comparing of speaking courses and skype

i started to speak on skype about 4-5 weeks ago and i started to join speaking courses 2 weeks ago...
i noticed that i improved my speaking skill by using skype...But if i didnt use skype before speaking course , in my opinion i wouldnt speak with my teacher in my course for 2-3 weeks...but now i m speaking with my teacher easily ...and maybe i m best student in my course...
so if you improve your speaking u should use skype ...
you wont regret about it....
