Can you choose to do dictation only?
Is there a way to select which type of exercise you do? I would like to be able to only do dictation exercises (i.e. listen to Spanish and then type what you hear in Spanish.) This is because I am already fairly familiar with the language, but want to focus on my listening and writing.
Not yet, but I second this feature request.
I would like to have a check-box toggle in the Settings section to enable or disable particular kinds of problems in practice and lessons. For example, Duolingo isn't currently very Deaf-friendly, because although you can disable the speaking problems by turning off the microphone, you still can't eliminate the listen-and-type problems.
