Hello, 

The cut off marks are 77.5 as per previous year's TNEA declarations. For top notch colleges like MIT, Anna University, PSG university of Technology, SSN institute of Technology, Alagappa College of Engineering; the cut offs are almost near to 200 with a range of +/-10 marks. As you scored 110, you'd definitely not be getting into any of the colleges mentioned above. If you are particular about CSE, you would be landing up in below average colleges affiliated to Anna University. 

Hope this helped you 

Thank you and keep asking:)
