Ben’s right. I like review. When it comes to languages, you almost can’t get enough.
You could easily break it down this way:
8th Grade: Visual Latin 1
9th Grade: Visual Latin 2 and Lingua Latina.
10th Grade: Continue on with Lingua Latina.
Lingua Latina more than satisfies the requirements for high school Latin.
If you do this, and find you need help with Lingua Latina, I have taught the book for years on my site: http://www.dwanethomas.com. Some people find they need help in the latter chapters. It’s a tough book. Well worth it. But, tough.
Let me know if you need more help.
Hope you are having a great night!
