When arriving at question 15 of 15 (the last question in a series of customized rhythm exercises), it's not possible to retake the question to try and improve. However, it's possible to do it with all of the 14 other questions.
Is there a way to enable "ti tiri" / "ti tika" and "tiri ti" / "tika ti", but disable the sixteenth - eighth - sixteenth rhythm pattern in the rhythmic sight reading exercises?
And / or isolate the latter rhythm to practice separately with for example just quarter and eighth notes?
