As you didn't mentioned any specific category I am assuming that you are a general category student. The cutoff changes every year as they depends upon various factors like number of students appearing for the exam ,availability of the seats. Like in year 2017 the closing marks for general category were 313 whereas in 2018  it was just 151. But you don't have to worry you have a descent marks you'll easily get admission in the college.

You can check previous year cutoffs of BLAT by going through the link given below.
