Diploma

After Diploma in mechanical, you can pursue B tech in mechanical, robotics and automobile engineering.

Sorry Sachin. Getting a certification does not guarantee you a job but makes you eligible. Job is a thing you get on competition and knowledge basis.

Yes, you can do automobile engineering by lateral entry scheme where you will directly get admission in 2nd year.

Yes! You need to clear any national level entrance exam to get selected. Universities like Panjab University, JNU have a international quota. You can apply through that.

Technically, you can do. Please contact the college/ university for further information.

It's better to go with B.Sc. Nautical Science degree as it is of more importance. B.Sc. In Nautical Science is a 3-year undergraduate course which is split into 6 semesters. Each year consists of 2 semesters and contains a thoroughly practical approach to all the concepts of Nautical Technology.
Thanks.

No, going for nautical science after 10th will not help you as for B.Sc in nautical science basic eligibility criteria is to have 10+2 completed. So, even after doing the diploma also you cannot proceed with that.
The best option for you will be PU completion.
Thanks.

Hello Mahesh,
You have taken admission for diploma course in this Institute and for some reason you have left it half way through and now you want to rejoin your course. Is this correct? Normally Institutions do readmit students who had discontinued their studies due to some unavoidable circumstances. It could be financial trouble or even health issues. You need to approach the administrative staff of this Institute and seek their guidance of how to resume from where you have left. I am sure they will guide you correctly and you will be able to restart your held up studies.
Best wishes to you.
