Hello Raghuvamsi,
You have obtained reasonably good ranking in Andhra Pradesh EAMCET. However almost every student give CSE as the first choice. In view of this if a student desires to get admission in this branch then he need to be in top percentile bracket. I am afraid you are not in this bracket. Hence in the normal course of time it will be tough for you to get admission in this branch. However if you have set your eyes only on this branch then perhaps the course open to you is to seek admission in deemed to be universities or management quota of the private engineering colleges. Best wishes to you.
