I am a final year BBA student at Christ University Bangalore.
Christ does not give much value to class 12th results during admissions. However, a candidate must score at least 60% in class 12th and 6 CGPA in class 10th to get admission in Christ for a BBA.
The university offers admissions based on the entrance exam results. The shortlisted candidates are then again tested for writing skills. Those who qualify these two tests have to give a micro presentation and personal interview. During the personal interview candidates are asked general questions related to their choice of degree and their personal information.
Thus, you can surely get admission into Christ University Bangalore for BBA with 75% in class 10th and 78% in class 12th.
