Hey ,

St.Josheph's college of engineering declares cutoffs on. the basis of ranks only so i can provide you that only..But still if we consider marks vs ranks,  one should have a score above 160 to get a seat there and the cutoff varies with year and branch.You can check the previous year cutoffs by going through the following link : https://engineering.careers360.com/colleges/st-josephs-college-of-engineering-chennai/cutoff

Hope it helps!
