Hello Vikram,

I would like to tell you that every year a large number of students appear for TANCET exam, but the number of registrations is witnessed to have consistently decreased. 

In 2012, it was about  1,10,000 registrations but it has fallen to around 20,000 students in 2018.

I would suggest you visit the careers360's link given below which has detailed info of the TANCET MCA 

The link for the same is:https://www.careers360.com/exams/tancet

Hope this helps and all the very best!
