Identify the subjects required for the course or college
Note the marks obtained in each required subject
Note the maximum marks for each subject
Use the required cut-off formula
For Engineering: Maths + Physics/2 + Chemistry/2
For Engineering with 200-mark subjects: Maths/2 + Physics/4 + Chemistry/4
For Medical: Biology/2 + Physics/4 + Chemistry/4
For Arts/Commerce/General courses: Total marks obtained ÷ Maximum marks × 100
Add the calculated subject scores
The final value is your 12th cut-off mark
