• Qualifying percentage of marks for AP EAMCET 2019 is 25% of the maximum marks considered for ranking.
• However, for SC/ ST candidates, no minimum qualifying mark is prescribed. But their admission will be limited to the extent of seats reserved for such categories.
• Candidates obtaining qualifying marks in AP EAMCET, if after normalization, the marks(s) in any individual subject(s) become negative, then the normalized mark(s) in the respective subject(s) are treated as zero. However, total marks in three subjects are considered as EAMCET marks.
• For SC and ST candidates for whom there is no qualifying cut off if the marks in all the three subjects after normalization go below zero (negative), the total marks are treated as zero and the rank is assigned based on 25% of Intermediate marks weightage.

Thats why maybe you have mistaken for the last year qualifying marks compared with this year. So i must say that you should cross check for it once again as during the result time this kind of incidence happens generally.
