What should I do?

Currently am in Grade 11 and in the process of selecting Grade 12 courses… I hate school but I have pretty high grades (high 80s low 90s)

Anyway just wondering if it would be a smart idea for me to do functions, calculus, english, and accounting in one semester and then in 2nd semester do data management and religion online. Meaning I would not have to come into school at all for second semester…

Is this a smart idea? Am I fucking myself over? Will I get FOMO?
