重post general reminder:

1) 記得要小心審題
啲人往往唔中point就係因為寫晒一大堆看似相關嘅point,但係實際上唔係答緊題目。
例如2015Paper 2 Q1(biii) 題目叫你Explain why there is an increase in blood flow to the skin during exercise. 有人答左significance/importance of increase in blood flow to the skin,而唔係答reason for the increase in blood flow to the skin.

2) 記得留意題目提示字眼(hints)
原理同第一點一樣,你必須扣題作答先會有分。
而某部分題目會有一啲提示字眼,例如但不限於With reference to.../Based on...。其實提示字眼已經隱含左答題方向,而通常你從答案中反映到你有用hints,你係會拎到分。
例如2016Paper 2 Q4(ai) 題目叫你With reference to the roles of neurones and nuerotransmitters, suggest why patients with Parkinson's disease demonstrate the above symptom. 答案total2分,1分係比role of neurone (to produce neurotransmitter),另1分係比role of transmitter (coordinate voluntary response/muscle contraction/muscle coordination)。

3)留意題目嘅情景(scenario)
同第二點有少少類似,你係要運用個情景比你嘅information去作合理推斷/解釋。
例如2015Paper 2 Q1(aiii2),佢比左一句statement: HCG prevents the degeneration of yellow body. 問題問 : Based on the action of HCG, explain why the woman did not experience menstruation。你係要base on句statement,然後繼續作推論。
呢題相當容易,但係面對陌生情境(unfamiliar situation),如果巴打無頭緒嘅話,可以參考下情景比你嘅每一句,然後嘗試作合理推斷/解釋。


仲有三日頂埋佢!!

You don't need to know how for DSE.
Those words such as neurosecretory cells or neurohormones aren't words that will apear in DSE, unless otherwise specified in the paper. Just in case you don't know.

點分 chromatids,chromosome and chromatin?

樓主上個po有答過

3. Chromatins: very tiny threads which cannot be seen when the cell is not dividing
Chromotid: one of the copies of the chromosome if the chromosome is replicated.
Chromosome: two chromatids (having two copies of DNA) join together after replication, or just one (having one copies of DNA) after sister chromatids separation

其實上個Post有位Merlot巴打另外有講:
Chromosome係睇centromere。換言之,right after DNA replication,兩個chromatids痴住同一個centromere,所以就視為一個chromosome。Sister chromatids separate之後,每個sister chromatids都有一個centromere,所以喺呢個stage,佢哋係被視為一個chromosome。

巴打有冇d難既題目推薦下?
做完2015個份,已經想死,錯一半以上

如果你真係連50%都冇,咁你應該做返好pastpaper先。2015年已經係最淺。
時間無多,做by topic MC練concept, lq睇marking, 吸收得幾多得幾多。
