As a music student about to do his Grade 5 theory exam, I would say this is a very helpful aid in studying for it. This book, along with the other theory workbooks for grades 1,2,3 and 4 take in everything that could come up in the exam. The books are very thorough and detailed, with exercises on everything from key signatures, chords and their placement at cadential points to composition, all of which are examined. At the end of the book are some exercises which are laid out in the test format for extra practice. From a students point of view, their detailed exercises are very tedious, but they have to be done to prepare adequately for the test. A good investment for those doing the ABRSM Grade 5 theory test.
