Great guestspeakers...

Seems like this term we have some really really good guestspeakers for my lectures. I just read the list and it includes CFOs, Private Equity Managing Directors, Heads of Strategy, etc. from such great companies as Royal Bank of Scotland, McKinsey, Barcley's Capital, BNP Paribas, Goldman Sachs, etc.
Guestspeakers basically teach one lecture session on a certain subject and give us some really valuable inside into the practical side of how things work.
I'm really looking forward to this and hope they can make it...in the past, the line up of the guest lecturers has changed regularly on short notice, because it is almost impossible to plan with people in positions like that. Nevertheless, the lecturers have always been able to find appropriate substitutes through the school's network in case on of the speakers cancelled in the last minute.
