I've just graduated from the university of manchester and am taking a year out, applying for grad schemes for 2013 entry in the process. I was initially planning on focusing on big 4 apps, which I am still doing, but I'm keen to also try for some of the strategy houses, such as Marakon, which I found to be a particularly appealing company to work for. So as I have spare time, I was thinking of taking an advanced course in Microsoft Excel to get ahead and differentiate myself from the Oxbridge and LSE candidates. Can anyone recommend any courses in Excel, or any particular aspects of Excel that I should really learn and become an expert in? Or anything apart from Excel for that matter?Thank you
