Each question has
a musical segment of 3 notes and therefore 2 intervals.
Click the question number to hear the segment,
then click a radio button on the top row to identify the first
interval
and a radio button on the bottom row to identify the second
interval.
When you are done with all the questions, click the 'Submit
Test' button.
You will then get a message indicating which (if any) intervals
you need to study more based on your answers, and an 'x' will
appear next to the question(s) where you made one or more errors.
