How the 25% works25% 的算法
- Your first subject is the full price.第一科按原价。 Whichever one you pick, and whatever length you choose. 无论选哪一科、选多长期限，都一样。
- The second and every one after is 25% off.第二科起，每科减 25%。 It applies to the same account, for the same period. It is not a limited offer and there is nothing to claim. 适用于同一账号、同一期限，并非限时优惠，也无需申请。
- All three of a stream is cheaper still.选齐一个组合的三科更便宜。 If you are heading for three, look at the stream price before you buy them one by one — that page is here. 若打算买满三科，请先看组合价，别逐科购买——组合页在这里。
Supplementary subjects辅修科目
English, Geography, History and Combined Science are supplementary subjects. They are not sold on their own — they open once you hold all three subjects of a stream, and then they are a small price each. 英文、地理、历史与综合科学属于辅修科目，不单独出售。选齐一个组合的三科后即可加购，每科价格很低。
