Hey, 

As per recent cut offs of Anna University, the opening rank of Industrial engineering is 171 marks. You might be placed in Industrial Engineering if you attend all the phases of counselling. The opening rank of Civil engineering and Manufacturing engineering is 179 and 176 marks respectively. There might be a fluctuation in the cut offs and if you are fortunate enough and the cut offs go down, you'd be securing a seat. 

Thank you:)
