If you are putting students through grade examinations in theory in exams from the ABRSM, Trinity College London or the Australian Music Examination Board (AMEB) then these books align perfectly with the grade levels.
We recommend that you still use official publications and trial exams from the relative examination board, however the books cover all the content required.
If you are not doing grade exams with the students then these books still provide a great opportunity for them to cover everything they need to know.
PLUS you can legitimately increase your income by printing out these workbooks and selling them onto your students. You can charge them less than the price in the shops, give them a better product and make some money at the same time. Everyone wins!
