Delta's Key to the Next Generation TOEFL Test: Advanced Skill Practice Book (repost)

Delta's Key to the Next Generation TOEFL Test: Advanced Skill Practice for the iBT is a new series of high-quality practice materials for students preparing to take the Test of English as a Foreign Language Internet-based Test (TOEFL iBT).

This test, introduced in September 2005, replaces the earlier computer-based test known as the TOEFL CBT. The iBT assesses proficiency in the four language skills of reading, listening, speaking, and writing. The most important changes in the test are:
Speaking skills are evaluated.
Some tasks involve integrated skills, such as reading/listening/writing.
Knowledge of grammar is not tested separately but is assessed indirectly throughout the test.
