The Cambridge Preparation for the TOEFL Test, Fourth Edition, helps students master the language skills they need to succeed on the TOEFL iBT and communicate effectively in an academic setting. The CD-ROM offers seven practice tests in an electronic format that simulates the TOEFL® iBT. All tests can be taken in practice mode, which includes an untimed option, answer key, and other features for extra support, or in Test Mode, which looks and functions just like the actual TOEFL® test.
