Mechanical Engineering

IIT, Mumbai is the best option.

Attend the college regularly. Prepare your notes, and memorize them. Refer to the books suggested by the college.

Hi Devendra,
Diploma in mechanical is a good choice to make your career in mechanical either design or core mechanics. I don't know what makes you want to take tourism. Both the courses are different in nature and career opportunities.If you want to start your career in tourism, then go for it, but think why you opted for tourism course? Think about the options you have at present in mechanical. Compare both the fields and scope they have. Remember degree is not enough to start your career.
Can I know the reason behind your decision?

You should join vocational courses which are related to your field of interest and education.

Germany is the best country for mechanical engineers, but with your marks, you cannot get admission in Germany, so It is better to opt for Australia or New Zealand.
All the best.

You need to get admission in a university, not college. Check out the link mentioned below:

Hi Mitesh,
SAP requires good understanding about business process and understanding the requirement of a client.
Once you work for 3 years in a particular company, you would be familiar with the business process, and you can start looking for more options later.
You won't get a job after completing SAP course easily. I would also say it's not tough, though. It takes time, many opportunities will be available in future.
Good luck.

All the three are good. What is your budget?
If they offer Ph.D that shows they have tie up with industry.

You should opt for M.Tech in industrial engineering.
