Study / Son wanting to go to school in Poland [7]

Hi all,

New here. Just wanting some advice and info from anyone here willing to share. My son wants to go to Poland this winter as part of a study abroad program. He says it will be an experience of a lifetime. My concern is first for safety and money. If schooling is paid for about how much should we expect his extra expenses to be? I know this is a very broad and vague question but any input would be appreciated. Thanks!
