- Using estar for occupations is wrong because jobs normally use ser, as in Mi madre es profesora.
- Using ser for location is wrong because where someone or something is located normally uses estar, as in El cuaderno está en la mesa.
- Forgetting accent marks in está and estás is wrong because the accents distinguish forms of estar from other words and show correct pronunciation.
