FCE - Mistakes

Here are some mistakes that I have heard in class:

1. I wouldn't mind to see that film. Everyone says it's great.
2. People says that it was his best ever performance.
3. Have you seen George Clooney's last film?
4. What did you do for your holidays at the end?
5. I don't know what the exactly answer is. Do you?
6. We have the same teacher that last year.
7. All people in my office are working today.
8. I hope to become a lawyer after I finish my career.
9. Only a determined kind of person enters a reality show.
10. I am working as a lawyer. I've been a lawyer for the last 10 years.
