這可能是IGCSE中最簡單的科目之一，通過定期復(fù)習(xí)和練習(xí)歷年P(guān)ASSPAPER，可以很輕松地搞定這一學(xué)科。教學(xué)大綱涵蓋了種類分類、動物生理學(xué)、植物生理學(xué)和遺傳學(xué)等廣泛的主題，使其更加多樣化和令人興奮！從學(xué)生的書中學(xué)習(xí)規(guī)范，一個A*很容易哦！
考試本身分為p1和p2。兩者都涵蓋相同的主題集，但問題模式往往不同。對于生物學(xué)來說，p1的實驗性更強(qiáng)，而p2的實驗性更強(qiáng)，理論性更強(qiáng)。
某些問題會不時重復(fù)，建議記住標(biāo)記方案點，以避免不必要的標(biāo)記丟失。
IGCSE
長話短說，生物學(xué)很有趣，只要一點誠意和練習(xí)就可以掌握。

文章總結(jié)：以上就是關(guān)于IGCSE生物，看看Topic1都學(xué)些什么內(nèi)容？的全部內(nèi)容了，考試本身分為p1和p2。兩者都涵蓋相同的主題集，但問題模式往往不同。對于生物學(xué)來說，p1的實驗性更強(qiáng)，而p2的實驗性更強(qiáng)，理論性更強(qiáng)。
