The Spanish Engine is not a grammar textbook. It is a personal practice workbook where you build your own Spanish using your real life, your memories, and your stories as content.
Instead of copying example sentences, you write your own. That is why it works, grammar sticks when it is attached to something real.
The file has 27 tabs. Each one targets a specific structure. You do not need to complete them in order or all at once, one tab per session is enough.
