Start with what you know
Start by listing the subjects and activities you enjoy, those you find demanding and those you have not yet tried. Discuss the combinations your school actually offers. A career interest is only one input; prerequisites for later courses, your study habits and available support also matter.
Check the real options
Compare two possible subject combinations using the same questions: what would I study weekly, what future routes require these subjects and what would I need to practise? Ask the school for current rules rather than assuming a stream name guarantees eligibility everywhere.
Make one useful next step
Try one small activity from two different directions. Keep the work and describe what felt engaging or difficult. Bring these examples to a conversation with a teacher or counsellor instead of asking a quiz to make the decision for you.
