IB大考押题：IB生物科目重点内容分享

今年的IB大考已经进入倒计时阶段啦，相信大家都已经在紧锣密鼓的复习了！那么，你知道有哪些重点是一定要熟读于心，有很大的可能会考到的嘛？

去年大考前，我们的教研团队也针对大考进行了一波押题，不得不说，这命中率真的是太！高！啦！传说中的“神仙导师”可能就是这样了吧

“考的全会！”

有一个“神仙导师师”的优势就在于——每一个考到的知识点都带着你复习过啦！

看到试卷的时候直接松了一口气，这些知识“我！全！都！会！”

最想成为的IB凡尔赛达人是什么样的？就是在走出考场做反馈的时候轻飘飘的说——

“感觉也没有很难嘛。”

主要是因为导师真的教的太好啦！到底是怎样的经验和对知识点的精准把控，才能让考试的时候考的和导师师上课讲的重点完全一致啊

“讲的全在点子上！”

是不是很羡慕去年的同学？不要着急~

“神仙导师”们又带着他们的押题来了！最先更新的是IB生物科目的重点内容，赶紧拿小本本记下来吧！

这些图你都会画了吗？
