You have a great chance of getting seat in IIEST, Let me tell you in detail.88.05 percentile means your score will be around 85-90.And if we compare with last year marks vs rank( I know it won't give us a exact number, but we can assume it approximately.) Your rank would be around 3000-4000and last year in IIEST the opening rank for 1st round was 3718 Means you have a great chance. And also you are from Bengal so your opening rank will be even low Keep in mind don't ask much questions on career 360 Here, sometimes they are giving wrong info, or they say there things by there rank predictor , which doesn't make aense.So have faith, if your rank is more than 5000(which is not possible) then focus for advance or state entrance exams
