The NFB/NLS UEB course is intended to be a replacement for the literary course manual. It teaches braille from the standpoint that you don’t already know braille. It’s never a bad idea to reinforce what you know about braille by going through a course that starts at the very beginning (that is also what the Australian on-line course does). I do not know, at this point, if NFB/NLS is working on a course for those who already know EBAE braille that will help them switch over to UEB. I can check and will let you know if I find out something more.
