In general Rocket Spanish does a decent job teaching the language. However, it fails to explain the rules and reasoning for the language's grammar, especially when a phrase or sentence contains multiple verbs. Also, so far (into lesson 1 of section 2) there has been no explanation of the Spanish use of the word "lo". I am struggling with the contextual grammar, and I don't think it's really any fault of my own.

Response from Rocket Languages: Hi Martin - Have you had a chance to check out the Language & Culture lessons? These lessons are all about grammar and take you through how the language works step by step. You can find an explanation on what happens when verbs are used together in a sentence in Lesson 2.8 under the heading "Using Two Verbs in a Row" and an explanation on LO and how it works in Lesson 5.6 under the heading "The Thing About LO"
