It depends what it is for me but text can be frustrating for learning. I don’t retain read information well, I read slowly, I get distracted and can’t multitask to focus when my eyes are locked up with text, and it all kinda blurs together and feels samey. With audio I can set it to double speed and still process well making it way faster to process than my read speed, I can multitask to stay focused better, I’m less likely to get eye strain, retain the info better. With audio and video I can link changes in the screen and audio in a broad sense to what was being said. Like “oh this part where the music changed right before switching from the three paragraph page to the four paragraph page is extra important” which helps me retain the topic while also giving me clues as to where to find information without running into all the text being samey
