B.Tech

Hi,
No you can't consider it as a graduation because diploma after 10th class is good but after 12th it is of no use because you've already wasted 2 years after 10th. You should apply for B.Tech.

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.

If you want to become a scientist at ISRO, you should appear for the ISRO qualifying exam rather than appear for GATE.
The eligibility:
BE/B.Tech or equivalent qualification in first class with an aggregate minimum of 65% marks or CGPA 6.84/10 (average of all semesters for which results are available)

MBA admissions are based on the open test score that you get in CAT. The admissions are based on merit based and on your percentile score that you achieve. In order to seek admission in MBA, one needs to have scored minimum 50% marks at the graduation level.

It's a decent college with average placements but to know the exact scenario for faculty and placements get in touch with the current students through social media or in person.

Your question is very general, please be little specific for better assistance and name few colleges. Fee structure will vary from private to government colleges.

I think you can pursue B.Tech from reputed colleges in India and then you shall go for Masters course in Germany. If you pursue B.Tech from NIT or IIIT with high CGPA like 9.5 then it would be beneficial to get placed in MNC companies.

Hello,
Sharda University and Galgotias University are good option for you if you want private college in Delhi for B.Tech.
