Computers & IT (Non-Engg)

But according to me, if you have the knowledge, you can become a Salesforce architect without any work experience. You can gain your knowledge from online, read informative articles, use forum and community websites, watch the video, use online tutorials and much more.
You should do the course from any well-respected training center such as - Koenig Solutions, Udemy and much more.

In majority of Universities Maths in 10+2 stage is mandatory requirement to seek admission in MCA. You can seek admission in few Universities such as IGNOU, Symbosis University etc.

I can see that you are not ready for Masters abroad as of now. You must try to work for a couple of years at a good form where you will gain relevant work experience and develop your personality and skills. Then after if you wish, you can go for an MBA.

Since you have cleared your Bachelors in engineering it would provide the right basis to build your career in oracle technologies. It would require a lot of effort but if you keep trying, you should be able to do so.

I would recommend you to pursue MCA through correspondence and start working or even start as an intern after BCA because if you start working after BCA, 3 years work ex as compared to MCA will be more beneficial.
