If you want to serve your country are your circumstance are such that you don't anyone but yourself to support in the near future. Go for CSS it provides you with the opportunity of a life time. Plus its age restricted only people under 28 can actually take the exam.

CFA isn't as tough as people think it is. Many a people assume that CFA brings in a lot of cash I honestly disagree. I am my self a CFA level 2 candidate. Plus I aspire on doing an MBA too. But the thing is CFA and MBA are not age restricted. I can do them when ever I want to. You can take these exams even when you are a CSS officer. So no worries here.

Go for CSS if this don't work out you will always have CSS. win win for all.
