Hey anusha!

I can understand your query that you want to know the possible colleges for you with rank 79000 and your category is OC and preferred branch is ECE. But as observed , you have no where mentioned the name of exam . So , kindly mention the name of exam .

But , from my side , i assume the exam to be AP EAMCET. And in this case , you can predict the list of all possible colleges for you by using AP EAMCET college predictor tool:
