i need help figuring the right logical argument of this type..

col. A are grades then col b is where i put the logical argument

95 to 100=A how can a make this in formula range 95 to 100 in col. B letter "A" should appear...

all i know is if command like =if(A1=95,"A","None") this formula only applicable to one value and not range between 95-100.. how can i make it...
