bullet1 Number of noun

Your feedback says:

NUMBER OF NOUN - you have put a word in the singular when it should be plural, or vice versa. Or perhaps the noun is countable and you thought it was uncountable, or vice versa. Check that you have used the right article, as well.


So what’s the problem? And what do you need to do?

Check if nouns are countable or uncountable, and if you put plural or singular forms.
