The cut-off marks of any institute vary every year and you can not rely on the previous year data. It is calculated based on the number of students that appear for the exam. It varies for students from the general category or reserved one. 

If you belong to the general category you might want to work a little harder to make it to the list of students eligible for admission. 

In 2019, there were 34 seats for general category students, and the next year, it got reduced to just 26. As the exam carries 200 marks, so roughly we can estimate that the cut-off might be around 165 for the general category. 

You can utilize the time in preparing precisely and solve some papers too. Revising the topics more and more will get you accustomed to the question pattern.
