Hi,

In Andhra University, the department of Electrical and Electronics engineering consist of 9 seats. If you want to top the exam then you need to score at least 160 or above. If your score is about 160 or more then that then you will get a rank >50. 

Though the allotment to seat and ranks varies according to the score and caste, the rough idea is that your rank should be 1500 or less then this.
