Stalla Passmaster

Any input on to how Stalla Passmaster questions compare to the real CFAI exams? I heard from a few that they do compare simlarly to the real questions… There also has been some press releases on how Stalla has partnered with CFA Institute… wonder any ties from there… I heard alot of input from people that Stalla is superior to Schweser (and also more expensive…)… I guess it pays… to have high quality products? My plans: PASSMASTER ALL CHAPTERS… .already halfway through… and then on to the CFAI SAMPLE and MOCKS… Can anyone else give me input

Quality of Studying over Quantity !!! Id rather passmaster it all and stomp on the theortical concepts before doing the underlying general of sample exams… woot woot 2.5 more weeks!
