Hi Lina,

Dedicated means you have given all your attention and you would have to use it with the preposition to as in: She has dedicated her life to working for the poor of the world. Occupied in the test means keeping your mind busy with lots of things.

Hi Alan,
I saw in dictionary and found down that 'occupied' has meaning 'full of people or to be in use'. Meanwhile,"to be occupied in doing something/with something" have meaning "to be busy or to relate to sth/smb". Thanks.
