Family Business Preparation

Well, every university or college has different eligibility criteria for the MBA entrance exam I do not have any idea about any other university but I can guide you about the LPUMBA entrance exam.
Eligibility Criteria (Qualifying Exam):
Pass with 55% aggregate marks in Bachelors degree (any discipline) or equivalent, subject to qualifying LPUNEST or CAT or MAT or XAT or NMAT or CMAT^ and Interview.
If you do not have any of the national tests with you then you can give the LPUNEST entrance exam for the MBA
The exam is generally held in two parts, first one is the online exam based on the course you are taking admission is, and the second part is the interview, aggregate marks of both then decide your criteria for getting a scholarship.
If you are not satisfied with your scores, you get a chance to reappear for the exam and improve your scores.
However, the exam to be honest is neither too tough nor too easy, you need minimum preparation, to get good scores and hence the scholarship amount.
LPUNEST exam syllabus is based on the knowledge of your last qualification. The topics you have covered or have already studied in your last qualification will be included. The syllabus varies from programme to programme. For the details, you may visit the website.
Under the information tab, you will also find the previous year's question paper and the paper pattern which might be of some help to you.
Good Luck!
