Hello, Piyali. I hope you have performed well in JEE Mains and I wish you all the best for your future. You mentioned you belong to SC category and you are interested to get admission in CSE at IIEST, Shibpur. IIEST, Shibpur offers B.Tech in Computer Science and Technology a nd as per JoSAA counselling , the opening rank for admission in 2020 (females only) for SC - Home State was 459 while the closing rank (females only) for the same was 2417.

However, as per Central Seat Allocation Board (CSAB) counselling ,  the opening rank for admission in 2020 (females only) for SC - Home State was 20878 while that of closing rank was 87176. So, I guess you have noticed the huge variation in Cut-offs as far the counselling organizations and procedures are concerned.

I hope all this information will help you to clear your doubts. I think it will be better to answer in terms of ranks instead of percentiles as the admission procedures generally take rankings into account, rather than considering percentiles.
