Reflections On Term 3 Personal Performance

We had a long break and after that, we had to buck up and study hard again. Honestly, I would have to admit that after the holidays, I did not really want to study but just want to slack at home, however, during the second week, my "fighting will" was re-ignited. This term, I was quite worried at first when we heard that we would be learning more on Biology as when Chemistry was introduced to us last term, I did not performed well. I have read some books about biology beforehand because firstly, I was interested in Biology and secondly, it could help me now. Through the assignments, I would say that I am quite good at Biology. For my goal of getting an A1 this term, I revised a lot before the test. However, even if we do put in effort, sometimes, we do not get what we want to achieve. The questions asked were mainly Chemistry questions and also, whatever I studied, did not come out often. I got a B3 for this test and although I did not deprove, this result is definitely not satisfactory. Most of my peers, even those in remedial, could be able to get an A1 and yet I could not. I was quite depressed to know my results but I hope that for the EOY exams, I would be able to just get an A1. However, I think that it is my fault that I did not revise fully so that even if any questions come out, I would be able to answer them.
The topics that we learnt this term are as follows:

Models and Systems(Theme)-
1)Microscope, Cells and Structures(i.e. Draw cell diagrams, use a microscope, explain the significance of specialisation etc)

2)Diffusion and Osmosis(i.e. Define diffusion and osmosis etc)

Energy(Theme)-
1)Digestion(i.e. Explain process of digestion etc)

2)Photosynthesis and Respiration(i.e Compare them)

I enjoyed the lessons regarding the digestion the most for this term as it is very interesting. Although we learnt this in primary school already, we were taught something more in-depth. Last time, we were only taught about the stomach, mouth, small intestines, large intestines and rectum but this time, we were taught about the oesophagus, liver, gall bladder and the type of enzymes the different parts of the system contains and release. Also, for the topic of cells, we also learnt more than what we did in primary school, for example, in primary school, we only learnt the different parts of the cell and what they do but only in secondary school did we realise the significance of specialisation. As for the diffusion and osmosis topic, we actually already learnt part of it from the Brownian motion topic last term( the definition of diffusion) but for this topic, I find that it is actually quite easy to understand and I would say this topic is very fruitful as it applies in a lot of things, for example, in our cells.
