No, SoloLearn doesn't offer any lessons on Visual Basic. If you'd like to suggest it, there's a Feedback option in the main menu. Tap the … in the top-right.
By the way, this app provides code examples for VB 6.0, and tutorials, code examples, and an online compiler for VB.NET: https://play.google.com/store/apps/details?id=com.freeit.java
No at all: no course about it, and no support in playground (VBScript was only supported in Microsoft Internet Explorer, and seems to no more be supported in Edge ^^)
