Hello Arun. If by JNU you mean Jawaharlal Nehru University then unfortunately they do not provide the course of BCA.

But Jaipur National University provides BCA course and is also one of the top colleges for BCA in Rajasthan. You can obviously apply for JNU provided that you have passed your Class 12th exams with a minimum percentage of 48%.

Hope this clarifies your doubt. For more queries comment down below.
