Dear saket Singh. Item provides admissions on the basis of university entrance examination. All the best.

Integrated MBA is BBA+MBA. The advantage here lies in that once you've laid a solid groundwork in you graduation; it becomes much easier to select the specialization of your choice. The five year course gives you a solid grounding in the basics of subjects like HR, Finance, MIS, etc and then hones your skills in a specific area, immensely boosting your job prospects.
Equipped with an MBA, you will have a lot more opportunities in the job market. Since you will have a specialization in a certain field, you will be given preference over someone with a just a Bachelor's degree.

your 12th percentage will not matter from next year in JEE ranking . and it doesn't matter if you have 88 in board all it matter is weather you are ready to be alone for a year or you are ready to dedicate a full year to study and remember it is very difficult I am also a dropper and also I found it very hard to study after December because I was studying the same thing
so all last it is all up to you .

You should start the preparation.
