Here are 3 of the most valuable reference sites that you'll want to get familiar with as you learn VBA. I recommend bookmarking these on your computer.

1. Microsoft's Help Site: https://docs.microsoft.com/en-us/office/vba/api/overview/excel

2. Stack Overflow: https://stackoverflow.com/questions/tagged/vba
   (A great reference for specific needs or questions. Someone has probably had the same problem before, so you can search the community to find answers)

3. Excel Easy. A Simple Reference for VBA Basics: https://www.excel-easy.com/vba.html

The most important thing you can do is to keep trying, keep learning (watching and re-watching the videos in this course) and keep practicing VBA as much as you can. That's the best way to get better!
