How to prepare for the Mexican naturalization exam
Start with the SRE study guide and its main book, practice by topic, then take one timed practice exam a day in the final week aiming for 9 or 10 correct out of 10 so you have a margin over the 8 you need. Read the explanation even when you are right, because the exam rewords questions, and practice in Spanish since the exam is in Spanish.

| 1. Read the source | Read the SRE study guide and its bibliography; the main book is Nueva historia mínima de México (El Colegio de México) | It is the only official reference the SRE publishes |
| 2. Practice by topic | Work through the ten topics, from pre-Hispanic Mexico to everyday Mexican Spanish | Finds your weak topics early |
| 3. Start with the most reported | Do the most reported questions first | Applicants say they make up most of the exam |
| 4. Final week | One timed practice exam a day; aim for 9 or 10 | You need 8 to pass: leave a margin |
| 5. Review | Read the explanation even when you are right | The exam rewords questions |
