Target percentile

Hi, I’m a General-category female candidate with 100% in Class 10, 98% in Class 12, and a 7.12 CGPA in B.Tech Chemical Engineering from IIT Madras. I’ll have around 1 year of work experience by September, and this will be my first CAT attempt.
I started preparing seriously only last week. Considering my academic profile and work experience, what CAT percentile should I realistically target to have a good chance of getting calls from IIM ABC?
