Need guidance for IBA Karachi prep

[ahmed123004]

Any student here from IBA Karachi, I've applied for ACF on Sat score basis, my score was 1310 (650Eng/660math). I need some guidance on how to prepare for interview and I haven't studied accounting or economics before, should I study these two before hand ? And anything else I should look into before agreeing to study in iba karachi.
P.S I'm from ISB..
