online..umm not that i know of. but it is included in the piano syllabus of the RCM, look through there.
https://www.rcmexaminations.org/acadinfo/syllabi.htm#piano you can purchase the syllabus at the RCM music store
umm i'm currently working on my ARCT and it actually feels the same with any other grades. one thing i like about AR is that during the practical exam there is no listening/sight reading tests of any kind. it is like an individual solo concert for yourself in which you get to play all the wonderful pieces. the theory prequisites are, however, quite annoying. you must make sure you have passed all the theory requirements before you're able to take AR. this is important. -_-;;originally i was planning to take my AR this Aug but because i didn't have my 4history, my practical AR is postponed to Jan. they wouldn't let me take it even though i was enrolled as a 4history student at the RCM this Jul.
here is my repetoire list if you're interested
List A: BACH - Partita no. 2: Sinfonia
List B: BEETHOVEN - Sonata in Eb + Op. 31 no. 3 "the Hunt" (complete)
List C: CHOPIN - Ballade No. 1 in c- op.23
List D: GRANADOS - The Maiden and the Nightingale
List E: KUZMENKO (canadian) - In Memoriam to the Victims of Chernobyl
concert etude: either LISZT - Un Sospiro from Trois Etudes de Concert
or CHOPIN - etude in g# - op. 25 no. 6 (the one in 3rds)
or CHOPIN - "revoluntionary etude"
best of luck =)
