Christ University

You need to check on the university website for any such information. As of my knowledge, there are hardly any 2nd Cut off lists.

For Christ University, you will have to clear CAT or MAT exam and that too with good score. For fee structure, you can visit their website.

GNLU is the best option for this. It has a high rank among the top law colleges.

With this percentage you won't get admission because you have not cleared the mathematics subject which is the main concern for BCA programme admissions.
You can check B.Sc-IT programmes in other universities.

For applying in this college you need to visit the university website i.e. www.christuniversity.in there will be a link talking about admission 2017 which will give you a list of all the courses that the university offers. You need to select the course which you are willing to get admission into and then it'll guide you through the entire process of admission and the important dates for it.

BBA in Christ University is ranked number 1 at all India level.
Comparing it to other courses that too of other colleges will not be apt.

There is no need to send your marks sheet to apply in this university. It has an interview procedure.
If at all any of the programs require you to submit your documents, you can send the via post addressing IPM of the university.
