Help w My Subject Combo

Hey folks, I’m fresh in 11th and my subjects are Biology, Chemistry, Mathematics, Psychology, and of course, English.

I have a Chemistry test tomorrow and I am nothing less than cooked and fried for it. For now, I’m going to let it pass because I didn’t study due to multiple ongoing things.

However, do y’all think this combination is strategic enough to, er, stick to till boards in 12th? I’ve seen too many kids plummeting down to subjects they don’t like just because they couldn’t score well.

Also, what are the toughest/trickiest chapters in these subjects that throw off most people?

Appreciate it :)
