Unfortunately, the current educational system is not designed to cater to one's interest, speed or intelligence. It's a factory system designed to produce generalist that can do many things but none so professionally.

My advice is to go through with your studies. Do well but not necessary to have good grade; let alone full marks. Your results will be irrelevant unless your interest is to pursue research. Just ask your parents if they remember their grades in school or if they asked their employee (or asked by their employers) about their grades.

Spend enough time for your studies, then put your other energy into subjects that interest you. Move from one interest to another until you find that something you want to spend your life working on.

That being said. You will learn in future that sometimes, survival requires you to do something that you are good at but does not interest you because it pays well. You will have to choose when the time comes but.. live life to the fullest while you are young.
