Hi Wendy,
If you're looking to upskill in Premiere Pro or After Effects, I'd strongly recommend Justin Odisho on YouTube. They are short, easy to follow videos that have a great range from very basic to advanced.

For Lightroom, Peter McKinnon is really good for many of the same reasons, although his tutorial video are a little longer.

This consists of all the material I used this year in my Year 12 General class.
Hope this is useful.
All the best,
Gooch!
