Ive tested both, and the 5 a week seemed to be seriously counter productive for me. Now I am on a LR question (chapter in LR bible) type a day, example: 60 assumption questions in a row.... and a timed LG section every day. Every day a new LR type goes bye a new flash card is done up with all the important notes about that type and I review those daily. I have never had a problem with time however so this is more productive for me, for some odd reason I always end at 35 minutes heh, So I do one timed preptest a week on Friday. This will be increased only in the last week which will be 5 section preps timed, 4 times a week.
