resources / technical skills development for freelancers

I am planning to spend time later this year on professional technical skills development, and take myself quite beyond the slimmest basics.

I would like to ask members here for recommendations concerning links to online tutorials or similar, that they have also used and can (highly) recommend.


I am seeking these in the areas of - MS Word, Excel and Access. I am seeking to avoid the relevant Help sections of each of these applications.
I think and hope that devoting 3 months to each of these should do the trick.

I am open to book recommendations; however, I may not be able to purchase them locally.




Thanks.
