Colleges in Gujarat

As per your past academic record, your probable standing are as follows:
1. For class 10th, your score is 2 out of 10
2. For class 12th, your score is 2 out of 10
3. For Bachelor's degree (if Science) your score is 10 out of 10
So, Application rating (AR)= 2+2+10=14 out of 30
The shortlisting of candidates or call from IIMA for AWT and PI will be done on the basis of your composite score= 0.3 (Normalised AR score) + 0.7 (Normalised overall score in CAT-2018). The upper limit of candidates those will be shortlisted in your category is 57. The Normalized AR score of an applicant is equal to their AR score divided by average of the top 50 AR scores from the applicant's pool, (the applicants pool in this case being defined as the group of candidates who appear for CAT-2018 and apply to IIMA.)
So, in my opinion your composite score is quite good because of performance in graduation and CAT Hence you have a good chance of IIMA call. Good Luck.
