Hello dear student,

What I would recommend you to prepare for the exam with what's your time is left in your hands for the entrance test of BBA. And if you will not be able to secure good marks after putting in all efforts in limited time and you think you can get admission in a good college if you drop a year and prepare well. only then dropping is a good option otherwise if you will not be able to get a good college even after dropping a year then you will regret wasting year. All the game to prove is never wrong. I hope this was helpful for you

Thank you
