Download your CDs to your MP3 player
True, CDs are portable, but they can get cumbersome if you need to carry around more than one CD at a time and they clearly require you to have access to a CD player even if you just want to listen as you take a walk or jog. If this is a problem for you, then you should download them to your mp3 player for a more lightweight option.
All things considered, I’d say that these learn French CD courses present a great option to the classroom setting. You can get virtually all the same instruction in less time for less cash up front.
