CBSE 12th

Hello Subabratha,
As per your query and if you're interested to employ in medical/paramedical-relevant field definitely Medical Lab Technology, Anesthesia Technology and Radiology are the best courses which make you employable or provide opportunities to work in hospitals and lab firms. Else, Sanitary inspector is best choice for government job.
All the best for your future.

The minimum score required for HM course is 50% and below 50%, you can go through any private institute.

It is very difficult because the criteria is of above 70 percent.

You can pursue ITI in any field i.e. mechanic, fitter, welder, etc. But I think you should opt for the Diploma programme because you have already completed your 12th and also, you are eligible for lateral entry programs.

Any of MNC companies are not going to offer you a job on your 12th basis. For that, you need to complete your Bachelors degree in any stream with a good college background. You are going to apply for companies and if you have been selected in any of the MNCs, then you can take a job in them. Mostly, MNCs prefer Masters degree.
