Polytechnic

BCA is much better as compared to B.Sc. Because, B.Sc is a general course whereas BCA is a technical course. Getting a job after BCA is relatively easy as compared to B.Sc. As you are not able to pursue B.Tech, then you'll have to work much harder on developing skills and knowledge while pursuing BCA in order to achieve a good career with nice salary package. If you want to learn programming languages which you will be studying in your BCA course then you can check out this app which is specially designed and developed for BCA students. 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. https://play.google.com/store/apps/details?id=technark.bca_courprogramming.

Hello Muhammad,
Your query is a little cryptic one. If you had written in details, it would have been better answered then. Of course, I will still try to answer, as the way I have understood your query. Perhaps what you are saying is that, after completing your 3 years of study in a Polytechnic College doing Diploma in mechanical engineering you are no more interested in further studies, but is looking for jobs. Right? If this is so it is okay. There are plenty of Jobs available for Diploma holders in mechanical engineering. Indian industry is already showing signs of revival and is hiring in good numbers. I would advise you to register yourself in one of the job portals giving details of your qualification and expectations. I hope with this you will soon get call up for your job. Best wishes to you.
