I'm looking to get a few IT certifications and a simple search on Google yields tons of sites/companies that offer cbt's. I'm specifically interested in Win Svr 2008/2012 and Exchange Svr 2010. I had thought about just reading the books myself, but CBT's might be a better option since I'll have access to videos etc.
Has anyone done CBT's through a company or web site which you would have recommended?
