Master of auruls eh? No offence but you auruls is ok in Grades 1-6. In Grade 7 and 8..........it's horror! In grade 8 it's crazy, sing the LOWEST part of a 3 part phrase and sight sing the lower part while the examiner plays the upper part. Then, identify the cadence, and the last chords. Eg:iib, Ic, V ,I ...etc. Finally, tell the examiner alll u can about a piece the examiner plays. Not so easy now....*wink*

Anyway, there's some people aurul gifted but majority not. In grade 1 I got full for aurul but in Grade 7 , it's ######. Doing Grade 8 this year.
ANyway.........back to the topic. Good to know that u r keen in piano. You can get to Grade 1 very fast. May be in 1 month.U can do it since you already have some musical background. GOod luck!

Hopefully u get a dis. in G.1 piano.
