I endorse the simple strategy
go to the basic and cover as well as possible the area of content , trying to understand each concept and learn as method as possible to resolve a question.
go for valuable material for this area
go for Og in the same, as well
THEN go to next area of study. same process.
each month take a CAT. trying to figure out your progress and revise contents not so clear
at the end take a full test. carefully, examine what went wrong or right (in the same manner).
evaluate if you are ready or not.
I do not know why people have so many confusion about the strategy. if the things go fine ok, otherwise fix your strategy accordingly. is a process almost instinctive
