory? Same way. Good lluck!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
