I have done 12th but due to some reasons I have not been able to take admission this year. Can I take admission in 2019 for BCA?

Hey, Yes, you can easily take the admission, you need to get the affidavit for the gap years and clear the entrance exam for the course. An affidavit is important for the gap year as the reason for the gap is mentioned in it and universities demand it too.

Yes, you can take admission but if you have any reason for that gap and also if you clear the college entrance test then after that you will be able to join BCA after 1 year.

Yes, you can take admission into BCA after a year's gap. You'll have to provide a reason for that period, you can show a certificate of a course which you could be pursuing. Many students take a year gap and they get admission very easily. Just make sure that you provide all the necessary documents

Yes, you can take admission, but you need to clear the entrance exam that universities conduct and on the basis of that, you will get admission and for registration, you can apply online on the official websites of the universities of your choice. Good luck.
