I passed CFA L1 at last. I was Band 3 in Dec 2013 exam. When I asked for advice in this forum last time, some folks replied CFA is not for me and I am wasting my time and money. But I decided not to listen to them and gave my best shot and Passed. Yes, I am from non-finance background. But I always believed if you put your mind and heart to it you will get it.
