Grammar Fitness is easy-to-use software that helps students improve their grammar skills and provides teachers with measurable results. The program implements strategies which help students cope with many troublesome points of grammar -- including usage, diction, idioms, grammatical relationships, and punctuation. After an assessment, students advance through the program at their own pace. They are able to track their progress through their progress-to-date and session scores. Students' scores are kept in a management system that allows teachers to view and print reports. Designed for students in U.S. grades 6 through 10 (age 11 and up). The program can be used as well by advanced intermediate ESL and adult students.
