Considering the past processes followed by JBIMS, it can be determined that either a direct written score-based admission or GDPI will be expected.
For the first possibility, calls will be issued based on the scores of the CAT and CET exams, and a group discussion and personal interview (GDPI) will be conducted. In this scenario, your academic record is of significant importance. The eligibility criteria for this process include a minimum of 65% in 10th grade and 60% in 12th grade. Thus, if your academic record is not up to par, there may be challenges, but if you perform well on other parameters, you should still have a chance of being successful.
In the second possibility, you can participate in the centralized admission process, where your academic record does not play a role. The admission will be solely based on the written score obtained in CET/All India tests. The eligibility criteria for this scenario align with the CET exam, which requires a minimum of 50% in graduation. So, you need not worry about your past academic performance and should focus on preparing well for the CET exam to secure a good score.
