I am currently doing my B.Sc CS through distance education can i apply for TANCET?

Hello student you didn't mention you're talking about which course I request you to please help me with it so that I can provide you exact information. If you're talking about MCA through TANCET then yes you can apply for it as eligibility criteria says that students should hold a Bachelor degree of minimum 3year duration in BSC/BCA (computer science /information technology) with Mathematics in 10+2.

Feel free to comment if you have any doubt
Good luck
