Title: arm floaties not a life raft
Review: The guide is helpful for basic grammer needs. Essentially, it will help you stay afloat if you have the periodic question or need a refresher, but it wont save you if you are completely lost in terms of grammer rules. It doesn't offer enough examples to fully explain the grammar rules, and sometimes is ambiguious (i.e usually you do "x", but it is also okay to "y" or "z").
