Hello,

The cutoff marks for TS ICET 2020 will be released later on. As per the previous year the cutoff was 25% of 200 that is 50 marks  and is expected to be the same this year too. You mentioned your marks to be 70 in bc-b category which means you do qualify but it is difficult to give assurance of getting a seat in JNTU college.

Although according to the previous year the cutoff for 2019 for first round was 19883. You could use this link for more information- https://bschool.careers360.com/articles/ts-icet#TS-ICET-Cutoff-2020

Hope it helps.

Good luck.
