Excellent resource for individualized, self-paced first and second year programs. Teachers can also use it in class for reviewing before a test.
The website offers a wealth of progressive exercises in the form of short quizzes with feedback on correct and wrong answers. Navigation is very easy from one level to another. Most exercises are geared toward communication and based on various topics or situations such as writing postcards, understanding a letter, buying a newspaper, etc. All grammatical exercises (conjugation, pronouns, word order, etc) are contextualized and require attention to slight changes in the content of the sentences.
