Rules in this topic
3- A1
Capitalize I
Always capitalize the pronoun 'I'.
- A2
Apostrophe in negative contractions
A negative contraction needs its apostrophe: couldn't, didn't, doesn't — not couldnt, didnt, doesnt.
- B1
Could of vs Could have
Write 'could have' (or could've) instead of 'could of'.
