^ Sarah. Ah, yes. Isee what he's asking.
Well, I did it in year 11 with the intent of dropping it in eyar 12. I reckon you should do it, since it's not a LOT of work (can't be - only 1 unit) and even if it doesn't teach you any ideas you can use in Advanced English (it might, though), it is both good practices and good for improving things like crtical thinking (in the context of the English curricula), essay writing, and clarity. I've found that, at least. It was also a good motivator for me to do better in Advanced English.
And there's a bonus - you might decide to keep it.
