The International DMD is for somebody who is competitive.
You can ask yourself first, are you among the best of your counterparts so that you can enter a public institution and graduate with a good looking gpa? (I say so because, in some countries, students can enter a dental school just because their parents are willing to pay a tuition of 3000 USD~ 5000USD a year for their children to have a "DECENT" job)
If you are Ad com members, then how would you view anyone with several attempts in Part 2 ??? Will you believe this guy would graduate successfully from the program so that the dental school will not lose money for giving him the seat???
Perhaps, your dream seems not to be realistic at the first place.
You can still take another attempt in the P2 and you may finally pass it. Then you gonna apply and apply...... and why don't you accept the reality much earlier and be a GOOD DENTIST in your home country?
Anyway, I sincerely wish you could slap my face someday by proving yourself. Good luck, buddy!
