I believe that a regular practice of set of questions works. Somebody suggests me it in my topic on "Advices" and i observe 2 major differences : I trust more in my preparation and i obtain result (well need to be confirmed on long range).
What i do daily:
> I practice 15 SC - 15 CR and 2 RC.
> I spend time and energy to well understand my mistakes, to create a ErrorLog files, and to write flash cards
> I finish by 30 Q : alterning 1 day DS and 1 day PS
I keep my weekends for Tests
I observe as well that it's not fitted for me to stop the practice on a section and to concentrate on a specific area : I need to maitain what i learned by a constant practice
By the way, I'm not the most expert here on preparation :D... Wait & See other answers.
(During the waiting time, I suggest u to compulse all topics of this fantastic website : I'm sure that u will find a lot of answers
