Apartment and Schooling in Germany?

Hi Everyone, I am Elizabeth and currently working and living in Singapore. I am waiting for the draft of the job offer of our HQ office since there is an position that I am applying. I had a conversation with our HR yesterday, it went well though they need to organize a lot since it is their first time to employ from abroad. Anyway, I have a daughter and she is 10.5 yo, though I discussed with our HR to assist in my daughter's schooling. There are 2-main items which I would like to ask for opinion: 1.) schooling - are there a lot of international schools in Gottingen? Our office is in Moringen which is 20-minutes away from Gottingen. I am a bit stress now on how to arrange my daughter's schooling. 2.) apartment - i have checked some forums and it seems like there most apartment are unfurnished. i need a 2-bedroom flat a few km away from my daughter's school if possible. I hope that we will have a smooth transition in Germany. Thank you very much for your kind advise in advance!
