Formation électronique en ligne?

Portrait de LennoxConner


I had the electronic bac F2, 15 years ago already. My professional life has steered me in another direction.

Today I have the opportunity to come back to this specific area. 

Could you please advise me on online training which will allow me to refresh my general electronic knowledge?

I will also study in parallel, the COURSE part of the site. 


Thank you
