BDS

Dear,
BAMS counselling will be done separately. You can take part in it.

Why do you want do MBA? Dentists have good income. Even after MBA in hospital management, there will be no increase in your income.

Common knowledge would suggest that a BDS is better. But with recent growth of awareness in ayurveda, BAMS, which is usually looked down upon, is an equally good option.
Every option can be right for you if you have the right aptitude and temperament for it.

The higher secondary examination or the Indian School Certificate Examination which equivalent to 10+2 Higher Secondary Examination after a period of 12 years study, the last two years of study comprising of Physics, Chemistry, Biology and Mathematics or any other elective subjects with English at a level not less than the core course for English as prescribed by the National Council for Educational Research and Training after the introduction of the 10+2+3 years educational structure as recommended by the National Committee on education.

Hi Komalpreet,
You must have above 75% to pursue any Bachelor degree course in Canada.

Dental Council registration is a must in all countries for work as dentist. Clinical Masters requires registration and as such no country will you to do this.

You can't get any seat in any college.
Try next year because there are only 65k seats for MBBS and 25k seats for BDS.
Good luck for next year!
