BDS

NEET is the only gateway for admission in MBBS and BDS courses throughout India. There's no other option.

Actaully, it varies from college to college as what is your eligibility, what bands you are having an all that all matters the most.

No you do not have any scope, because if you did not qualify for the NEET, you can not able to get admission in MBBS/bds.

It is valid. But I would suggest you to do a Masters programme in Europe before you start practice. If you are in a hurry to practice, I would suggest meeting an immigration consultant.

If they don't provide you campus placement then you will have to give interviews, etc. In companies, you want to get a job in.

Both the fields are different and why are you looking for these streams? Go for Masters in your own field.

Diploma in Engineering and BDS together practically it will very difficult. Both require full time concentrate and effort to justice to studies. These fields are not correlated, therefore, it is recommended that you may avoidg both Diploma in Engineering & BDS simultaneously.

The eligibility for B.Ed course is graduation with 50%+ so you can apply for the same.
