Career and marriage prospect

My daughter is born November 1, 1996 in Baltimore US
1. She has applied to some graduate school programs for school psychology and wanted to know if this will be a good career track for her and she will make good progress in this field?

2. she has broken up with 2 boys in college and currently over past 1.5 year has not had any boyfriend and is alone. All her friends have boyfriends. Wanted to know if she will be able to find someone suitable in her life soon and hope to be married happily?
Thanks
