Mechanical Engineering

Yes, you can opt for B.Tech after completing Diploma. There are some universities which allows you to do that.

Don't worry as every body face hard times in their study period, so keep calm and concentrate in your 7th semester. After that, when you are in 8th semester, you are eligible to clear your backlogs, so first complete your 7th semester, then start your backlog study with 8th semester and appear for the same.
All the best.

Hi Neeraj,
For MBA abroad you must first gain a few years of work experience, if you want to get into a good university. 2 years is minimum. Additionally you must take GMAT or GRE and TOEFL or IELTS. You can also check MS Management courses which do not require work experience. Entry requirements also vary with universities and countries hence go through university websites and decide where you want to apply.

You may have difficulty in getting admission in MS abroad because of your acedmic performance in graduation degree.

You have two best option, but Australia and New Zealand, both are very expensive country. But, it is worth for you. For low tuition fees, you can choose Poland as they accept low CGPA as well as low cost of study and living, but job prospect is not good. You have to search jobs in Germany after completing your MS from Poland.

Both aeronautical and mechanical engineering are excellent branches of engineering. Mechanical is an ever green branch for last 50 years with wide scope in all type of manufacturing & services industries and will continue to remain same in next 50 years. Aeronautical engineering is niche branch of engineering with relatively lesser scope in comparison to Mechanical engineering. However, Aeronautical engineering has more opportunities for R&D, innovation and scope to work on cutting edge technologies. You may chose of the any based on your interests to excel in your engineering career.

1. Chief engineer.
2. Assistant engineer.
3. Designing engineer.
4. Robots engineer.

I am not quite sure, but I think most graduate programs in Germany are offered in English. And, if the medium is English, you need not require test for German.
