When referring to information students write down in classes/lectures, we normally use the plural form of 'note' - 'notes' tends to be used. But I am not sure whether 'notes' is countable/uncountable in this specific usage.
For example, should I use 'much' or 'many' if I want to ask someone:
"How much/many notes do you normally take during lectures?"
'Much' seems like the better option to me because 'many notes' sounds as though the student in question takes notes for multiple subjects. However, using 'much' would not be grammatical if 'notes' is a countable plural noun. In that case, should I use 'note' instead?
"How much note/notes do you normally take during lectures?"
Out of the 4 alternatives, which one is the most correct, natural-sounding question?
