Which method are you using?
most of the time I used the QBank for L1 - I used the equal-weighting method, all (advanced, intermediate and advanced) qs, include questions previously wrong. I used to set myself 60 question sets every couple of days, on items covered up until that time, and solve them through. It also helped in the initial few sessions when I would take a complete printout of qs with answers – which helped review the wrong questions a couple of days before the exam. CP
