Schweser L1 Refresher set, sufficient, remember, should

chandsingh

As in the subj, should I bother with Schweser L1 Refresher ?
are level 2 notes a build up on level 1 or a standalone set of notes, ie, if do i need to remember 100% of level 1 to do well on level 2, or if i study for level 2 alone, is that sufficient?
Thanks.
