What ways are there to sync multiple tablets with same information from PC?

[AC Question]

We have several (over 50) Samsung Galaxy 5 Tablets that we purchased for a non-profit. We want to upload the same information/apps across all of the tablets from either a Master tablet or via a PC. What is the best way to do this? We are using these tablets for educational purposes and need to be able to do it quickly and efficiently- not one at a time.
