This question is an exact duplicate of:
- Have and have got 1 answer
Do the Britons (British people) say both?
And, I've found it from the book that said:
"Have got to" is more informal than "have to", so do Britons say this:
- I have to get a great score than last exam. (AE/BrE) is this common in BrE?
- I have got to get a great score than last exam. (BrE) is usually used in speaking.
- I gotta get a great score than last exam. (Informal AE).
So, the question is which is more preferred in BrE, in spoken and written BrE?
