Hi All,I've found this forum pretty helpful so far, so thanks to all of you who contribute regularly for making my life so much easier!I've recently been hired as a Business Analyst at McKinsey (starting in a few months.) My background in Excel is alright, but I've been told that having an edge in Excel can produce a gigantic edge in general, and so I've been looking at online courses. Can anyone recommend a super in-depth course that's good? I've been looking at ones that specialize in financial modeling-- is this the right direction?Happy for any helpful tidbits.Thanks,David
