BBA Entrance Exam

You should go for BBA and MBA programme or any management course, which helps you in your future for joining family business or you can start your own business. BBA and MBA are helpful for learning business management so I would suggest you to go for BBA and after that MBA.

MATHS - I would refer R. S Agarwal of Class 11th and 12th. Just stick to basics of the chapter in syllabus. Also, go for quantitative aptitude of R. S Agarwal.
REASONING - verbal and non- verbal aptitude of R. S Agarwal, and also solve CLAT materials for reasoning section.
ENGLISH- Go for Arihant and S. chand materials and also solve Oxford's materials.
G. K and business affairs- read newspapers and magzines G. K today will be preferable and play online quiz on current affairs on quiz today.
Practice as much questions as you can and stick with basics especially in Maths and English and there you go.

No, BBA does not have legal reasoning.

Exams is in 3 parts.
Quantitative:

Reasoning and general intelligence.
Level of exam is approximately as SAT exam, it varies every year with some difficult questions. But, don't worry, generally it's a speed test nothing else. In quantitative section question, there will be more of solving part, so do practice papers and clear your basic maths upto 10th standard.

Hi,
Previous year's papers for the Christ University entrance test are not available publicly. In fact, even after the entrance test, the question papers are collected back too so that the paper cannot be shared. You cannot get the question papers. The only thing you can do is talk to your seniors in CU and find out what was asked in the previous year.

Hi!
There are many books available both offline and online. Some of the books I can refer are the following-
Self Study Guide BBA/BBS/BBM
1. Entrance Examination 2018 With General Knowledge 2019 Arihant
2. Guide for BBA/BBS/BBM 2018 by Arihant Publications
3. BBA/BBS 19 Practice Sets for Entrance Examinations by GK Pub.

The forms will be out in February second week and the entrance will be in June. So you should start preparing now. The entrance will not be that much difficult. Questions are generally basic.
You can divide the syllabus accordingly and just devote your regular time. Cover topics which arr known to you and excel in that. You can crack the entrance.
All the best!
