New to cards of truth

Hi, 

I decided to learn cards of truth and I must say there is lot of videos I need to sit through for the beginner.

I normally listen to the videos as I work on my financial audit and I was interested in 

birth card compatibility  but I realise I can't skip steps. 

I have Kala software but do I need a cards of truth software now in order to learn this course  or can I wait to see if I last in the course first?
