Hello Balaji, 

Congrats, You have made the right decision. In the current scenario, almost every IT companies are placing BCA graduates for their Software development and Backend jobs. So this will gives a higher chance of job opportunity. Don't be biased on the low fee institutes if you are concerned about the future and career. Because you have to compromise on placements, Faculty, and Infrastructure if you are going with low fees institutes. Otherwise, you can attend the entrance test of the institutes which are providing scholarship based on your performance in the test. I can suggest you one college as an example. Lovely professional University, because my cousin is studying there with a scholarship. So you can refer to this kind of institutes which are providing scholarship based on your mark or performance in the entrance test. 

Hope this information will help you. Please be careful and be wise in choosing right for you. Best wishes. 

Good Luck!
