For three years, Microsoft Learning has held multi-day virtual conferences called Microsoft Certified Career Conference. Two of the tracks you might find helpful are Exam Crams and Super Cert Me. These sessions are recorded for all registered attendees to review.
Even though the conference has passed, you can still gain access to these recorded sessions. That's three years of valuable content, at no cost to you. Visit www.mscareerconference.com/ and register/create a profile, then click on the blue "Microsoft Certified Career Conference" tile in the center. (Bonus: You can also listen to Stephen Rose's keynote address from this year's conference!)
