slightly confused 2010, difference, remember, comparing

dmrktrading

might sound repeated question so sorry about it.

I finished Equity in december using my 2010 stalla book. Right now I am comparing the old and new Equity books and I really don't see any difference.

On the other hand, would it worth to read equity all over again or should I focus on practicing questions at the moment? My memorisation skills are not great so in any case I dont think I remember much from the theoretical areas.

Advice?
