Hello
Whats done in past is done. Do not think that you will be below anyone because of the low scores. Anyways as a rule of thumb these low scores can always be compensated by higher CAT percentiles. There are many colleges which do not give much weigtage to past academics and you have achance to secure higher marks in BBA to improve your chances.
So stop thinking about it and start working hard on academics now and prepare for CAT.
and you will get diversity marks over engineers which will boost your chances.
All the best
