Hi

It is difficult to make prediction as cut off keeps changing every year  depending upon various factors like

------------) number of students that appeared in the neet exam,

------------) kind of marks obtained by them ,

------------)  toughness level of the neet examination

------------)  number of seats available

------------) the category you are from etc

Anyway,

when we go through previous year trends

>>>>>> With  456 marks,

You have low chances for mbbs in government colleges

You can check previous year Tamilnadu neet cut off at:-
