Hi kyla,
I hear you well

..
Hence why is some of the conflict in reading for a junior.. No strangers guidance should ever substitute your parents.. theres a zillion other reasons also..lol. but that would take an assay..
You know you are welcome to learn a little palmistry at any age, it could be interesting for you.. but never create a life dictated by what's in your hand or the stars.. these are great tools when used properly. remember at any age the future is ours to create, astrology and palmistry may give us clues in what challenges we may face.. but nothing written there takes place of the powers to achieve what you want from you.
Just another mothers take on what you want versus what your parent want for you.
It seems your parents have set a high goal for you. they believe in you in being able to achieve this.. if you study towards this you are keeping your options open, ie to pursue just this latter.. you may get a taste for it, or follow your own desires when your older and have properly weighed up the pros and cons.
lol. and hey if your parents are going to support you in this area of study take it... at least when its done, and you happen to follow a different path it can be shown to potential employers how much it means to you that you have choices, and that is the one you chose.
Dont think for a moment what you want is unachievable. there is no such thing.. ( unless it relies on someone else bringing it to the tale of your life.. )
Many people who have been successful in arts, music, dancing, sport, all did these things as a "side line" hobby, or serious interest.. while still working towards academic or seemingly more practical achievements.
The path to success and happiness is to be balanced, mind, body and soul.. so sure keep room open for doing this thing as your "thing for you" while you study.
Imagine if someone told Leonardo Davinci "No you cant be an artist... see your hand says you are a mathematician "
Keep the enthusiasm up for learning, creating, and living. your a good girl. keep shinning.
