@Cantpasssagain1, from what I've seen, it is very rare to get into the core M&A practice from audit, although this can differ in smaller offices where there are more Swiss Army knife-type people. In Europe, a transfer to M&A would be more realistic, but that's a lot of hoops to jump through. Ex-auditors do make up the bulk of FDD and Valuations, so those are a more realistic, but still very difficult transfer due to the high competition. FDD -> MM CF or Val -> ER are both realistic exits if either interest you. I don't think the CFA would make a difference in any case except for a Val transfer.
Also, re:MBA and other stuff, I agree with @Anthony a lot more than I agree with @Thunderlips. M7 isn't necessary though, I've seen plenty of people get into IBD at good banks like Barclays, Lazard, BAML, Wells, RBC from the likes of UNC, Indiana, USC, Texas, Georgetown, although it is harder.
