The OP “ilove fca” actually loves cfa!! Not because of any reason other than he/she merely "really like the designation" about which he/she learnt in a finacial magazine while entering the details of the magazine in the store-register and glancing through it. I, may be some others on AF too, thought it is a post from “ilove cfa” not …not 'i love fca’!
Since you don’t have the pressure from work to pass the exam (i assume it’s not a requirement as a “store officer”), the best approach is to study diligently and learn the knowledge instead of trying to find “tactics” to pass the exam (if they even exist).
