Plz help me...an advice for my higher education....?

I did completed 12th with 74% with maths physics and chemistry as main subjects...i have a chance to do engineering but i'm poor in maths so i decided to go for BBA...I applied for integrated BBA+MBA in IIPM...i'm in a confusion that whether MBA is good for me to study along with BBA within 3yrs or shall i study MBA after my BBA...which course has more value BBA+MBA at a time or MBA after BBA...? And also i found that IIPM college is not recognised by AICTE and UGC...Is it true and is it a good college for my higher education...? Plz help me... thank you:-)
