Provides students with interactive grammar exercises that help students master difficult points in English grammar. After an assessment, students advance through the program at their own pace. They receive frequent explanations for their answers, whether the response is right or wrong. Teachers and students are able to track improvement through our record management system. The questions, answers and explanations of the programs can be spoken aloud. Designed for students in grades 6 through 10 (ages 11 and up), the program can also be used by English language learners and adult students.
