Hello Nandhini,
I am going to assume that you are asking about TNEA counselling. Even though you feel like you have your cutoff marks are not good enough, don't worry. You will get into a good college if you want.
Go to this link -> *Click here*
Just type in your cutoff marks, desired branch and category and just look at the number of colleges that you get. So, do not be discouraged dear, Self- doubt and low confidence is a normal part of any persons life, especially during an important point in your life. If you cannot see the college or course that you like (leave Anna University ) then only try to go for management seats.
Also, the above cutoff predictor is for last year. The cutoff marks may vary this year.

hello s. nandhini,
