My suggestion is to wean yourself from Alfred and start with simpler "real" music. Though Alfred is good to start with for beginners, you want to get out of it as soon as you can. At Grade 3, you can try Anna Magdelena's Notebook, Beethoven's Dances, simpler Clementi or Kuhlau sonatinas and Burgmuller Op. 100. For exercises, try some Czerny studies. Hanon can be dry and boring; and learning all those patterns lead to "no-where", whereas Czerny's exercises are more functional, and the techniques learned are used in many classical pieces. Your teacher will be able to advice you with better repertoire and pieces. Best of luck.PS. And your age makes no difference!
Sorry to be a pain but in regards to Czerny exercises, could you recommend a suitable book for me?
No pain! Well, for grade 3 level, start with Op. 823; (and eventually work you way to Op. 299). Remember that you do not have to do every one of them.
Yay!! Remember you do not have to go through each one. Many are similar. Find the ones that interest you and jump right in!
