CBSE 12th

It is very difficult because the criteria is of above 70 percent.

You can pursue ITI in any field i.e. mechanic, fitter, welder, etc. But I think you should opt for the Diploma programme because you have already completed your 12th and also, you are eligible for lateral entry programs.

Any of MNC companies are not going to offer you a job on your 12th basis. For that, you need to complete your Bachelors degree in any stream with a good college background. You are going to apply for companies and if you have been selected in any of the MNCs, then you can take a job in them. Mostly, MNCs prefer Masters degree.

The admission process is based on their own merit list. If you have been selected in merit list then you can take admission for SK Somaiya.

If you want to do B.Sc. When you need to take admission for 11th and 12th Science, then only you can take admission for B.Sc. in IT or computer science, but if you are not a Science student, then you can take admission for BCA. Also through BC, you can also study IT and Computer Science.

Hey,
Since you are interested in doing computer studies, after 12th, you should do BCA and after completing your BCA, you can do MCA.

In that case, choose any subject from PCM or engineering or Hindi and do B.Sc Hons from DU, if possible. And, then you can become a teacher.

You can do D.El.Ed, not B.El.Ed. For B.El.Ed the eligibility criteria is graduation but for D.El.Ed in education the eligibility criteria is 12th.

No, there is no chance of getting selected for Karnavaty. Please try for another college and work hard.
All the best.

No, you can't do B.Tech in biotech unless you had PCM or have studied maths as a core subject.
