So currently I'm doing english advanced, chem, physics, modern history, and extension 2 maths. I've realised that i need more time to study and i'm planning to drop down to 10 units mainly because of extension 2 maths. I'm doing pretty decent in all my subjects except for Extension 2 averaging probably low to mid 70s and i found that i'm spending a lot of time on it. So what i planned on doing was drop modern as it is the lowest scaling subject i have but now i found out i'm ranked first in the grade... I have no idea what to do, should i drop extension 2 or modern? Please help
