I received this comment:

We ordered the Visual Latin program and love it. I would appreciate a phone call or phone number to contact someone and ask about recommend methods for memorizing the case endings.

Here is my reply:

I wish there were an easy answer to this.  When it comes to memorizing all of the endings, I recommend repetition.  Use them over and over again and eventually you get used to them.

I have started a free series on YouTube on this topic.  

You will find the videos here: https://dwanethomas.com/memorize-latin/

Let me know if you need more help!
