Hello Srtivani.

According to the previous years rank vs mark metrics, for 50 marks you would get a rank close to 32K-35K. Since you got 43 marks, your rank can be around 38K-40K. It evan depends on your 11 and 12 class percentile. More the percentile you have in 12th, the more are the chnaces of getting less rank in EAMCET.
