I did Chemistry, Physics and Biology. For year 12 next year (next term to be more exact), I am dropping Chemistry. I find Physics and Biology both a LOT more interesting than Chemistry. Well, in truth, all three would be interesting but the thing is, I don't understand Chemistry. And yes, I agree that Physics is more science and maths whereas Biology relates more with the humanities, though it is still of course, science.
This was a tough question for me but I finally ended up choosing Biology because these three terms, I've found out that I've chosen the wrong choices, choosing the three sciences... I'm not a maths/ science person, more of a humanities person. But now it's too late, have to stick with it for the rest of my HSC... *sigh*
