Each random answer would indicate something to someone, and with so much info given up willingly(I’ve just seen a question “Tell me something about yourself”) Could I.D. theft be possible if somone paid enough attention?

My daughter (US citizen) has left school in her senior high school year in Sydney Australia and plans to take the GED pursue higher education at a community college in California. Any opinions or suggestions welcome as to her preparation for the GED. Thanks in advance!
