You could try using the version used in the course (2.66)….Once you get very comfortable with 2.83 or whatever version you normally use, then you will be able to use the principles taught and use those techniques in a newer version. Even then, you might sometimes run into things that are completely different, or even gone, so you’d have to use a different ‘tool’, but then the Forum will surely be able to help.
The other way, is to follow so many 2.8+ tutorials/courses, until you are really comfortable and are able to follow older version videos without problems (apart from the occasional extreme change as mentioned before).
But maybe a less experienced user can give some other tips and tell how she/he does this….
