Need to learn SAP BPC

Hello SAP Gurus,

I am working on SAP BW from last 5 years . I am assigned to a SAP  BPC project  which  will get started in 1 month of time  .   I have few doubts which are listed below

1.Are there any Pre requisites to learn SAP BPC ? Do we need to have core finance knowledge to work on this ?

2. What are the best methods to learn  SAP BPC on my own ? ( Since i have less time i cannot take training out side .  I am interested in self learning )

3. If i would get an  opportunity to work on SAP BPC / SAP HANA  , which module i can choose ?

Please  give your valuable suggestions on this .

Thanks,

Teja
