Sync will blow up everything

I spent enormous time putting up all my schedule on my ipad. I tried to sync it with my phone. Instead of putting all my schedule into my phone, it just blew up everything I put. Also it doesnt make sense to me that the app asks to put another semester when I start it. It should ask me to sign in and sync it automatically. This is ridiculous.
