Is finishing all CFAI practice questions good enough to pass Level 1?

I bought a set of Schweser notes but found it quite time-consuming to go through all the books. Could I score 75%+ if I just master all the 2700 practice questions provided by CFAI?

yes, just reverse engineer and understand why. A lot of the questions are conceptual and will definitely reinforce previous education in finance/econ/accounting at the undergrad level
