It is better to do her Intermediate and take up Art & Crafts courses part time after college hrs or on weekend for her personal enrichment. Let her explore her creativity while she completes her Intermediate. There are online courses too.
If she is very much interested in the creative field, she could take up BFA.
Let her do a proper and valid undergraduate degree rather than a diploma.
To make a career in Creative field, one needs to have lot of passion. She could later specialize in whatever she is interested in after a basic undergraduate degree. This would also provide her job opportunities in future and if interested she could start something on her own.
Thanks Mickey for your suggestion.
