@ rid3r. The grace period you mentioned is for 2 years max from getting your degree. If you fail to secure a flying job it's tough luck and you have to come u with a re-payment plan that suits your current income.
That 50000BD is low compared to what some of us paid to get into the right seat....
Going rate nowadays in Holland is 85000BD with no job security and a 7-8% interest rate. Like job security ever existed!
