In the Easy Grammar Ultimate course, students learn high school English grammar in a highly efficient program which features 180 daily teaching lessons, lasting 10 minutes each. It teaches important skills in a very direct and logical progression. Students first learn the difference between an independent clause and a dependent clause. Using the understanding of this concept, students learn construction of fragments, sentences, and run-on and the structure of compound and complex sentences. However, mastery of dependent and independent clauses first is vital to the ensuing concepts. Student workbook and Teachers Key are included in the Ultimate Series.
