hello, does anybody have any website or cheap/free app suggestions for music theory.
We have some books already for gr1, 2 and 5 and could do with not spending too much money on any more.
When all told if you buy the resources and have paid for the exam there's not much change from £100, and they say music isn't elitist. 
I hate the fact you can get free past papers for GCSe, A level, SATS etc but music theory you have to pay.
Any suggestions gratefully received. I have tried the ABRSM sales and even Amazon aren't much cheaper.
