Why do you think you're still Pre-Grade 1 lol!

Only joking! I practise for a reasonably long time, but often find I spend more time off-putting my scales so I can play pieces instead! How many scales do you have to practise lol?!... well, first there's all the ascendings and descendings... 12 majors, and 24 minors... then there are the contrary motions...12 majors and 12 minors (you don't get contrary minors I don't think?!), then all the arpeggios...12 majors and 12 minors... and if you want to count the broken chords (I think that's what they're called, can't remember!) an extra 12 majors and 12 minors! Umm... so calculating roughly
108 scales!!!! And if you happen to play that big book of Hanon exercises (if you play piano), you'll get an extra 60 exercises more!! So, the big number is
168 exercises! And thus you'll find you don't have much time to do anything else for the day!
