I have to crash two subjects. I have some ideas but what is ideal for me?

My subjects options sheet for S5 was supposed to come out on the 20th but my class was given it early today for some reason. I'd rather not mention my prelim results but because of those im now having to sit my nat 5's next year (long story...)
I have to pick 5 options but I only really care for 3 of my subjects which are Apps of maths, english and music. So i'm thinking of subjects to crash.
I'm sure about picking administration for one. I was fairly good at the lessons we had for it back in S2 so I don't see a problem picking that, but i'm stumped on what to pick for the second subject. I was thinking of picking a science (anything but physics) however all subjects there have its flaws.
Is there any other subjects that you guys and suggest? This doesn't have to be immediate, so any ideas are appreciated
