Spanish Level II contains 15 lessons. Each lesson contains between 500 and 1000 sentences. Each Spanish lesson takes between 45 minutes to an hour to go through. Level I will take between 11 and 15 hours to complete. Learn Spanish Level II is a direct continuation of Level I. However, Spanish Level II introduces more concepts and new vocabulary, in addition to pronunciation drills and more advanced grammar lessons. It is not necessary to have done Spanish Level I if you have a good foundation of Spanish, but it is recommended because Level I sets up the foundation for future vocabulary and pronunciation drills that are used throughout future levels.
