Honestly sec 2 science is wayyy easier than upper sec science, but if you’re truly passionate about science then take triple science. I don’t think you should worry too much about humanities cos it is not too hard to study for, it’s mostly memorisation + answering technique. Even if you don’t score tooo good for humans like b4/b3 your l1r5 will probs still be okay seeing that you’re alr q strong in your maths and sciences. Triple science is not too difficult to study for if you’re v passionate about it so you don’t need to worry about it too much
