TS EAMCET 2019 is scheduled for May 3rd to 9th, 2019 in CBT mode.the results will be declared by the end of the may month on the official website. As the exam was not taken till now, its difficult to make any statement regarding the cutoffs. It is possible that paper will be easy and cutoff marks will go high or the vice versa. 

I can give you the idea of marks by the last year cut off for the JNTU, Hyderabad. For the SC category the last year cut-off was  125 to 98 from the total of 160 marks.

Work hard for the exam and do your best.
