Dear Caring,
I’m sorry your parents seem to belong to those we call “old school “ and who do not realise that children today excel when they like a particular profession or course.
Talk to your advisor or principal to try and explain to your mother that you will not do well if you don’t follow your heart and do the course you like.
Also find an uncle or aunty who your parents respect to help you convince them to let you study a course of your choice.
Good luck!
Aunty Grace.
