Indeed you can do BCA following 4 years of the hole.

The gap in the scholastics isn't great. On the off chance that you have a genuine justification for the gap then it isn't destructive in any case it shows your imprudence approach to your vocation. So plan with the coherent justification behind your gap year then everything is good to go.

Most Colleges give affirmation to competitors who have under 24 years. So, you will certainly get a confirmation for the BCA course.

A few institutes of BCA are referenced:

SRM Institute of Science and Technology - SRM University, Chennai

Christ University (CU), Bangalore

Organization of Management Studies (IMS), Noida

Division of Computer Application, Kurukshetra University, Kurukshetra

Birla Institute of Technology [BIT Mesra], Ranchi

Loyola College, Chennai

Hope this helps. All the best!
