This app provides a suite of English grammar tests to prepare students for the TOEFL exam. Each test consists of questions about grammar and sentence structure.
In each question, there are four underlined words or phrases, exactly one of which contains an error. Your task is to identify it.
After you have answered all questions in a test, you will see your score and the answers for the questions, including the corrections for the wrong words.
There are 27 tests in total. The first 3 tests are included in the free version. The remaining tests are available with in-app purchase of the full version.
