Speaking and Writing Strategies for the TOEFL iBTIncrease your TOEFL iBT score by increasing your speaking and writing scores. How? By using the strategy called argument mapping. Why argument mapping? Because the TOEFL iBT speaking and writing sections are all argument based tasks.

With argument mapping, you will be able to do just that.
