Acceptable and is now added as one of the solutions, thanks. Note through that there might be some delay before the course will reflect changes made in the Incubator.
As I was told, this isn't a very common thing to say, but it's okay. Added now.
"Much" alone as an adjective of an unspecified large quantity is indeed a very strange use.
I guess it's technically correct as long as it precedes a non-countable noun (vs. "many" for countable), but because far and away the word "much" is used in a negative sense in this context (I didn't make much food yesterday), its use in the affirmative sense causes some dissonance in the listener.
However, if you just add "so" to make "so much" and the connotation of negation vanishes.
