Sorry about my english first, i speak chinese.

I study the PMBOK 5 and HeadFirst 2nd (for PMBok4, but seem still promising) in parallel.

almost 1.5 month, i studying the Risk management in progress.

But i feel confuse because i understand the meaning on PMBOK and headfirst,

i understand and memorize the calculation (EV,PV,CPI or FS,LS) etc;

i understand the diagram, and i google much to find explaination.

I read PMBOK as a novel and clip the summary as my study notes.

But i feel confuse...
