I disagree.  I say focus more on text (i used becker).  This is for FAR only, the other sections, i would say focus on the questions and keep doing it multiple times.  I didn't intend to do it like this, just that things outside my control led to my prepratory routine being cut short.  But it turned out that I survived the exam ok. 

The questions i would say prepares you for degree of difficulty in the actual exam questions.  So you know what type of ways they can really mess you up by adding in extra components to throw you off.  I found there wasn't much of that in FAR, and my theory for this is to strike a balance between degree of difficulty vs the wide scope of material covered. 

Like Aesop said, having that day before the exam to relax is really important.
