Germany

It is not free Aratrika.
Dentistry programs in these countries take up to 6 years for completion. In Germany, they are not split into Bachelors and Masters degrees. Students must clear the State Examination (Staatsexamen) after course completion. So there is no point looking for MDS courses in Germany unless you want to start afresh. This is the same in case of France too however there are exceptions offering post graduate studies. So, please write to the universities for specific requirements.

Hi Shoaib,
To pursue a Bachelors degree in Germany, applicants must complete 13 years of education, that is an additional year of formal education after 12th. You may meet this requirement by:
clearing the Feststellungsprfung exam (Studienkolleg)
or
Enrolling into a Bachelors degree and completing the first year
or
Clearing the IIT JEE Advanced
Programs are taught in English too keeping mind the flow of international students. Refer the DAAD website for more information. You will find course and university information as well. Here's the URL

Dear Varakavi,
Let me be very honest here. The answer would be a 'no'. Free seats for international students are very hard to get, moreover your academic hardest till the 6th sem are not too impressive. If you can get at least a 9 on 10 with superb research activities and even publications you may be considered.

Both countries have their own benefits and if you are looking for job opportunities post your studies, check the skill shortage list for both and decide. Cost wise, Germany is a better option but you need to learn German though the courses might be offered in English as well.
USA, the jobs are quite competitive right now and with limited visas issued every year, you need to be competent enough to get sponsors.

Hi,
Certificate courses may vary in duration and to get better guidance, share your qualification and experience.

Hi,
I would suggest you to write to the universities directly to know if they offer some kind of a credit transfer for you based on your profile. Just check the following link if that suits you.

It is good but you should complete B2 or B1 German level to study there.

Hi Nikunj,
Please specify if you are looking for Bachelor's or a Master's course.

Getting a free seat is almost a 'no'. You must be extraordinarily bright to get into a national university with no tuition fee. Unfortunately a score of 6.4 is very low. If you can manage to get a CGPA of at least 8 out of 10, chances of admissions would still be there in a few universities. But, tuition fee is anyways minimal in Germany.
