Hello,

Cutoff ranks for B.Sc Geology can vary depending on the university or college you're targeting and whether you’re from a state or central board. In most central universities or reputed state universities like Calcutta University, Delhi University, or Presidency College, the cutoff for non-state board students is usually a combination of marks and merit rank.Typically, students from boards like CBSE or ICSE need to have 85% or more in Class 12 with science stream to be in safe zone . But in colleges with entrance-based admissions (like BHU), a cutoff rank can range from 100 to 400 in their respective entrance tests for general category students.
