Audio recording test doesn't seem to test anything
It appears that the audio tests don't really check whether you spoke properly or even said the same words as requested.
Given "La niña escribe una carta." I said "La niña bebe leche."
Expected: Failed question Actual result: Question passed (when it should have failed)
Speaking English doesn't work (it says "I couldn't understand you") but given "El niño escribe una carta" I got marked correct when I said "El niño doodle doodle doodle."
I think these practices should be removed or it should be clearly stated that this tool is NOT checking your pronunciation or even whether you are saying the words as written.
