Hello Uma.

Well I can assist u in this. See there are two ways to get admissioned in the ANNA University to pursue higher studies like through TANCET or through any entrance exams.

So if u have GATE exam and are qualifying for taking admission in the ANNA University then there is no need to give any extra exam for taking admission as TANCET is for the state quota.

Hope u got ur point. Ask for any other query.

Good luck
