Just received it in the mail and started working at it, I think it will be life changing/make life possible. 

BUT I have to go back to grad school soon and I’m scared to go back without having finished it, but it’s a lot. So...

QUESTION: Do you have to do beginning and advanced for each skill before moving on to the next (ie in chapter order), or can you do just the beginning ones first and then come back and do the advanced ones later??
 
Thank you!
