VB is Visual Basic. It is a stand-alone application for designing your own programs.

VBA is Visual Basic for Applications. It is a version of the Visual Basic language that is used for enhancing Microsoft Office applications.

My VB courses cover JUST Visual Basic programming. While they will provide you with a good foundation of VB for use with other VB-related projects, you will not benefit from them unless you actually have the Visual Basic development program.

I do cover VBA for Microsoft Access in my Access classes, starting with Access 301.
