IGCSE生物，看看Topic1都學(xué)些什么內(nèi)容？

 

　　這可能是IGCSE中最簡(jiǎn)單的科目之一，通過(guò)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(dòng)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(gè)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(wèn)題模式往往不同。對(duì)于生物學(xué)來(lái)說(shuō)，p1的實(shí)驗(yàn)性更強(qiáng)，而p2的實(shí)驗(yàn)性更強(qiáng)，理論性更強(qiáng)。

　　某些問(wèn)題會(huì)不時(shí)重復(fù)，建議記住標(biāo)記方案點(diǎn)，以避免不必要的標(biāo)記丟失。

IGCSE

　　長(zhǎng)話短說(shuō)，生物學(xué)很有趣，只要一點(diǎn)誠(chéng)意和練習(xí)就可以掌握。
