I am 43 years old, married with kids.Can I do MBA in Canada?

No..you can go it alone. I am an agent and you do not need me and if you seek my help you are safe. You have no age restriction in Canada for applying for student visa. You will require GMAT 670+ to enter Queen’s School of Business the top ranking institution , in Kingston , Canada. It is a highly expensive school which charges around Rs30,00000 for the entire program but you would require another 6.5 lakhs to support your stay. There are also universities where you can do MBA for Rs.12 + lakhs . Such Universities have
- 12 months program. Where
- No GMAT score required.
