I got 42 marks in eamcet then what is my rank
For EAMCET, ranking would be based on several variables such as students' overall performance, normalization, and category. But looking at general trends from past years, a score of around 42 marks should give you a ranking of about 30,000 to 50,000, depending upon how difficult the paper was and the number of candidates.
For a more accurate rank estimate, you can check the official EAMCET rank predictor tool once the results are out.
