CBSE 12th

BCA is a course where programming languages will be taught to you from the ground base, so you don't need to worry about learning those. If you want to learn something then make sure to keep on revising the formulas and concepts of +2s mathematics, as it'll help you a ton in BCA. Or you can even begin learning programming too that will also help you in your course. Begin with C Language, as most of the BCA colleges will teach you the same language. If you can understand the concepts early, you'll be able to code more efficiently and will perform better in exams. If you want to learn programming languages which you will be studying in your BCA course then you can check out this app "BCA - Course Programming" which is specially designed and developed for BCA students and is available on Google Play Store. It has programs and assignments of languages like C, C+ and Java with their outputs. You'll be studying these languages in your 3 years of BCA.

Hello,
Yes, it is difficult to choose any UG course, but if you are really interested in doing your Bachelor's degree, select the one which you are really interested in pursuing your career. This interest shouldn't decline over the years, as you are going to complete each year of your degree. It is always good to have a backup plan for example, there are number of courses related to the Bachelor's degree you choose. If you have chosen computer Science you may learn Java or python in your free time or the holidays you get, so that it becomes an added advantage while you are seeking a job or if there's any placements in the college, it is definitely going to put you in a safer position than other students who are competing along with you.
