Grrr, Gann stuff is quite expensive to get. Start of on Michael Jenkins "Chart reading for professional traders" you have to get both of this books. This gives you a good overview and some deep insight on Geometry, they are great books.
Then go to a more recent persone Bradely Cowan and get his home study kit then move on to Ferrera stuff from www.sacredscience.com.
After that you will need to plow into astrology which is really hard and once you done that all should be good.
Sounds a lot now, but do it in the order above and you will be addicted to it in no time.
