If you are from Arts background then it wouldn't be difficult for you prepare in less than 1 month.

Toefl consists of 4 sections : Reading, Listening, Speaking and Writing. And one more section which is the experimental section.

Writing in the toefl is not at all difficult if you have practiced argumentative essay writing.

Reading: Skim through the passage once and then try answering the questions so you get an idea of which paragraph the answer might lie in.

All the best!!
