♥For You♥

在所有的国家当中,我选择了出世再新加坡。
在新加坡里,我选择了就读学林小学。
在学林小学里,我认识了很多朋友。
在所有的朋友里,很多都会影响我。
在影响我的时候,我分心了。
分心之后,小六PSLE考了221。
考了221的成绩后,应该选择中学。
而在兀兰地区里,我选择了永青中学。
在永青中学,朋友的数量不比小学少。
在所有朋友里,认识了你。
而你,却让我不知道,我将来,会是怎样的一个人。

♥Without you♥

Chemistry and Biology paper

Chemistry:
It was quite alright...
Easier than the other papers.
Just confused with Gas and Gaseous.
Hydrogen Gas and Hydrogen.
H2 i put Hydrogen Gas
dunno correct or not.
Hong Chye thinks that it is acceptable.
He sec3 so i completely trust him.

Other parts of the paper....
Umm......
Only the first part of Section B.
The 'Name the apparatus used for these' or something.
That one i quite scared.

Biology:
It was freaking hard to me.
First 3 questions i die already
I really suck at Classification.
The others still can do.

I nvr believe....
'Define the term Enzyme' Would come out in the exam.
I did not even go and memorise it.
Somemore 2marks seh.
diedie.

Then the next problem is
whether nucleus is present in the following.
Red Blood Cell, (Forgotten(But confirm have nucleus)) and Xylem Vessel Cell.
At first i wrote - + -
cause the question says
A dead Xylem Vessel Cell or something.
then i think the dead cell have no nucleus.
But then,
i dunno why i keep thinking that it has a nucleus even if it is dead.
Then i changed to - + +
Ask Mr Lim about this,
he said that the answer is
- + -.
Then i was like holy shyt.

Another question was
The Classification table.
I dunno how to spell the dict........
Then that question nid us to enter the Sub-heading.
Above Monitor Lizard i put Cold-blooded animal.
and the other i put Warm-blooded animal.
I think I am stupid by putting that.
Cause i thought that Vulture is cold-blooded.
Then on top Zebra i put With stripes,
on top Hyena i put without stripes.
On top Vulture i put can fly,
on top Ostrich i put cannot fly.
I dunno whether acceptable or not.

Then the next one is the cell thingy.
I was confused whether to put Plant cell or Stem cell.
Cause they say wat type of cell.
Then i put plant cell.
After that they ask wat does A made up of,
A is the Cell Wall,
I actually put Cellulose.
then i changed to Starch.
Cause suddenly thought of that worksheet
the permeable thing.
Then i ask Mr Lim,
He say the answer is cellulose.
I nearly gone mad.
but there was examination going on in the hall.
so i didnt shout.

The next question is below that.
I think it ask about the Vacuole.
That question i put Cellulose,
cause i at first put Starch,
then since in the Cell Wall i put starch,
so below it i put Cellulose.
Then at the end sure wrong.

Another question was the Structured Question(10marks)
The whole thing i dunno

The first one is:
Give an example of protease.
I put Pepsin.
The others put like Tyrpsin or Poly.....
I dunno how to spell that thing, I onlyknow first four words is poly

Then the next question is
What is the product of it? (The 'it' refers to the protease)
Then at first i dunno what the hell are they talking about.
Then i just put anyhow
Amino acids.
Then go canteen saw my frens
ask them wat they wrote.
Then they also wrote Amino Acids.
Then i lucky.

Believe me,
to me, The Biology paper was HELL!!!!

  1. Guan Xin, pepsin is correct. :D

  2. Because pepsin is found in the stomach and the stomach can only digest proteins. So, if pepsin is found in the stomach, it should be a kind of protease. :D
