Have I translated this correctly
I think you should get good grades.
"Pienso debes sacar buenas notas."
1 Answer
Pienso que deberías sacar buenas notas (you think it´s their duty to get good grades).
Pienso que debes de sacar buenas notas (you think they will probably get good grades).
In both sentences, however, it sounds more natural without Pienso que.
