Learn Spanish Level IV contains 10 lessons. Once you have completed this level you should be able to have a conversation with a native Spanish speaker. Each lesson contains between 500 and 1000 sentences. Each Spanish lesson takes between 45 minutes to an hour to go through. Level IV will take between 7 and 10 hours to complete. Level IV is a continuation of Level I and II. It is not necessary to have done Spanish Level I, II or III if you have a strong foundation of Spanish vocabulary and grammar. However, Level I is recommended because it sets up the foundation for future vocabulary and pronunciation drills that are used throughout future levels.
