Having passed both the CBIP exam and 70-448, I can tell you I feel no smarter for having passed either exam. All it does (for me) is tell me I can cram a lot of info in my head for a short period of time.

There is NO exam guide that can prepare you like experience, learning interest, the right mentor, and people sharing their knowledge (expecting nothing in return). Not a day goes by where this site hasn't taught me something new every day.......be it about RDBMSes, BI, T-SQL...whatever.

Congratulations on passing 😎
