Hello Aspirant.

According to the eligibility criteria this year, you are required to qualify either of the two exams- TANCET 2019 or GATE 2019 to be eligible for TANCET counselling. So, you cannot use GATE 2018 score card to apply for TANCET counselling.

You can visit https://engineering.careers360.com/articles/tanca and https://engineering.careers360.com/articles/tanca-counselling-seat-allotment to get detailed information regarding TANCET counselling.

Hope that helped.
