B.Com Finance

There is no particular route that you need to take to be able to pass your three levels of CFA. Programme. The content is very specific and will require a lot of self-study. What would help is (post your Bachelor's course) to first get some work experience or a Masters in Finance or MBA in Finance, so that you are better able to understand which area in finance appeals to you. The CFA Programme will equip you to work in an investment related field, which is only one area of finance. So, take some time to understand why CFA. That said, if you feel convinced about CFA at your stage, then any degree at the Bachelor's level should be fine. You could do BBA, BBS, BBM, BA (H) Economics, B.Com (H), BA (H) Maths, BA (H) Statistics, BFIA (I am assuming that the Science/engineering/humanities stream does not interest you).
