Please give me some advise. Thanks,

I want to know whether two months is enough to prepare FRM Full exam? I could not study as full time. I passed CFA level II exam, and my current working experience is not counted as CFA experience but is counted as FRM experience. And I already got 2 year working experience. So I think maybe getting FRM is quicker and later I can change to an investment job. I can prepare for FRM by the end of Sep, so there are only two months left. Is that enough? Any suggestions are appreciated. Thanks,
