If you scored 70 marks in AP EAMCET, your expected rank would be between 15,000 and 25,000, depending on your category, board marks, and the difficulty level of the exam. For OC category students, the rank might be on the higher side, while reserved category students may get a slightly better rank. This is just an estimate, as actual ranks can change each year. You can check the official rank after results are declared based on your final marks.
