Hello Sanjana,
UCMS has not released the cut-off for 2019 yet, however we can get a rough idea from previous year's cut-off as the cut-off varies only slightly every year.
In 2018, following was the cut-off ranks for All India Quota seats-

• UR- 183 rank- 645 marks
• OBC- 402 rank- 630 marks
• SC- 4153 Rank- 571 marks
• ST - 13807 Rank- 523 marks

For State Quota-

• UR- 3005 rank with 581 marks
• OBC- 10094 rank - 533 marks
• SC- 35349 rank- 468 marks
• ST- 118870 rank- 353 marks
