When Not To Use The Article 'a'.
Hi teachers!
How is it going?
"Doing more exercises are key to achieving a high score."
1- Please, I want to know whether it's possible to add 'a' before the noun 'key'.
2- If so, would it have the same meaning as if it were without?
3- If not, how do I know that in such sentences, I shouldn't add "a"? Is it because the key here is not physical, so any noun that doesn't imply a physical meaning ( like knowledge is key), we should use it without 'a' article.
Thanks in advance

" Key here is used as an adjective, meaning important or critical or necessary. It is a general concept, not a physical key to unlock some door. We would never write: * Doing more exercises are a important to achieving a high score.
