VC (Mulitple Round) / Two Period Binomial Option Pricing single, everything, multiple, periods, pretty

Have a pretty solid handle on Single Round VC and One Period Binomial, would you put extra time into working Multiple for VC and Two Period for Options?

Or does anyone have a good tip for keeping everything straight when extending out multiple periods for these?

I would hope that they would just ask single period on the test.
