hi,

see st joseph college of engineering is affiliated by anna university. admission is based on tnea counselling process where students get colleges as per their 12th score. however every year cutoff score changes ,which depends on certain factors like number of applicants, questions difficulty level, seat matrix , category, choice of stream etc. however  I have mentioned about the closing rank of stream below,

B.E. in Electronics and Instrumentation Engineering- 95114

B.Tech. in Chemical Engineering- 19283

B.E. in Mechanical Engineering- 20510

B.E. in Electronics and Communication Engineering- 10689
