Polytechnic

If you want to do engineering, then better ho for Polytechnic and get some practical knowledge rather than doing 11 and 12 Science and sitting in class for mostly theoretical knowledge.
Good luck.

Well, at least, you know that you font want to do Polytechnic, Polytechnic is a good course but if you font want to pursue it then sure you should go for commerce as your interests say.

Netaji Subhas Open University offers Bachelor's degree programme (BDP) in the following areas:
1. History (EHI)
2. Political Science (EPS)
3. Sociology (ESO)
4. Public Administration (EPA)
5. Education (EED)
The eligibility criteria for above programs is passed 10+2 examination or equivalent (Arts or science only) with 45% marks. So, if you have completed class 12th in arts or science then you are eligible. Further, you will not get admission in the above courses on the basis of Polytechnic.

AMU doesn't offer lateral entry for B.Tech course. So try for some different private college. All the best for your bright future my dear friend!
Work hard to get success!
Thank you!

Yes, you can, but for that, you have to pay a heavy fee that the college will charge.

Yes, you can get admission in Government Polytechnic College, Pune in Diploma in mechanical engineering course under institutional quota only. For more details regarding admission and institutional quota directly contact the concerned college. The eligibility criteria for this course is SSC/10th with science & maths with 35% of aggregate marks.

I first appreciate your thought of joining Railways, and I want to clear you something. If you are really wishing for posts like ALP, Je( your Polytechnic Diploma is eligible, but I want to make sure that you have done your polytechnic Diploma in regular basis, and it is a valid undergraduate program approved by AICTE.)In that case, you are eligible to appear for an exam in railways. So, you could apply for that post easily, when you can compete.

You can't pursue, because you are a government employee, and then age may differ. But, you got good percentage. If you want to pursue regular means, you should leave government job and you can go attend the regular B.Tech class.
