Do I already need to know a lot of astrology?
The guide has instructions for how to find positions in charts, and the course has all of the interpretations you need to use. You may benefit from knowing some predictive astrology with the transits and progressions info, but if you don't know that, you can grab the beginner predictive astrology course, Get Started With Predictive Astrology to cover transits, or Make Astrology Predictions to cover progressions).
How long do I have access?
The PDF files are downloadable, so you have access for however long you have them!
What format are the files delivered in?
It's entirely PDF files (so you do need free Adobe Reader or Google Drive to view them; most computers and smart phones already come equipped to view them).
What currency do you use?
US Dollars (comes out to around 20 Euros, 30 Canadian Dollars, and 33 Australian Dollars; you can Google converting to your currency since this fluctuates). And you can pay with a credit card or Paypal.
